Professional, diligent, and efficient with her time, she is a no-nonsense designer who can navigate spaces well and deliver a concept that meets both aesthetic and budgetary wishes. Nadja was kind enough to introduce us to her industry contacts for us to complete our project. I would highly recommend her to help you carry out your vision! ### All 45 reviews **★★★★★ — Georgine Chokatos, Aug. 2026** > Probably the best thing I did in remodeling our primary bathroom was to ask Nadja to design it. Having done a bathroom remodel on my own recently there was just a huge difference in this project because I was working with an experienced designer. First, the design itself made such good use of not only the space but also the natural lighting from a skylight and window. Then the fixtures have turned out to be not only beautiful but also wonderfully functional--this includes everything from the shower heads to the vanity, mirrors, shelves and sliding door closet. I was saved an enormous amount of time and travel because she knew which vendors and what to order in the way of all the bathroom fixtures. A very important feature is the tile which I doubt I would have found on my own which truly captured the style I was after in an International Modernist house. It was also great that she worked with a contractor that she knew and trusted so communication was always easy. It is just so pleasing to have a bathroom that is so thoughtfully functional as well as aesthetically pleasing--I feel it fully captures the spirit of Bauhaus design that I was seeking in this project. **Comment from Knocknock:** > Thank you Georgine! It was such an honor to work on your amazing house!! **★★★★★ — sborisova34, July 2026** > We had very positive experiences working with Nadja and her team at Knocknock Kitchen and Bath Design. She worked with us on a complete remodel of our master bathroom and a secondary bathroom and helped us with design decisions for master bedroom. Nadja has an excellent eye and is on top of current trends. She is also very adaptable to different budgets and offered few suggestions on how to save as well as what is worth splurging for. Nadja was very easy to work with – easy to communicate with, working with us on our timeline, spending extra time, and open to revisions of the original design. Her team was very expedient in preparation of architectural designs for permit submission. We are very happy with the final products and would love to work with Nadja and Knockknock design again. I highly recommend their services. **Comment from Knocknock:** > Thank you Svetlana! It was a pleasure to collaborate with you! I appreciate your comments and the photos!!! **★★★★★ — Victoria, May 2026** > Nadja is an excellent designer with a strong eye for detail, creativity, and visual balance. She understands how to turn ideas into clean, professional, and engaging designs. Working with her is easy because she listens carefully, communicates clearly, and brings thoughtful solutions to every project. Her design work feels modern, polished, and purposeful. I highly recommend Nadja to anyone looking for a talented and reliable designer. **★★★★★ — HU-434983635, April 2026** > Working with Knocknock has been one of the best investments I’ve ever made in my home. Nadja is a true visionary with an exceptional eye for timeless design, quality materials, and how people actually live in a space. > > Over the years, she has designed my kitchen, bathrooms, bedroom, armoires, bar cabinetry, custom sinks, and more. What impresses me most is that my kitchen, designed over 20 years ago, still looks modern, elegant, and practically brand new. That is the mark of real talent. Trends come and go, but great design lasts. > > Nadja has an incredible ability to source beautiful, durable materials that stand the test of time, and every project reflects both style and function. Beyond her talent, she is also a genuinely kind, warm, generous person who cares deeply about her clients and their homes. > If you want someone with vision, integrity, and the ability to create spaces you’ll love for decades, you must work with Nadja and Knocknock. **Comment from Knocknock:** > Thank you Karen! It has been a pleasure and an honor to work on your amazing house! **★★★★★ — hnyesf, April 2026** > Nadja was a wonderful partner in our recent kitchen & bathroom renovations. She is creative, honest, and easy to work with--and most importantly listens to and challenges the client to ensure the final design will be something they love for decades to come. Vendors with whom she has connections were outstanding, responsive, and produced high-quality work. While Nadja's official role was limited to helping with the design and plans for the renovation, she ended up becoming an invaluable partner through the entire course of the extended project. She was always a text or email away--and helped solve problems that were not her responsibility or purview. She makes it clear that her goal is to support the owner at every stage and is someone who we supremely valued when construction issues arose (frequently) . We recommend Nadja for her creative, knowledgable, and connected expertise. But it was her 'can do' positive attitude and no-nonsense sense of humor that got us through things this year (again, above and beyond her official responsibility). We endorse Nadja's services without reservation and will certainly call on her again should we ever have additional needs. **Comment from Knocknock:** > Thank you so much Heather! It was such a pleasure to work with you and to get to know you! > Nadja **★★★★★ — 314 Design Solutions, March 2026** > I’ve had the pleasure of working with Nadja for several years, and she is one of the most detail-oriented designers I’ve encountered. She has a strong understanding of cabinetry design, space planning, and how to balance aesthetics with functionality. > > What I appreciate most about working with her is her collaborative approach. Nadja really listens to her clients and respects their vision. Rather than pushing her own style, she works with what the client wants and thoughtfully adjusts the design to make it work both aesthetically and functionally. It truly feels like your project and your vision, supported by her expertise. > > Nadja has designed two kitchen cabinetry showrooms for my company, and both turned out beautifully. I recommend her whenever I have the opportunity. She’s talented, professional, and a pleasure to work with. **★★★★★ — Owen Shi, Oct. 2025** > I’m grateful to have collaborated with Nadja’s team for our 3 modern bathrooms remodel. From our first chat to the construction beginning, to me, Nadja is not only our trusted designer, but also like a mentor guiding me to my ideal living space that I’ve ever dreamed of. Everything started from a few photos showing our tastes/preferences and a few functionality needs that we had in mind, Nadja transformed them into very feasible drawings that my contractors had almost no problem implementing. Her taste of choosing finishings per my request is literally flawless that we made little change on. The contractors that she recommended were all super competent and approachable. The final results are so amazing that average 5-star hotels can barely reach. Lastly but most importantly, with her guidance throughout the journey, my knowledge in remodeling has grown to a high level that I could only dream of. It was a truly unforgettable journey. **Comment from Knocknock:** > Owen thank you so much! It was really a pleasure to collaborate with you, and I am so happy that you love your bathrooms! > Nadja **★★★★★ — S M, July 2025** > I recently completed a full kitchen remodel and had the pleasure of working with Nadja, and I cannot recommend her highly enough. From start to finish, she was incredibly thorough, detail-oriented, and truly went above and beyond to bring my vision to life. > > I came to her with a collection of inspiration photos and a list of functional needs, and she managed to translate all of it into a kitchen that is not only stunning but also highly practical and cohesive in style. With her background in construction, she was able to bring more to the project by giving lots of advice down to the small details while keeping design and functionality at the forefront. Nadja has a clear understanding of how to make a space both beautiful and livable, and my dream kitchen would not have been possible without her. > > What impressed me most was her work ethic and focus on her client's needs above all else. She was also excellent at coordinating with the contractor, ensuring the design plan was followed closely and holding everyone accountable throughout the process. If you're considering a kitchen remodel, I wholeheartedly recommend Nadja —she is professional, creative, and truly dedicated to her clients! **★★★★★ — Stellalux Construction, June 2025** > I'm a general contractor based in Oakland for the last 20 years, and have done a few kitchens and baths designed by Nadja over the last 7 years. Her style of collaboration is as her style of design: clean, streamlined, personable. Besides her style, I like how each of her jobs has their own unique features; a kitchen bar made of salvaged barn wood with a story to it, a shower niche that runs wall to wall with lighting; just the right accent tile or light fixture, shelf, etc. that gets the most out of a space. Whatever a client is looking for, she prioritizes their visions, fills the gaps with her own, and produces something every time that is unique to itself. Her and her team are super organized, and her extensive connections with material and accessory vendors keeps the project moving, as does her own prompt response to any questions or issues that arise during the remodel process. I recommend Nadja! **★★★★★ — Pointvertex Construction and Remodeling, March 2025** > I've known Nadja for around four years, connecting at client projects and industry events. Our recent collaboration on a specific project showcased her expertise. Her team at Knocknock Kitchen and Bath Design was outstanding in their communication, prompt and clear, which kept our project moving smoothly without any delays. Nadja contributed innovative ideas and expert guidance, which were instrumental in achieving our project goals. With her collaboration, we enhanced our customer service and delivered a successful project. Thank you, Nadja and team, for your commitment and work. **★★★★★ — Sanne Jacobsen, Sept. 2023** > Wanting a modern kitchen design with a compressed timeline, Nadja was exactly what I needed. She was efficient and knowledgeable, and she was easily available for questions and clarifications once construction began. Most importantly, I love the kitchen and bathrooms she designed for my new home. **Comment from Knocknock:** > Thank you Sanne! > It was a pleasure working with you! > Nadja **★★★★★ — Ernst Development Partners, Dec. 2022** > The Knocknock team was amazing to work with and took the time to understand our taste and needs. They are friendly and easy to communicate with and produced plans and renderings that were a perfect fit for our home. We will definitely be working with them on future projects. **★★★★★ — Laura Lopez, Sept. 2022** > Nadja is a total rockstar and I could not recommend her enough!! Right away during our initial consultation we totally clicked style and personality-wise and I knew immediately that she was the one to hire. I was a first-time condo owner, and also a first-time renovator, so in the beginning I didn’t know ANYTHING. She helped me stay within my budget while sourcing quality materials that were available domestically as I was super concerned with our timeline due to supply chain issues. She was consistently responsive within a couple hours for even the most minor of questions and worked seamlessly with my contractor. The 3D renders were awesome, submitted on time, and her measurements were perfect! > > I am thrilled beyond belief with the finished product!! I’m not moved in yet, but I feel such joy when I stop by my place and lovingly touch the counters, the plumbing fixtures…all of it. It’s everything I dreamed of, and more. She’s also the coolest person and it’s a delight to just be in her company! > > Thank you so much Nadja!! **Comment from Knocknock:** > AWW, thank you so much Laura! You were a joy to work with, I can't witi to have you move in and enjoy your new space! Thanks so much for the opportunity to work with you! > Nadja **★★★★★ — Carla, July 2022** > Nadja was great to work with. My kitchen is small and had an awkward shape. Nadja came up with a beautiful design, based on my needs. She valued my feedback and frequently reminded me, it was my house and I needed to love it. She worked within my budget and the end result is an incredible new kitchen and bath. I am thrilled with the finished product. I would recommend Knockknock without reservation. **Comment from Knocknock:** > Thank you Carla! > > It was a pelasure to work with you! > > Nadja **★★★★★ — Ivy Kam, May 2022** > It was a super fun process working with Nadja on my kitchen and bath remodel! I appreciate that she has all the professional knowledge to provide functional and aesthetic designs and solutions, but is also really collaborative and listens to and incorporate most of my ideas (and talked me out of the impractical ones). > > The process starts with the creation of a mood board on a shared google doc that we can both throw ideas onto (talk about kid in a candy store). After refining my needs and wants and evaluating/ measuring the space, she comes up with a draft plan including drawings and 3D rendering (see photos), which was amazing as I can actually "see" what the design would look like in my space, and you can see how uncanny the rendering resembles the finished space. > > From there she gave me a variety of vendors to consider, e.g. cabinets, countertops, appliances, various finishes, etc, and I ended up using most of her recommendations while finding some on my own (I'm a shopper and like to check things out on my own). She continued to help me think through all the different choices (paint 1 or 2? tile 1 or 2? grout 1 or 2? You get the idea), and patiently tweaked the designs until we have the perfect plan. When the cabinets arrived and some things weren't right, she worked with the vendor to set things straight and made sure I got what I wanted. I also ended up using a contractor Nadja recommended, who worked so well with both her and me, and completed my project pretty much on time (well, pandemic time) and on budget. I LOVE my kitchen and bath and I can't recommend Nadja enough! **Comment from Knocknock:** > Thank you so much Ivy! > I really appreciate you taking the time to write such an extensive review. You were a delight to collaborate with and your house looks amazing! It was an honor and a pleasure to work with you! > Nadja **★★★★★ — Sara Stoddard, May 2022** > I love my new bathroom! This is my second great experience working with Nadja. She wowed me the first time when she designed my new kitchen. I fell in love with her design aesthetic and keen eye for tasteful, modern detail immediately. Nadja is the consummate professional. Her and her team were outstanding every step of the way. I highly recommend Nadja for your next project! **Comment from Knocknock:** > Thank you Sara! > It was a pleasure working with you! > Nadja **★★★★★ — Studio Maxwell, Dec. 2020** > I am a fellow designer who was not feeling 100% confident about the design of my own kitchen. We were not acquainted before working together on this project. I reached out to Nadja and she took her time patiently guiding me towards a more functional kitchen design. Nadja is down-to-earth but professional. You feel as though you are working alongside an extremely knowledgeable friend. Thank you Nadja! **★★★★★ — jandiam, Nov. 2020** > Nadja is so smart, and super quick. practical and efficient with the details of kitchen design: she has a deep understanding of cabinet design. > She is a pleasure to work with. Highly recommended. **Comment from Knocknock:** > Thank you Jan! > It was a pleasure to work with you:) > Nadja **★★★★★ — Juliet, July 2020** > My husband and I did basically whole home renovation of a 100+ year old craftsman in Alameda. We worked with Nadja to design the kitchen, master bath and fireplace. Her designs, advice, guidance and resources helped us navigate decisions that spanned the gamut – cabinetry layout, appliances, fixtures, lights, pulls, tile, stone, etc. She paid attention to our style, but also helped us modernize our approach. The vendors, stores, websites and people she referred us to also made decisions easier as we weren’t paralyzed by too many options. > > Her attention to color, shape and lines helped us create beautiful spaces that are also super functional for our young family. She was always available through multiple modes of communication and showed amazing creativity when we had difficult circumstances to navigate. For instance, we couldn’t do a large horizontal niche in our master shower as planned, and she quickly came up with the idea to do a large matte black metal vertical niche, which is one of my favorite things about the bathroom. We also used a downward facing light fixture above the shower that was painted the same color as the wall to blend it into the background. I would have never thought to do that, but love the calm and modern vibe it creates, especially at night. > > Everywhere we went, folks knew Nadja and either smiled when they saw her or heard us say her name. She was such a pleasure to work with. Anyone who has the opportunity to do so, will enjoy the process. **Comment from Knocknock:** > Juliet - > > Thank you so much for this kind review! You and Mike were a pleasure to work with , and I am so happy that you get to enjoy your beautiful new house! > > Nadja **★★★★★ — Rave Photo, March 2020** > Mill Valley kitchen was my first project with Nadja who came highly recommended by many of my agents at Vanguard Properties. Nadja has designed personal kitchens and baths as well as multi-unit developments with strict budgets. As a photographer, I have taken photos of her work for 15 years and knew her affinity with clean and modern style. I started off with my own ideas and Nadja helped to enhance my vision and strategize my budget. I learned a lot from her, while she held my hand in navigating the whole project and trouble-shooting as needed. I made a new friend and got a beautiful kitchen! **★★★★★ — Jeffrey Walton, May 2019** > Thanks to Nadja for helping with our new kitchen and breakfast nook. Her multiple in-person meetings, clear explanations of what to expect, and straight forward billing made a stressful project easier. She was wonderful with our 4 year old who frequently accompanied us while shopping for cabinets and appliances. Her expertise in cabinetry was appreciated. She provided a masterful plan for our contractor and was present when the cabinets were delivered to make sure everything arrived in great condition. She was available and responsive throughout. We are pleased with our beautiful new kitchen! **Comment from Knocknock:** > Thank you Jeff! > It was a pleasure working with you:) > > Sincerely > Nadja **★★★★★ — Taja Leonardi, April 2019** > I am in the Kitchen and Bath industry and have watched Nadja work with many many clients. Nadja is one of the most talented modern kitchen designers in the Bay Area. She also has a practical yet warm approach that leaves you feeling that she hears you and at the same time does not waste time. Combined with her high integrity and knowledge there are very few designers who can give you MORE than what you paid for. I highly recommend Nadja with Knock Knock. **★★★★★ — Nancy Halloran, Dec. 2018** > I hired Nadja to create the plans for our bathroom remodel in 2017. We have a very small house, and so every square inch counts. Nadja worked with me diligently and creatively to problem solve the space issues and fine-tune the drawings. She worked collaboratively with the builder, making the project go more smoothly. No project goes perfectly, but when we discovered an error, Nadja was 100% principled about it and made it right -- this is a rare and invaluable trait for a consultant! I highly recommend Nadja's work. **★★★★★ — Andy Vella, Nov. 2018** > Nadja was great to work with and incredibly knowledgeable about all aspects of the project. She helped us make decisions in a cost conscious manner while also advocating for making the best decisions to achieve our desired results. Would absolutely recommend working with her! **Comment from Knocknock:** > Andy > Thank you so much! > It was a pleasure working with you! I hope everyone is doing well! > > Sincerely, > Nadja **★★★★★ — Massimo LoPorto, Oct. 2018** > Nadja did an excellent job with my kitchen remodel! She was super helpful in creating the entire plan, from the size of the appliances to adding special pull-out drawers. Her enthusiasm and expertise were a huge asset to my first remodel. I would highly recommend her for your project! **★★★★★ — Teresa Stout, Sept. 2018** > I have been following Nadja's work on Houzz and love her style! After running into roadblocks with my own kitchen design project, I decided to reach out to Nadja on the Houzz message board and ask for advice. Honestly, I never expected a response since the question was not regarding her project. Imagine my surprise when not only did Nadja reply within 24 hours, but she sent me such a detailed and thoughtful answer to my question, that it has helped me get over my hurdle and I am now able to move forward with my project as I had hoped. Nadja is a true professional and I am so thankful for her input! **Comment from Knocknock:** > Thank you so much! Best of luck with your project! > Sincerely, > Nadja **★★★★★ — sharon tringali, Aug. 2018** > Knocknock's designer, Nadja Pentic is a rock star is her field! Nadja helped me through every aspect of my kitchen remodel, even when things got difficult with my contractor. She truly understands that a remodel can be stressful and believes that it is part of her job to help reduce that stress when she can. From the overall design to the small details like hardware and lighting she was there to support and guide me. She stands behind her work 100% and her work ethic defines integrity. Nadja's style is relaxed, collaborative and always professional. It was a pleasure to communicate with her. I am so happy I found her and hope to work with her again. Thank you so much Nadja for the hours of hard work you spent, so that I could be truly happy with my new kitchen. You truly do rock! **Comment from Knocknock:** > Thank you Sharon! It was a pleasure to work with you! **★★★★★ — Mandala Feng Shui SPACE AS Medicine, Feb. 2018** > Nadja Pentic knows her stuff. My work is Feng Shui and Nadja is also open to incorporating Feng Shui design principles into her designs.. If you need an expert to recommend not what is trendy but what makes sense for your lifestyle and homestyle, she's insightful, intelligent & thoughtful in creating your dream kitchen or bath for your budget. I work with many different clients and always know that when I refer Nadja, my clients will be happy. referred her to a long time friend in Danville and he is over the moon with the results, she did a gorgeous job and I was impressed at how high end the finishes were but not the price tag! **★★★★★ — PROYECTO, Aug. 2017** > Nadja and Knockknock are your one stop shop for kitchen design. We have worked with her on several projects and each time she has made the job very easy. She provides excellent layouts, always responds to customer needs, and is extremely fastidious about cabinet fitment and timing. I would trust any size project to her. Your kitchens will be stunning and done on time! **★★★★★ — Noelle Pillsbury, June 2017** > I highly, highly recommend Nadja! She has a great design eye, is very knowledgeable, really listens to you, is easy to work with, very efficient, has a good sense of humor and is very reasonable. > > Before I hired Nadja, I was trapped with a design that I didn't love and felt I was always being talked out of my concerns. A friend who had completed a big home remodel project recommended Nadja. Nadja listened to what I wanted, drew some quick sketches of several options that totally made sense - and snap, I had a design that my husband and I both loved! She helped complete our color palette, our tile pattern and tiles, paint, lighting placement and so much more. Nadja didn't push options that were over our budget and in fact had a lot of suggestions that saved us money without sacrificing quality or style. Nadja is a walking encyclopedia of knowledge and ideas so she is fast (an hour with her is like two hours with someone else), but she's very warm and not pushy. And importantly, our contractor had fun working with Nadja too. > > Whether you have a large project or just want advice, I definitely recommend Nadja! While she was working on our project she helped my friend pick out a front door color and gave another friend advice and sources for a rental house kitchen remodel. Thanks Nadja! **★★★★★ — Mike Schmiedt, May 2017** > We had a great experience working with Nadja. Not only does she have a great eye but she is a fantastic communicator who is very responsive and accountable. The kitchen we ended up with was better because of her and we are very happy with the final result. I would recommend her without reservation! **★★★★★ — Arcson Design, Oct. 2016** > Nadja and I have collaborated together on multiple projects her knowledge in design and actual application has made put her on the top of my list of colleagues to work with when designing and building out my projects. In addition Nadja's attention to detail and skillful knowledge of custom cabinetry are an added bonus to her complex and crafty process. **★★★★★ — Lifestyle Color Consulting & Decorating, Aug. 2016** > I am an interior designer for all areas of the home except kitchens and baths. Whenever I have a client who needs great design for kitchen and bath, I call on Nadja from Knocknock. > > She is very talented, sensitive to customer needs and does everything possible for the customer to have great results - every time! > > I have complete confidence in Nadja and will continue to refer her whenever possible. > > I will be using her services on future kitchen and bath projects in my own home. **★★★★★ — Barbara P, March 2016** > Nadja was a breath of fresh air in a very long and complicated house repair and remodel project. Our architect recommended Nadja to help in the kitchen design and she exceeded all our expectations. She had a great eye, worked seamlessly with our general contractor, cabinet fabricator, and architect. We had a vision and she helped us realize it, identifying all the problems that we didn't anticipate and providing thoughtful and sophisticated solutions to every design issue that came up. Although we knew she had a lot of experience with modern European kitchens, her overall knowledge and expertise in design and functionality served us well in our Mediterranean kitchen. Nadja was very responsive, communicated well, was very cost conscious, and this was the only part of our project that came in on time and on budget. She said to us "This is your kitchen; where you will have coffee every morning, so it should be what you want it to be." It is all that and we love it! Thank you, Nadja! It was wonderful to work with you and we give you our highest recommendation. **★★★★★ — mcochrane95, Feb. 2016** > We hired Nadja Pentic of Knockknock to work with a designer and general contractor on a large foundation repair, house releveling, and remodeling project. Nadja was recommended as the Kitchen consultant, and she was superb in all aspects of her job. She has a wonderful eye, and is very knowledgeable about kitchen appliances, cabinets, countertops and layout. Nadja listened very carefully to how our family uses the kitchen, and came up with a design that works beautifully. She didn't discount our ideas, but refined and honed them, along with adding her own design details to ensure the kitchen worked as we wanted it to. Nadja was responsive, on time, and on budget throughout the project. She was a pleasure to work with, and we give her our highest recommendation. **★★★★★ — Alexis Haselberger, Feb. 2016** > Nadja (aka Knocknock) was amazing to work with. Not only are her designs very modern, but she is also focused on creating a livable kitchen for your family's needs. She was super straightforward, which I loved and very easy to work. She was able to accommodate our schedule, meeting in the evenings after work. > > She met with us to get a feel for our needs, then prepare about 5 separate designs. We refined from there and the process was easy. > > Best of all, we now have a totally amazing kitchen that is very easy to cook in (I cook 3 times a day) and has a place for everything, so it always looks clean. I would hire her again in a heartbeat and have already recommended her to friends. **★★★★★ — jpass7480, Feb. 2015** > Nadja did a phenomenal job in designing and creating our new kitchen. She listened to our wish list and created a clean and modern kitchen within our budget. Throughout the process, Nadja offered design elements that we had overlooked and she provided detailed computer drawings of the proposed kitchen. She is a pleasure to work with and I wouldn't hesitate to use her services again in the future. Highly recommended! > > Thank you!! **★★★★★ — Amanda Caudle-Larkin, Feb. 2015** > We worked with Nadja on a cabinetry for a kitchen and office rebuild after a fire destroyed our home. Obviously, in such circumstances, you are in a lot of shock and making all kinds of decisions at once, and it is easy to get overwhelmed. I think we would have been much more overwhelmed without the advice and guidance we got from Nadja. > Nadja was truly awesome to work with. She listened to our vision, adjusted the plans as necessary when what we wanted wasn’t practical, and gave us great advice even if it went against what we were picturing. She was able to listen, but still wasn’t afraid to tell us when something wouldn’t work or there was something that worked better (for example, reducing the size of our planned island, moving a pullout higher or lower). If we weren’t sure, she showed us in person or marked with tape what she was suggesting. And on every single recommendation, she was right. As a result, we got two EXTREMELY functional, beautiful spaces that fit seamlessly into our home. > Installation went with relatively few hitches, and any issues were resolved quickly and painlessly. Her installers were happy to work around our contractors to get things done quickly and correctly. In the midst of a pretty difficult experience, our work with Nadja was easy. **★★★★★ — Jamie Gold, CKD, CAPS, MCCWC, Jan. 2015** > I brought Nadja in on two Northern California projects and was totally impressed with her on both! Most recently, we completed a kitchen/study project in the Davis area together. Nadja handled all of the measuring, shop and plan drawings, ordering and install management. She is detail-oriented, knowledgeable, delightful to work with and totally responsive, (even when last minute details arise, and even when she was on vacation out of the country!). > > I look forward to working with Nadja again and would be glad to speak with any prospective client or professional about her. **★★★★★ — SHARON Stone Design Build, Nov. 2014** > Don't look any further. I know Nadja for many years but every job is like the first time. So happy and exited to work with her. > She is a hard working business owner and kitchen designer. Very professional, knowledgeable and creative. > It has been a pleasure working with her for so long. we both very committed to our projects and clients therefore we understand each other very well. > She strive to bring her clients the highest level of professionals and yet she likes to be involved in every phase and detail in the project just to make the process easier on her clients. > Wonderful and amazing person to work with!!!! Always a pleasure to work with you my dear! **★★★★★ — janellevanr, Nov. 2014** > Nadja provides high quality kitchen and bathroom cabinets. She is very knowledgable about her products and the best way to put a kitchen together. In addition to measuring and laying out our cabinet design, she was able to help us select hardware and countertops that made the whole kitchen work together. We are very happy with the result. **★★★★★ — jaielleo, Nov. 2014** > I would highly recommend Nadja! My architect had drawn up the floorplan for my new kitchen, but we were definitely on different pages as far as style. I had a general vision, but it was time to get down to the details. Enter Nadja Pentic. When she met with me for my initial consultation, I was happy to see that her portfolio looked just like my idea binder, and I knew we would be on the same page going forward. There were, of course, many, many, many decisions to make, and Nadja helped guide me through it all. Nadja often narrowed down the choices for me, but because she knew I wanted to see all the options, she also left me with binders and samples to consider, so when I made a decision, I felt confident with my choices. For me, it was the perfect collaboration. I felt listened to and guided at the same time, and ... I love my kitchen! One of the comments I often get is that it looks very "me" -- and I will take that as a compliment! Thank you, Nadja, for giving me my dream kitchen. \[piedmont remodel/black/white/grey kitchen\] **★★★★★ — jenlevdoucette, Nov. 2014** > We had the most wonderful kitchen remodel experience with Nadja. On-time and on budget. Nadja communicates clearly and is always available to answer questions or go over details - her attention to customer service is just one of her many attributes. Understood our space limitations and designed the most efficient use of the space, as we incorporated a 3-person workstation into our kitchen area. She also understands realistic lifestyle uses of space - especially if children are involved in the mix. We had several different contractors involved on-site, and Nadja was able to effectively manage communication among everyone. She will be the first person we contact for our next remodel project. **Comment from Knocknock:** > Thank you Jen! It was a pleasure working with you! **★★★★★ — hillarymilks, June 2013** > Nadja was able to walk into our kitchen and dining room and immediately come up with great ideas for re-doing the entire space. She explained her process thoroughly, which was helpful for us novices, and she was always easy to talk with through out the entire process. We wanted a more "transitional" style than her usual modern style, and she was able to help us with design elements that worked for us. We loved that Nadja will share her opinions with you - we wanted her expertise, but she is flexible enough to work around any specific elements you really love. We hope to work with Nadja again on additional projects, and we highly recommend her. ## Selected projects - [Warm Modern Walnut Kitchen Remodel](https://www.houzz.com/hznb/projects/warm-modern-walnut-kitchen-remodel-pj-vj~7881361) - Location: Oakland, CA - Photos: 14 - [Light-Filled Modern Kitchen in Orinda](https://www.houzz.com/hznb/projects/light-filled-modern-kitchen-in-orinda-pj-vj~7817380) - Location: Orinda, CA - Photos: 20 - [Transitional Home Remodel in Danville](https://www.houzz.com/hznb/projects/transitional-home-remodel-in-danville-pj-vj~7819695) - Location: Danville, CA - Photos: 34 - [Soft-Neutral Modern Kitchen in Orinda](https://www.houzz.com/hznb/projects/soft-neutral-modern-kitchen-in-orinda-pj-vj~7675866) - Location: Orinda, CA - Photos: 17 - Description: A Calm, Refined Space with a Fully Integrated Luxury Appliance Suite This Soft-Neutral Modern Kitchen in Orinda is designed to bring together quiet elegance and high performance.
