Diana was a delight to work with on my kitchen remodel. She was responsive and involved from start to finish. Diana is professional, warm, and friendly which made the difficult process of making important decisions manageable for this wishy-washy human. She took the time to get to know me and my design preferences so she could help steer me in the direction of cabinets, countertop and backsplash I absolutely love. When obstacles arose, she was understanding and calmly made adjustments. Diana worked beautifully with my choice of contractor, electrician, and plumber. Her recommendation for a tile person was very much appreciated and he did an exceptional job. I have nothing but highest praises for Diana and am so grateful for her creativity and vision that have provided me with my dream kitchen.

We recently added an ADU/Guest House and did a series of upgrades to the main. From paint colors, to furniture, to custom art, Diana has been a valued partner all along the way. She understands our style preferences as well as our overall vision. She also has good connections in the interior design community which have proven invaluable. She also has been very proactive in dealing with any issues that come up. We enjoy working with her and would recommend Diana without any reservations.

We have worked with Diana on multiple projects including a major kitchen redesign and two bathrooms. Most recently she helped us upgrade our master bedroom with new flooring, rugs, accessories and a spectacular new closet. Very cost effective and we found many of the items online in a matter of hours. Diana identified the concept of a hanging headboard which I had never heard of but worked perfectly and along the way helped us out with a recommendation for a kitchen range when ours needed replacing and we were having trouble finding something. She is truly enjoyable to work with.

We have worked with Diana on several home projects, including three bathrooms, a kitchen update, paint and flooring and we were so happy with the results. Before working with us, she interviewed us to learn about our style and budget. Diana is efficient, creative and listens to her clients. We appreciated her researching products that were elegant and yet were within our budget. Her follow-through is excellent. We especially appreciated her willingness to be open to our ideas. She really "got" us and our style. Diana is really easy to work with and we highly recommend her!

Thank you Regina! I've loved working with you and Doug on your home over the years. I love your primary bathroom update, as well as the bedrooms. New flooring, interior paint, updated ceiling fans and your custom cabinets really take your home to a new level of enjoyment! Your colorful art looks amazing in the house! Thank you for having me as your Design Partner!

Diana was incredible! A life saver! She jumped in on a tough project - helping us redesign my childhood home in Davis while we lived across the country in New Jersey - and under a very tight timeline worked with our contractors, sourced excellent materials to fit our budget, helped us pick furniture, etc. and had us move in ready in less than three months!
Diana is not only very responsive but also proactive and thoughtful, with great taste and good connections and industry discounts available to her. We can’t recommend Diana more enthusiastically!

Thank you Kelly and Jim! I think it's safe to say we nailed "working virtually". I so appreciate the trust you had in me to take care of your remodeling project long distance. Your childhood home is now ready for the next generation of Monagles! Best wishes always!
Diana was great to work with on the remodel of our primary and guest bathrooms and with advising on the overall interior design throughout our house. She brought design expertise and was very knowledgeable about the process and assisted in managing the work and explaining the timing/steps along the way. She brought creative ideas that we would not have thought of and we love the finished project. We highly recommend Diana and hope to work with her on future projects.

We give Diana Mahoney the highest recommendation possible. We have had the opportunity of working with several decorators/designers in the past, and she rates at the very top. She has helped with a complicated remodel of the house we just bought. A good portion of our house has been updated and remodeled, and the project will be finished soon. She has helped us design a brand new kitchen, remodel the master bathroom, choose and replace all the flooring and window coverings, and update the house in general. She has wonderful professionals who she recommends to do the work and we’ve only had top quality work done by all of them. She has also assisted with any problems that are inevitable in a remodel and immediately addressed them to our complete satisfaction. She always listens extremely well to our needs, and easily pivots off her previous suggestions, as she learns more about our preferences and living style. She has always addressed our specific needs with ease and patience. Never once have I felt she was frustrated working with us, even though we changed our minds many times on the project. Remodels are notorious for being extremely stressful. But, Diana has actually made it fun to a large degree. We cannot give her a higher recommendation!

Susie and Mark, Thank you for these kind words! Your feedback means the world to me. Your project has been a marathon, not a sprint - and the outcome has been so satisfying! Thank you for your trust and endurance as we navigated many challenges during your renovation. Furniture deliveries are around the corner!!! With gratitude, Diana

Diana helped me with multiple projects big and small since 2019. From remodeling our kitchen to remodeling our guest bathroom, and changing our front door. Working with her is definitely a game changer. She saves me from making any design mistakes. She is like the fairy god mother of home improvement. I trust her so much that by now I pretty much just tell her what our project is, what I'm trying to achieve and then ask her to tell me what I need to buy and then she uses her magic wand and everything just looks amazing. She is very talented and super easy to work with. Her professional fee saves me money in the long run because it gives me peace of mind that I am making the right choices. I used to think I am good at decorating my house but when I met Diana, I realized that having a professional help streamlines the whole process and makes it less stressful, and even much more fun.

My wife and I have used Diana for multiple projects, large and small. Diana is always great to work with. What has made Diana so valuable, is her overall design and project knowledge. Diana knows what the best stores are to buy from, making sure we kept design style (faucets matching shower heads, oven style matching fridge, etc.) consistent. For our kitchen and bathroom remodel, Diana helped us pick out fixtures – what would have been a long and not so fun task, Diana made it efficient and easy – no overthinking of the process. When thinking through a project, Diana can suggest alternatives that save a client money without sacrificing the finished look. In addition, Diana has a deep bench of contractors and trade professions that have been wonderful to work with.
At the end of the day, Diana is fun to work with, efficient in her project planning and can guide clients to design solutions that will leave the client extremely happy. I have recommended Diana to multiple friends and family without any concerns. We are looking forward to our next project with Diana!

Diana is in a league of her own! We had purchased a home that we knew needed some upgrades, and really did not know where to begin. We interviewed a few designers, and instantly fell in love with her knowledge, expertise, demeanor and ultimately my husband and I felt we could work well with her. That should be enough, but the product she delivered, her adherence to timelines, her flexibility and follow through was phenomenal. She has such an incredible eye, and was able to hear what we were seeking and provided both depth and breadth of choices. We will only use her in all future products, and give her the highest possible rating.

I am so thankful that we used Diana from the The Design Partner in our recent remodel! She made it all happen in record time with amazing results. She has a wonderful eye for color schemes, as well as furniture and accent pieces. She was a pleasure to work with as she has amazing suggestions from flooring to backsplash and appliances. She met with us in person to help pick items or would source them for us with multiple online suggestions making it easy to mull over and decide. Her connections to quality vendors with great pricing had us completing this remodel of our entire downstairs with very little stress. We know we could never have done this on our own. I would highly recommend Diana to anyone as her calming presence combined with expertise and experience made this whole experience a good one!
