His crew of professionals, electrician-plumper-painters were all top notch. > Joyce work very closely with the crew to make sure were getting what we wanted. If there was a problem she fixed it. She kept us informed and always returned our calls. We made numerous changes and she was always very patient. > We needed a experienced professional with lots of patients and the ability to make sense of our ideas. > Joyce is that and much more!! **★★★★★ — J T, March 2021** > We engaged Joyce to assist us with furnishing and accessorizing our new home. She was incredibly accessible as we went furniture shopping. She helped us envision how a couple different concepts could work. She made the the process easier by selecting sample fabrics, delivering those to us, and returning them. The same process was true for our rug selections. She helped us combine different styles and preferences. When some (most) of our custom furniture arrived damaged, she worked with the furniture store to make sure the issue was remedied. She did a great job of introducing us to quality professionals to help with painting, wallpapering, and carpeting our rooms. We are so happy with the finished rooms, and appreciate Joyce's help in making our house feel more like home. **★★★★★ — Shauna Rittenhouse, March 2021** > We have commented on multiple occasions how much the new kitchen has helped us manage our new pandemic realities. With both parents working from home and three children schooling from home the kitchen has become the true hub of the house. While we did not add any square footage on the renovation, the removal of a wall has afforded the space to function in multiple ways that would not have been possible before. Simply put, we couldn't be happier with the remodel. **★★★★★ — Shirley Henderson, March 2021** > Joyce was great to work with for the design of our new Bakery front. She listened to our ideas and came back with a plan of choices and reasonable pricing. She was flexible to make changes and offer new ideas. Would recommend her design services and use again as needed. **★★★★★ — Robert Rozen, April 2020** > We really enjoyed working with Joyce to update our main level. The space is relaxed but elegant, and we use it every day. The upgraded lighting really showcases our art collection. Our favorite part of the room is probably the gas fireplace. We use it so much more than the old wood-burning fireplace, and it also provides a lot of warmth, really cozy all winter and during the chilly spring evenings. I love how Joyce helped to make it uniquely ours, helping us define our style rather than imposing hers. She really streamlined and facilitated all aspects of our project, hand delivering samples and making style recommendations, as well as coordinating contractors and workers. She saved us a lot of time and effort by doing the legwork, and the results were worth it! **★★★★★ — Paint Imagery, Jan. 2018** > I have been a subcontractor of Joyce's for many years. Her projects are always unique, well scheduled and her joyful personality makes each project a delight. Her clients always tell me how much they enjoy working with her. Sincerely, Susan Greene/Paint Imagery, llc. **★★★★★ — Sherry Fletcher, Jan. 2017** > I have been working with Joyce for ten years. I am a cabinet salesperson > and we work on some of the same projects. Joyce always adds great ideas. > Her goal is that the customer will be happy with the end results and > enjoy the process. She is a joy to work with. I would definitely recommend > her for your project (big or small). **★★★★ — Cheryl Adler, Jan. 2017** > I found Joyce to have a lot of energy and full of ideas. I let her know what I was thinking and she ran with it. She is very prompt and has contacts for anything you need. I enjoyed working with her and am very pleased with the results. I reupholstered two love seats and two chairs and window treatments **★★★★★ — Randee Wahlgren, Dec. 2016** > We had a great experience with Joyce. She listened to us and made suggestions based on our answers and budget. Joyce incorporated some of our existing accessories whIle also finding affordable rugs, window treatments, and lighting that worked beautifully. It was an absolute pleasure working with Joyce and we highly recommend you give her a call. **★★★★★ — Plumbing Haus, Dec. 2016** > Plumbing Haus has done several projects with MJM Design Company (Joyce Mathis Owner), most recently we did a very custom Heavy-Glass French-Doors shower project. These doors were to be the culmination of an incredible His & Her thermostatic spa shower. This project required several design meetings with Plumbing Haus, the client and Joyce. Joyce came fully prepared to each meeting, helped the client convert their vision to a workable project, then shepherd the project along by establishing timelines and keeping all parties fully informed. At one point, the owner need materials that were stored in the home moved before they returned from out of town. Without hesitation, Joyce marshaled the help needed to move these items and make the space ready for her client’s return. Not the usual task associated with a Designer. > > I have worked with Designers who have great visions but do not know how to make the visions a reality. I have worked with Designers who are great organizers but don’t challenge convention in their designs. With MJM Design, you get the whole package. I recommend MJM Design Company without reservation. > > Sincerely, > Robert Lay > General Manager, Plumbing Haus **★★★★★ — Dayl FULLMER, Oct. 2016** > Joyce is the ultimate professional. She is quick to respond, current with trends and information and completes her projects with happy clients. From a fabricators point of view, her knowledge and experience makes the project move along smothly. As and added bonus, Joyce has great energy and is fun to work with. **★★★★★ — Anne Matheis, Oct. 2016** > I have worked with Joyce for over 10 years, photographing her design work. Joyce is great to work with! She has an amazing relationship with all her clients. She is so good at communicating her thoughts and listens to her clients needs and wishes. She is professional, talented and creates spaces that are interesting and inviting. **Comment from MJM Design Company:** > Thank you Anne. As I have told you over and over, we work so well together! Looking forward to many more projects! ## Selected projects - [Master Bath Serenity...Asian Style](https://www.houzz.com/hznb/projects/master-bath-serenity-asian-style-pj-vj~2669899) - Location: Saint Charles, MO - Photos: 12 - Description: In her "well-thought out" 10' x 13' Master Bath, my Client desired specific items to give the sense of calm she relished at the end of a demanding business day... -Heated free-standing tub with air jets -Steam shower with aromatherapy, and, included for mood music, built in speakers -Privacy for toilet area -A special furniture piece to serve as the vanity base -Privacy between the vanity and the free-standing tub Then the layering of textures, colors, objects...

Would love to know name and manufacturer of paint color. It serves as a perfect neutral, warm backdrop. A: Thank you for your kind words! The wall paint is Benjamin Moore's Cosmopolitan \#CSP-100. **Q: flooring** *(in Photo Questions)* what is this floor? how do I look up the source? A: US Floors: Bamboo Plank in Java. Thank you for your interest! **Q: Flooring?** *(in Photo Questions)* Wow, great job! Can't believe that's a basement. What is the flooring used here? Also, was it installed over a subfloor (like Dricore) or directly on slab? A: I have not received any negative comments from my Client on this product. This luxury vinyl plank product is somewhat more than SOME carpets as a start up cost. Since it is very durable, I feel the initial cost is well worth it! **Q: How do I find this faucet?** *(in Photo Questions)* A: Delta's Cassidy in Venetian Bronze **Q: Countertop** *(in Photo Questions)* What is the countertop material and color? A: Hi! the island counter top is Wild Sea Green granite. **Q: what are the pillars made of?** *(in Photo Questions)* what are the pillars made of?
