"What started as a consultation on wood flooring stain colors, turned into a total house transformation and new friendship. Diana was able to quickly see what updates were necessary to refresh our beloved home. She listened to our needs and helped us “see” how our home could elevate to a new level. There were a myriad of choices and decisions, and Diana presented each step thoughtfully with intention. Diana is a design partner and I felt in control of what I wanted for my house with her guidance. Diana’s experience with vendors and resources allowed me to maximize my investment and procure high quality materials and furnishings. I hold Diana in my highest esteem and would recommend her without hesitation to anyone preparing to remodel their home.”
K. Jelks, Davis
“Diana is an outstanding resource and design consultant who has worked with me on several projects, from house painting to kitchen remodel and bathroom remodel. She has superior design and aesthetic sensibility combined with pragmatism and logistical management skills. She is responsive and available, and works with you on your own ideas as well as offering her own, willing to step in as much or as little as you need. Diana advises honestly. She also has valuable connections throughout the remodel industry that have enabled me to get what I needed at the best price. Importantly, the outcomes have been superb - I love the results! Strongly and enthusiastically recommend.”
M. Christopher, Davis
“We have worked with Diana on many projects over the years, some simple and some more involved. Each time she has been very professional, timely and always stays on budget. She works hard to find the best deals so you get the most for your money. In our family room redesign, Diana was able to reorganize our existing furnishings in an updated way which saved us hundreds of dollars. Diana has a special knack coordinating color, space and layout. She is always helpful whether you have a quick question or need an involved design layout. Diana is fun, easy and enjoyable to work with. We would highly recommend her to anyone.” The Thompsons, Davis
“Diana’s creative ability and energy, calm confidence, and knowledgeable professionalism combine to make her an excellent choice in design help. She has gone above and beyond in helping me choose elements that reflect my style and sensibilities. Her thoughtfulness in incorporating sentimental pieces into the overall design is very appreciated. I give her my highest recommendation.”
K. Doty, Davis
“We have worked with The Design Partner for two major remodels. We have been very pleased with her insight, her timeliness, her ability to listen and to help us winnow a vast number of options into just a few in short order. Help with colors was especially important. Our calls and emails were returned promptly. We understood what everything was going to cost. And we enjoyed our interactions."
A. Bridge, Davis
“While I can recognize good design when I see it, I am not the kind of person who can research options, compare details, and make multiple selections that blend seamlessly and create a theme. Diana does this. Her warm, understanding style of listening and communication made the remodel of our kitchen, and years later our bathrooms, and then our dining room very easy. I really appreciated her ability to move the projects forward when I wanted to stall with indecision. With her guidance, I have a lovely, updated home with thoughtful, attractive and functional design.”
D. Welch, Davis
"Diana helped us through a pretty extensive remodel of our Wildhorse home. She was so helpful in getting the ball rolling on a project that had been in the planning stages for quite a while. We really needed help in finding what our preferred basic style was and once she helped us figure that out, Diana worked with us through the numerous details involved in picking out colors, flooring, design details and finding the right people to do the work. She is very easy to work with and is a very talented designer!"
The Meyers, Davis
“Diana helped us with a kitchen, master bath, and kids’ Jack and Jill bath remodel, with an added bonus fireplace update with our remaining kitchen stone. We couldn’t have survived without her, and the results are gorgeous. Diana was there for as much or as little as we wanted, always respectful of budget and time management. Her combine

We couldn’t have survived without her, and the results are gorgeous. Diana was there for as much or as little as we wanted, always respectful of budget and time management. Her combined design ideas and industry contacts really made it easy and gave us much needed confidence to charge forward. We recommend Diana without hesitation!”
The Schroeders, Davis
“I have worked with The Design Partner on several projects over the past few years. Diana is always professional, responsive and has a great eye. When we encountered setbacks with materials, she is always calm and moves quickly to find a solution so our projects can continue to move forward. She is a wonderful resource for contractors and tradespeople in the area who can step in to complete small projects as well.”
D. Rubin, Davis
“Diana’s warm personality captivated our hearts as she transformed our ‘house’ into a cozy family home. Her appreciation of our family roots brought forth our personalities in our living space. Diana blended together a tasteful serenity of the Tucson desert along with a touch of Big Sur charm. She acknowledged our longing for warmth integrating beautiful and subtle earth tones, fulfilling our dream. Diana is our design partner; she is a dear.” The Bensons, Davis
"Diana Mahoney is my design partner.”
Chad DeMasi, Davis
“Diana is able to work easily between the seller and the Realtor. I appreciate her professionalism and expertise.”
Anita Dhesi, Davis
"It was such a pleasure working with Diana Mahoney to stage our home for sale. She came in with our agent and quickly started making suggestions. I barely noticed she was even taking notes until she sent me an email within an hour of being at our home! Diana's email detailed, room by room, what needed to be moved, changed or eliminated. It was simple to print her suggestions and go to work. Within two days I had my house in impeccable shape and I thought, maybe I don't even want to move now? Diana definitely has found her niche in this world and we feel blessed to have had her skills to make our house market ready."
The Halls, Davis, CA
“I had the pleasure of working with Diana Mahoney during the preparation stage of placing my house on the market. She came highly recommended from my realtor who had worked successfully with her in the past staging and decorating homes. Diana worked quickly, efficiently, on time and on budget to create a warm, welcoming retreat. Her professionalism and vision from start to finish made the entire process easy and even enjoyable. Her recommendations on paint colors, hardwood floors, carpet, and perfecting the final details that create the "important" first impression were right on target. My house was sold in less than three weeks during a very slow market. Diana exceeded my expectations. She has a natural eye for style and I can't wait to work with her on my own home!”
Dr. Kris Hansen, Manhattan Beach
"As a semi-retired General Contractor now specializing in interior millwork and cabinets, I can highly recommend Diana as the “ultimate source” for design ideas, colors, and overall design concepts. Her innate sense of color, blending and shading is amazing. I continue to be impressed with her ability to transform a vision into reality, no matter what a client’s design taste and wishes may be. We have worked together on many projects, and I have always found her to be gracious and professional. She is the best!"
Rich Hughes Construction, Novato
“Diana has impeccable design sense, style and savvy. She is also worth her weight in gold.

“Diana has impeccable design sense, style and savvy. She is also worth her weight in gold. I used Diana’s design services when my kitchen remodel-due to my own personal design choices-were sending me into a panic. She came in and saved the day..but not by blowing our budget or belittling my choices. She saw things my untrained eye could not. A change in wall color here, an update in hardware there-the end result: a classic, beautiful and pulled together look. Diana elegantly combines modern design trends with traditional design know how—you end up with a home or a room that will stand the test of time. That’s great design.
The Harrisons, Davis
“We have worked with Diana over the years on many decorating and remodeling projects and have enjoyed both the process and the results each time. Not only does Diana have a wonderful eye for design, she is also warm, enthusiastic, and a great communicator. She really listened to our needs and took the time to discover our vision for the spaces we were working with. Her ideas were unique, creative, fun, and within whatever budget we set. We also appreciated her honesty; we wanted her opinions, even when they didn't support something we had planned, and she was always quick to offer an alternative solution to any difficulty that arose. Diana is a wonderful design partner, and a joy to work with. We recommend her highly.”
The Kaplans, Davis
“Diana has been an excellent resource in helping me stage homes in preparation for being listed for sale. She is detail oriented and has an eye for proper placement for optimal showing. She has consulted with me on a wide range of clients’ needs from a house being flipped/resold to home that needs everything from paint, flooring to furniture placement. Diana is fabulous!”
Suzanne Kimmel, Davis
“Diana brought a great sense of style while really listening to me and blending her skills with my taste, living space and budget. I loved working with her, because she gently guided the whole process and had all the resources I needed to find what I loved. I really felt like I was working with a friend because she is relaxed, easy to work with and fun!! She really helped me bring all the pieces together to create a great space in my home.”
The Looneys, Davis
"As a REALTOR trying to prepare homes for the market, I love the way that Diana can walk into a room, squint her eyes slightly, take the whole thing in and instantly produce suggestions that will transform the space. Sometimes she merely moves a few pieces of furniture and some artwork, and the room suddenly feels opened and balanced. Diana is very talented and also a very sensitive listener. If you have an opportunity to have Diana Mahoney help you with your home, jump on it. You will be amazed.”
Jamie Madison, Davis
“When Diana entered our house, I could see that her "wheels" were already turning! She asked lots of questions about vision, functionality, purpose and style preferences BEFORE she made her recommendations. She really wanted to make our house something that was natural and comfortable to US. Her ideas about everything from designing and decorating, to de-cluttering have been so helpful. We are truly enjoying our home space now. Not to mention that we get lots of complements!”
The McGowans, Davis
"Diana updated and redecorated a condo that we were putting on the market in Davis, California.
She did a beautiful job, she has good contacts to get projects completed, and all while we were not in the area. She is trustworthy and honest and we highly recommend her for your next project"
