DP Design (Diane Plesset) helped to vision and bring into being the remodel of our Ocean house. She drew up beautiful virtual designs and blueprints, , knew all the best deals for quality materials, worked hand in hand with the contractor, helped us make decisions when we were stuck, and was always available for questions and brainstorming. Diane is professional and responsive, and always found us the best value. Were we to remodel again, she would be our first call. Thank you Diane and DP Design!

Hiring Diane was the best decision we made when it came time to remodel our kitchen. After listening carefully to what I wanted, she came up with a plan that more then met our needs. With her expertise, she came up with things that enhanced our kitchen more than I thought possible. Having Diane by my side reduced my stress level by leaps and bounds.

Her experience and desire to get me the kitchen that I wanted, eliminated my annoying need to research the heck out of everything because I had such confidence and trust in her abilities, knowledge and know how. Originally I came across Diane on Houzz by accident. I was so amazed by her before and after pictures, that I bookmarked her site on my computer for over 2 years.

I wasn't going to call at first because I thought that it would be too expensive to hire her. However I loved pictures of her work so much, I thought what's the harm in finding out. I am so glad that I made that call. Hiring Diane actually ended up saving me money after I subtracted her fee. If you're on the fence about hiring a designer, you should definitely call Diane because you have nothing to lose and a heck of a lot to gain!

Diane helped my husband and I get the kitchen of our dreams with increased storage and counter space, better lighting and efficiency, all without increasing the footprint. We didn't want a kitchen out of a catalog, but something unique to us. She listened to our ideas, and gave us practical, honest advice. Her design skills and product knowledge are the best.

Diane is absolutely passionate about home design. Her blog and podcast have been so helpful and informative as I consider everything I'd look into while buying and upgrading a new home. I am actually more excited about buying a house, knowing that I have so much information at my fingertips!

I have known DP Designs (Diane Plesset) since 2005. She has provided consistently great design that takes into consideration both form and function. Our clients enjoy working with her and our subs love the detailing she provides on her construction drawings. She also has a blog that offers a plethora of great information about remodeling, design and current trends. I can unequivocally recommend DP Designs as a premier designer who cares deeply about her clients and her designs.

Diane is fantastic to work with. She has outstanding passion for what she does, and it shows in the final project. She really takes the time to get to know you and understand your needs. I highly recommend Diane for any bathroom or kitchen projects that you are considering. Having the job done right from the start, will ultimately save you money in the end, and give you the finished project you've been dreaming of.

I have had the opportunity to see Diane's work and hear her present on several occasions. She is really a wealth of knowledge and the care she brings to each and every project in which she is involved is simply incredible. I know how much she cares about her clients, and I cannot say enough great things about her and her business. If you have the opportunity to encounter Diane or to work with her, count yourself as being very fortunate.

Holy cow! Diane is awesome! What I really appreciate is her deep knowledge of bathroom and kitchen design from all angles. You'll get not only a technically well-designed project, but one that flows well for your individual lifestyle. She literally takes everything into account in the design. And when it's done, it feels like you won a dream kitchen or bathroom on one of those awesome design shows on TV!

And it won't cost you an arm and a leg either. I highly recommend DP Design and Diane for your next home project. Be sure you take the opportunity to at least sit down and talk with her before you make any final decisions. You won't be sorry!

Diane Plesset knows her colors! I recently asked for Diane's advice before repainting and updating my kitchen. Diane brought samples and gave her expert advice, not only for that room, but also for how my choice would work with other colors in the house. You might say that Diane has a holistic approach to beautifying your home. I highly recommend Diane Plesset of DP Design. Thanks, Diane!

I have an 1896 farm house that needed a makeover. Diane worked with my ideas and added her own unique touches. She executed a beautiful design with basically the entire house remodeled inside and out. I depended on her knowledge for all the details I was ignorant of or did not have time to learn about. She amazed me with her expertise and kept it all on track.

If there was a question by the contractor I referred him to her and she took care of it. The project was completed in an organized and timely manner with no complaints from me. Her fees were very reasonable and she kept me on budget and focused on my priorities. Very personable service and always available

Diane was a pleasure to work with. She listened carefully to all our ideas and came up with a dynamic kitchen and dining room design that fit my needs completely! She never lost her cool even when I called her at the last minute and said I needed an under counter microwave on the bar. She simply said, “Let’s see what I can do” and she increased the size and shape of our smoothie bar to make it work! Her total design was beautiful and when friends walk into my house the first time, they usually stop, look and exclaim “Wow!”
Deborah M.
Diane listened well and provided creative suggestions, solutions, and alternatives during the time we worked on the design to remodel a powder room to create a full bathroom in my home. She left no detail untouched. Such thoroughness and professional know-how are an asset one does not find every day. I would gladly call Diane again for design services. She is very pleasant to work with — prompt, responsive, well informed.
D. & L. S.-S.
The design process for our new kitchen went very smoothly, and we appreciated D. P. Design's helpful suggestions and good judgement. We also appreciate the referral to the contractor, who was a pleasure to work with. The whole experience was positive, which is saying a lot because we've had a lot of trouble in the past.
M. & A. C.
Diane Plesset was wonderful. She listened to our concerns, outlined what we needed, and the project went more smoothly than we ever imagined. She maintained a close relationship with us and our contractor throughout the project, and we felt like we were in great hands. Our project was large, including two additions, and complete remodel of the kitchen, family room, and our master suite.

The project was completed on time and on budget, with only one change-order for a furnace that was due for replacement. She helped us to realize our dream of staying in our beautiful, contemporary, but too-small home in an idyllic neighborhood.
