About Us

Remodeling and Home Design

Very organized in the company's scheduling and organization with subcontractors. Very accommodating and assisted me in decision making as far as granite, cabinets, flooring, etc. He still owes me a lunch though!! Great company. I will definitely use them in my future remodeling projects.​


Lynne J. Petaluma,


As a past customer, I highly recommend Jeff Dean. He designed kitchens for two of my houses, and I am very pleased with his work. Jeff is very professional, and he was honest and up front about everything. He was very timely and treated me as more than just a client, and more so as a friend. I had absolutely no problems with Jeff, and would use him again. My kitchens turned out beautifully. They are so much more than I ever imagined, thanks to Jeff.
