Marin County Architect - Best of Houzz
Gregory Dedona founded his architectural practice in Mill Valley, CA in 1989 after receiving his California licensure. For over 30 years Greg has been serving local residents and project developers primarily in Marin County, as well as in the greater San Francisco Bay Area, Lake Tahoe, and Los Angeles. Greg's commitment to quality design and high level of thorough service has earned him a loyal client base and a reputation for ability and integrity. Throughout the years he has built a team of experienced professionals including civil and geotechnical engineers, land surveyors, and building contractors. Greg is a graduate of U.C. Berkeley, School of Environmental Design - B.A. in Architecture. His design philosophy is rooted in a contextual approach to each project site by shaping the client's program needs and fitting the design solution to the surroundings. He is not characterized by any one style, being adaptable to stylistic genres of traditional eras or modern contemporary influences. His abilities range beyond design, incorporating problem solving, management, and leadership skills into every project. Greg is committed to implementing Sustainable Design and Green Building practices in all his work. Greg served for over 12 years on the Tam Design Review Board, a planning review body appointed by the Board of Supervisors for the unincorporated Mill Valley areas of Marin County, and was Chair for nearly half his term. He is active volunteering in his community as a scout leader, and as a youth sports coach with his son and daughter. Gregory Dedona offers a wide range of architectural design and consultation services. Whether your needs are for full service project design and documentation from concept to completed construction, or simple construction feasibility consultation, Greg can provide all levels of service to suit your needs.
