David C. Harvey and Dawn W. Harvey, a husband and wife design team, established D&D Harvey Architects in 1995 after interning and working together since 1989.

The small firm, located in Sag Harbor, NY, designs and builds projects primarily on Eastern Long Island.  David, a graduate of the University of Miami 1989, and Dawn, a Syracuse University graduate 1991, are both licensed architects, each with their own diverse backgrounds.
