"I'm wired to build things," says David, who leads our Washington, DC office, "and the things I like to build require a group effort." With more than 25 years of experience, David focuses on solutions for base building construction, build-to-suit's, and mixed-use projects. He is particularly noted for his success in incorporating sustainable design into the mainstream commercial marketplace, and for his work rehabilitating older buildings, including one of Washington, DC's largest, the 2-million square-foot Constitution Center. "I've come to appreciate that great design ideas can come from anywhere and anybody," David remarks. "One of the great lessons is leaving yourself open to that." An encounter with jazz legend Dizzy Gillespie taught him a few nuggets, too. "He told me a lot about overcoming obstacles, rolling with situations, and expressing joy through music, and following your own path with dedication and levity."
