David Warner is the founder and owner of Redhorse Constructors, a high-end custom home construction company in Northern California. He is also the CEO and co-founder of Elgin Energy Company, a geothermal development company in Northern California and founder of the Marin Agricultural Wind Co-op, a wind development charter whose mission is to provide locally produced energy to the Marin County energy grid. He received his undergraduate degree from the College of Natural Resources at the University of California, Berkeley in 1976 and his teaching credential in Biology from San Francisco State in 1977.

In 1981 David founded Redhorse Constructors. With a focus on sustainability and pushing the green building envelope, David has built Redhorse into one of the nationís premier custom home builders. In addition to a number of awards from the AIA, Architectural Digest, and local and industry organizations, in 2007 his efforts in sustainable construction and the implementation of green technologies in residential projects earned him the title Builder of the Year by the NAHB. As a result of Davidís fascination with new technologies and materials and his great concern for the environment, he has acted as technical advisor on a number of projects including Sir Richard Bransonís project for island development and sustainability and a green museum in Washington D.C. designed by Ken Kao and Sim Van Der Ryn.

In 2009, Davidís passion for music and commitment to his local community lead to his involvement with the Marin History Museum. He created a new format for the Museumís Music Center which included the production of a Metallica concert that set the stage for the endowment campaign.
