Donald Mosier is the newest member of the San Dieguito River Valley Conservancy (SDRVC) Board. Donald is professor emeritus in the Immunology and Microbial Science Department at the Scripps Research Institute, having recently retired after four decades of HIV-1/AIDS research. He also brings with him a long history of community service, including his service as the mayor of Del Mar from 2010 to 2011, a two-term City Council member, and a member of the Design Review Board. “I am pleased to join the board to help protect and complete the Coast-to-Crest trail and to provide more recreational and educational opportunities for all of our citizens,” Donald shared.

“I’m very pleased to have Don as a member of the Conservancy’s board,” said SDRVC Board President and Rancho Santa Fe resident Peter Shapiro. “His public volunteerism is exceptional and his experience as a JPA board member is a natural fit to now work with the Conservancy, the JPA’s key partner.”

Founded in 1986, SDRVC is a nonprofit organization dedicated to preserving, protecting, and restoring natural and cultural resources within the 55-mile-long San Dieguito watershed. The group, along with its partners, has been successful in acquiring and assisting in the funding of thousands of acres of land, restoring hundreds of acres of habitat, and providing recreational activities and environmental education to the greater San Diego community.
