David Reed, Development Director

Growing up in Humboldt county helped David develop a close connection to wild places. He spent his childhood camping on the Smith River with family, hiking through redwood forests and fishing with his father, brother and grandparents in the rivers and mountain streams that define the redwood coast.

David’s work life has revolved around helping people change the world for the better and support the things they love through charitable giving. In the two decades before coming to Redwood Parks Conservancy, he worked as the head of development for a public radio station and in small town economic development.

David lives with his wife Cori, and two young daughters, Dani and Katie, just a mile from Fort Humboldt State Historic Park, one of RPC’s partner parks. He loves camping, walking and exploring some of the same places with his daughters that he experienced growing up here.

Joe is originally from East Tennessee, home to the Great Smoky Mountains. He arrived to redwood country in early 2019 and absolutely loves the beauty of the area.

Prior to finding his dream career with public lands, he spent over 21 years helping manage theme parks.
