Mill is the Executive Program Director for Reef Relief based in Key West. Growing up along the shores of the Chesapeake Bay he learned early on of the importance of healthy watersheds. This led to an 18 year service working with Clean Water Action in Baltimore that continued onto the Tampa area. Over that period he worked on dozens of water quality related campaigns as well as helping to bridge a collaborative coalition building effort with the Chesapeake Bay Foundation. He was also the lead organizer in CWA’s campaign partnership with the AFL-CIO Working America to establish new offices in several US cities.
Mill has spent over 6 years running Reef Relief’s programs to educate and activate people around coral reef ecosystem conservation, specifically in South Florida. He has served as a member of the Monroe County Port Advisory Board and is an advisor to Reef Relief Board members serving on the Florida Keys National Marine Sanctuary Ecosystem Protection: Ecological Reserves, Preservation Areas and Wildlife Protection Working Group and the Higgs Beach Redevelopment Committee. On behalf of Reef Relief, Mill also manages the Key West Marine Park in collaboration with the City of Key West and Monroe County.
