Bill worked primarily with non-profit groups focused on energy and natural resource development that threatened endangered but intact ecosystems and working ranchlands in the Northern Rockies, western Canada and Alaska. Traveling regularly throughout the this region, he helped link groups together, encouraged strategic thinking about their work and advocated for their financial support. Over the years, Bill worked on both sides of the foundation desk, seeking to leverage support for grassroots and regional groups working on environmental stewardship, social and economic justice and nuclear safety. He was an advisor to the Alki Fund at Tides since its inception in 1991. Bill was a founding member and a Carpe Diem West core team member from 2007-2016.
