Bill was founder and coordinator of the Subcommittee on Renewable Energy and Sustainable Design for Boston Harbor Islands National Park Area. Since leaving his practice of gastroenterology and hepatology at University of Massachusetts Memorial Medical Center, much of his time has been directed toward promoting sustainability with respect to natural resources and ecosystems. He and his wife spent several months a year in volunteer capacities in Guatemala. Bill holds a BA in philosophy from Bowdoin College and an MD from Boston University. His current work actively relates to 350Mass in its effort to combat climate change and, for therapy, continues to maintain the community orchard he started in 1992.
