Director of Programs

With an academic background in biology and philosophy, Dr. Marc Lucht worked as a professor and university administrator for 18 years. Before joining Clean Valley Council, he co-directed North Cross School’s first campus in China and led the development of additional high school campuses in Asia. Holding a PhD from Emory University, he has published widely on environmental philosophy, animal rights, and intercultural dialogue, and is strongly committed to the idea that it is incumbent upon humanity to find more responsible ways of acknowledging and living together with the creatures with whom we share the planet.
