Mark has been chasing the dharma since the early 1970s when he lived in Nepal as a Peace Corps volunteer, and eventually joined sanghas and studied with teachers in both the Zen and Shambhala Buddhist traditions. He has worked in the international health field for more than 30 years, including two long-term assignments in Vietnam managing assistance to war victims and other disabled people. It was while living in Vietnam in 2015 that he discovered One Earth Sangha online and immediately connected with the EcoSattva vision. Back home in Washington, he has helped One Earth Sangha organize local Buddhist community support for the People’s Climate Mobilization and recent climate strikes.
