Join John Marks, the founder and long-time president of Search for Common Ground, as he speaks about how he and his wife, Susan Collin Marks, used the methodology of social entrepreneurship to create the world’s largest peacebuilding organization — with a staff of 600 and offices in 35 countries — and earned a nomination for a Nobel Peace Prize in 2018. Included in the presentation is a short video, demonstrating how a flexible, opportunistic approach led to breakthroughs in resolving conflict on a societal level and producing media for social change in such places as the Soviet Union, Iran, Burundi, and the Democratic Republic of Congo.
