John Marks founded Search for Common Ground (Search) in 1982, at the height of the Cold War, to build bridges between the US and the Soviet Union. Operating from the basic belief that the world is running out of space, resources, and recuperative capacity to deal with wasteful conflict, he built Search into one of the world’s largest nonprofit organization dedicated specifically to ending violent conflict. Prior to founding Search, John served as a Foreign Service officer, as lead staff to Senator Clifford Case, and co-authored bestselling book, The CIA and the Cult of Intelligence. John is Visiting Scholar in Peacebuilding and Social Entrepreneurship at Leiden University in the Netherlands, an Ashoka Senior Fellow, and a Fellow at Harvard's Institute of Politics and a Visiting Scholar at Harvard Law School.
Susan Collin Marks joined in 1992 as Senior Vice President of Search and helped stimulate its major expansion throughout Africa, the Middle East, Europe, Asia, and the U.S. A native South African, she worked as a peacebuilder during her country's transition from apartheid to democracy. For over 20 years, Susan has facilitated dialogues and offered one-on-one coaching for political, institutional, and civil society leaders worldwide. In 2006, she launched Search’s Leadership Wisdom Initiative. She serves on multiple boards, including the Advisory Council of the Woodrow Wilson International Center Project on Africa and Leadership, and the Abraham Path Initiative. She was portrayed in the PBS documentary Peace X Peace: Women on the Frontlines. Her honors include a Jennings Randolph Peace Fellowship at the United States Institute for Peace, the Institute for Noetic Science's Creative Altruism Award, and an Honorary Doctorate from the University for Peace in Costa Rica.
In 2014, John and Susan transitioned into Advisory roles, handing over leadership to Shamil Idriss, who has been engaged with Search for over twenty years.
