Mark Gerzon, president and founder of Mediators Foundation, has specialized in leadership that bridges divides. As an experienced facilitator in high-conflict zones, he has advised a wide variety of organizations including the US Congress, multinational corporations, and the United Nations Development Program. He is also a leading author of books in the field of conflict transformation, including A House Divided (1996), Leading Through Conflict (2006) and Global Citizens (2010).
His concern about the increasing polarization in America led him to devote the past three decades to working on the ideological frontier between Left and Right. He co-designed and served as the head facilitator for the US Bipartisan Congressional Retreats in the late 1990s, and has spent the following years participating in a wide variety of efforts to deepen dialogue across the political spectrum. This work led to his most recent book The Reunited States of America, which inspired the film The Reunited States, now playing on Amazon Prime.
Mark lives with his wife Melissa in Boulder, Colorado, and has three sons and eight grandchildren.

Mesa Sebree is a researcher, community-builder, and nonviolence practitioner based in Boulder, Colorado. She graduated from Indiana University in 2021 with degrees in Political Science and International Studies specializing in Human Rights and International Law. Her research focused on multi-tiered approaches to peacebuilding wherein international and state agencies work alongside community leaders to create locally-driven restorative practices to promote reconciliation and healing after instances of mass civil division.
Following this, Mesa obtained her M.Sc. from Ghent University in Belgium where she studied Conflict and Global Development, focusing on decolonization and degrowth. Her dissertation analyzed social organizing strategies for transforming popular conflict and achieving democratic reforms, specifically focusing on coalition-building, nonviolent civil resistance, and deliberative dialogue.
Mesa’s impulse to “think global and act local” has led her to work with multiple national support networks committed to uplifting community-based collective action. Her research on the polycrisis/metacrisis heavily informs her theory of change, which is that only by collaborating across sectors and perceived lines of differences can we hope to co-create a people-powered, resilient democratic republic. Personal mindfulness practice and deep connection to community are cornerstones that provide important grounding for her peace work.
In addition to her role with Mediators Foundation, Mesa is the Program Coordinator at Better Together America, a national support network for place-based Civic Hubs.

With their grown children, Elizabeth King, Michael Steiner, and Mara Tasker, John and Margo support the power of film to change our culture and to raise environmental consciousness, largely through Impact Partners, and such films as Chasing Ice, Chasing Coral, The Human Element, The Biggest Little Farm and The Social Dilemma. They are all trustees of the Steiner King Foundation.
John and Margo’s work and life are animated by a long-term commitment to the timeless, non-dual wisdom traditions, the demystification of enlightenment in everyday life, and to planetary awakening.
