Our Team

Cecili Thompson Williams - Director

Cecili is the Director of Beyond the Bomb, leading a team of kick-ass campaigners and activists to mobilize against the threat of nuclear war and weapons. She has nearly two decades of experience leading mission-driven campaigns with organizations including Amnesty International USA, RESULTS Educational Fund, and the National Partnership for Women & Families. Most recently she founded and served as the Chief Strategist for We Divine Water, a consulting group helping smart and passionate changemakers build strategic and effective campaigns. A strong believer in continually building power and capacity, Cecili has trained thousands of campaigners on how to maximize their impact within their organizations and in the world at large. She also serves as a faculty member at the Center for Social Design at the Maryland Institute College of Arts where she teaches a graduate seminar on campaign strategy. When she’s not campaigning, she can be found freezing at an ice rink with her skating daughters or running slowly in a forest.

Tristan Guyette - Field Organizer

Tristan is a freelance data nerd who believes science and information can fix pretty much anything. In the past she’s worked to educate voters on Ohio’s changing registration laws and to protect reproductive rights. When she’s not organizing for change she’s surrounded by a pack of shepherds, probably looking for their frisbee.
