Cecili Thompson WilliamsExecutive Director

Cecili Thompson Williams - Executive Director

Cecili is the Executive 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.

Favorite quote: “Do not be daunted by the enormity of the world’s grief…You are not obligated to complete the work, but neither are you free to abandon it.” – The Talmud

Favorite food: Tacos.

Favorite marine animal: Dolphins – they are fiercely loyal, help others both within and beyond their species, are intelligent and strategic, have top-notch communication skills, and do it all with style and flair.

Hometown: This is the hardest question. I’m a 3rd Culture Kid and grew up all over the place so: Orlando, DC, Mexico City, Tel Aviv, and Lisbon.

Yasmeen SilvaPartnerships Manager

Yasmeen Silva - Partnerships Manager

Yasmeen is excited to expose the intersections of the nuclear system with other oppressive systems here in the United States. She is passionate specifically about ending toxic masculinity that fuels violence. Prior to organizing at Beyond the Bomb, Yasmeen organized across the country on issues ranging from a $15 minimum wage to reproductive rights. As Partnerships Manager she can’t wait to bring issue connections to light to build strong, intersectional coalitions that fight for justice and a world without nuclear weapons.

In her free time she enjoys curling up with a good dystopian novel, or staring at art until she feels moved.

Tristan GuyetteField Organizer

Tristan Guyette - Field Organizer

Tristan works as Beyond the Bomb’s Field Organizer and has a passion for exciting and equipping activists. She attended college in Ohio and is based out of Toledo. 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.

Favorite Marine Animal: Manatees! Growing up in Florida they were everywhere, and they’re like big puppies!

Colleen has Bachelor of Arts degrees in Political Science and International Relations from Hobart and William Smith Colleges and a Master of Arts degree in International Relations from American University.
