Thalia Zepatos

Thalia Zepatos has over 30 years’ experience in campaign strategy and messaging.

She worked for over a decade in the US movement to win marriage, and served as Freedom to Marry’s Director of Research and Messaging for five years. She is widely recognized as the “message guru” who led the marriage movement’s collaborative shift in messaging, resulting in exponential growth in public support for marriage that paved the way to four successful referenda battles and eventually a Supreme Court victory.

Zepatos has a long track record in developing legislative and referendum strategy and messaging for multiple social movements in the United States. She served as an adviser to the Yes Equality! Campaign in Ireland in 2015 and the nationwide Australian Postal Advisory Referendum in 2017.  Since then, she has continued to consult internationally on campaigns to win marriage and decriminalize homosexuality in Asia, Eastern Europe, and Latin America.

Zepatos is the co-author of Women for a Change: A Grassroots Guide to Activism and Politics and is the author of two other books.
