The first Latina and first immigrant woman to become president of a national union in the United States, Teresa Romero replaced Arturo S. Rodriguez as the third president of United Farm Workers in December 2018. Formerly the union’s No. 2 officer as secretary-treasurer, she has years of experience overseeing the complex operations of a far-flung organization involved in field organizing, contract bargaining and administration, legislative and legal advocacy, and far-reaching international initiatives.

Before joining the UFW, she managed a construction company and a law firm that helped workers with immigration and workers compensation claims. Teresa Romero is proud of her U.S. citizenship and proud of her Mexican and Zapotecan heritage.

She is widely respected by her peers for her work ethic, calm competence, relationship building, and Si Se Puede! spirit.

Her leadership rose to new levels in the epic farm worker march from Delano to Sacramento in 2022. She took every step alongside farm workers marching 335 miles across rural, dusty Central Valley in the searing August heat to win farm workers the right to a safer union election process.

Her presidency has overseen a new wave of farm worker organizing from New York to California.
