Community Service Organization
The Community Service Organization (founded 1947) was an important California Latino civil rights organization, most famous for training Cesar Chavez and Dolores Huerta. It was founded in 1947 by Fred Ross, Antonio Rios and Edward Roybal and was a source of political support for Roybal during his long political career. Ross had been hired by Saul Alinsky and was employed by his Industrial Areas Foundation.
