Angélica Salas, Executive Director of CHIRLA (Coalition for Humane Immigrant Rights)
Angelica joined CHIRLA in 1995 and became CHIRLA’s Executive Director in 1999. In her role, she has transformed CHIRLA into a mass membership immigrant-led organization that empowers immigrants and their families to win local, state, and national policies that advance their human, civil, and labor rights. She has grown CHIRLA into one of the nation’s largest and most effective immigrant rights organizations that organize, advocates, educates, and provides legal services to all immigrants.
