Richard Barrera

Board Member Emeritus

President, San Diego Unified School District

As a community organizer with the Local Initiatives Support Corporation and the Consensus Organizing Institute, Richard worked with residents of neighborhoods from San Diego to Chicago to Little Rock and Las Vegas to build affordable housing, improve schools and public transportation, establish job training programs and increase voter participation.

As a union organizer with the United Domestic Workers of America, SEIU United Healthcare Workers, and the California Nurses Association, Richard helped home care providers and service workers in hospitals win new organizing drives; negotiate higher standards in wages, benefits and patient care protections; and build political power.

In 2008, Richard was elected to the San Diego Unified School Board, representing the communities surrounding San Diego and Hoover High Schools. During a period in which public schools in San Diego faced historic budget cuts from the State of California, Richard helped build coalitions of parents, students, teachers, classified workers, administrators and community leaders to protect the outstanding work going on in neighborhood schools. This process of community-based reform – distinct from top-down corporate reform – has produced unprecedented gains in student achievement, narrowing of the achievement gap, and reduced dropout rates in San Diego’s public schools.

San Diego Unified is now recognized as one of the top performing large, urban districts in the nation, and has received prestigious awards for its groundbreaking work in science instruction, arts and music education, career technical education, and classroom technology.
