Clinica Sierra Vista, a non-profit corporation begun in December 1971, was created to provide health care to poor, migrant farmworkers who harvest the lush agricultural fields in the southern San Joaquin Valley. Today, Clinica Sierra Vista serves a geographically dispersed, low-moderate-fixed income, ethnically diverse, frontier-rural-urban-migrant-homeless patient population. It has grown to be one of the largest comprehensive migrant/community health center systems in the state.
