San Gabriel High School (SGHS) is a public high school located in Los Angeles County, California and operated by the Alhambra Unified School District. It is almost entirely in the city limits of Alhambra with a small portion in the city limits of San Gabriel. It traditionally served students residing in San Gabriel although the balance was shifted in 1994 when San Gabriel Unified School District separated itself from Alhambra Unified. Upon separation, SGUSD opened Gabrielino High School to serve its students. San Gabriel High School now serves students from portions of Alhambra, San Gabriel, and Rosemead. Source: Wikipedia (en)
