San Ramon

San Ramon (Spanish: San Ramón, meaning “Saint Raymond”) is a city in Contra Costa County, California, United States, located within the San Ramon Valley, and 34 miles east of San Francisco. San Ramon is home to the headquarters of Chevron Corporation, Cooper Companies, the West Coast headquarters of AT&T, GE Digital, as well as the San Ramon Medical Center. Major annual events include the Art and Wind Festival on Memorial Day weekend and the Run for Education in October.

Bishop Ranch, a master-planned office park development, with some retail elements, began major construction in the early 1980s, and provides a healthy tax base for the city. Bishop Ranch is situated on 585 acres once owned by Western Electric, and was farmland before that. Current tenants include the corporate headquarters of Chevron Corporation (formerly ChevronTexaco), as well the West Coast headquarters of AT&T Inc. (which had been the headquarters of Pacific Bell from about 1983, when it relocated from downtown San Francisco, until the merger with SBC Communications that created the current AT&T).
