San Jose anchors Silicon Valley in Santa Clara County, stretching from the Diablo Range foothills to the southern edge of San Francisco Bay. The city's service area extends from Milpitas and Berryessa in the north through downtown and Willow Glen to Almaden Valley in the south, with neighborhoods like Evergreen, Cambrian Park, and Rose Garden defining distinct pockets of the metro. The local economy centers on technology companies, advanced manufacturing, and the professional services that support them, while San Jose State University and a network of healthcare systems provide major employment anchors beyond the tech sector.
