Welcome to the beautiful 18^th Congressional District of California. Located between the cities of San Francisco, Santa Cruz and San Jose, the 18^th District includes portions of San Mateo, Santa Clara and Santa Cruz counties. A list of cities and communities located in our District is below.

The 18^th Congressional District is home to several major government agencies, including the NASA Ames Research Center, the 129th Rescue Wing of the California National Guard, the VA Palo Alto Health Care System, the U.S. Geological Survey’s Western Regional Office, and the SLAC National Accelerator Laboratory, operated by Stanford University for the Department of Energy.

The 18^th District is the birthplace of Silicon Valley, world center of the information technology and biotechnology industries. It was here in 1939 in a Palo Alto garage that William Hewlett and David Packard started their firm and today, sixty-one years later, Larry Page and Sergey Brin met here at Stanford University and went on to found Google nearby. The electronics and technology industries continue to flourish, and leaders such as LinkedIn, Netflix, HP, Google, Symantec, Intuit, VMWare and a host of other leading firms are headquartered in the 18^th District.
