The Epilepsy Foundation is the national voluntary agency solely dedicated to the welfare of the 2.7 million people with epilepsy in the U.S. and their families. The organization works to ensure that people with seizures are able to participate in all life experiences; and to prevent, control and cure epilepsy through research, education, advocacy and services. In addition to programs conducted at the national level, epilepsy clients throughout the United States are served by affiliated Epilepsy Foundation offices in nearly 100 communities. The three affiliates in California are the Epilepsy Foundation – Greater Los Angeles, Epilepsy Foundation of Northern California, and Epilepsy Foundation of San Diego.
