The Arc of San Diego, a private, not-for-profit corporation, is one of the region's largest human service agencies. We provide an extensive array of services to people with disabilities in San Diego County. Founded in 1951, by a determined group of parents and other community members who were concerned about the lack of services available for children with disabilities, The Arc of San Diego blends a long history of service with a national reputation for success. Today, we are guided by the same sense of purpose and dedication that inspired those parents over 70 years ago.
