For more than 50 years, ARC has served individuals with Developmental Disabilities from the greater Los Angeles area.

Most of the clients served have Down syndrome.

We reach more than 4,000 in in the community annually through educational outreach as part of our inspirational Hand Bell and Chime Choirs.

Our History

ARC was created in 1969 through the determination of Mary Schallert and Dixie Henrikson- two mothers who fought for their daughters with Down Syndrome to become active members of the community, grow up with their family and friends, and lead meaningful and quality lives. With the support of other concerned parents, volunteers, and community members, these visionary leaders paved the way for individuals with developmental disabilities to gain access to services that enrich their lives and help them reach their full potential.

In 1975, ARC was incorporated as a charitable, nonprofit tax deductible corporation through the support of family members who volunteered legal and accounting services. Between 1985 and 2004 with the purchase of five adjacent properties in the North Hollywood community, ARC and its impact in the community grew. In 2014, ARC acquired its sixth adjacent property in the North Hollywood area of Los Angeles County.

In addition to providing direct services to individuals and their families, ARC advocates and brings awareness to the community about developmental disabilities. ARC also partners with community based organizations, colleges, high schools, Special Olympics, and other agencies to provide opportunities to over 350 volunteers each year. ARC volunteers bring a rich diversity to our programs and extend our reach in the community for educational and informative outreach opportunities.

Our Mission

We provide the resources, programs, education, and environment to support the independence and inclusion of people with intellectual and developmental disabilities. We partner with them towards fostering social relationships, cultivating their individual talents, allowing them to reach their full potential and a life filled with dignity, compassion, and respect.

Our Vision

ARC envisions a world where people with developmental disabilities live a full life as individuals who are included, accepted, and valued without stigma or limitations.
