Our mission is to empower people with intellectual and developmental disabilities and their families to lead better lives by providing a lifetime of high-quality services, family support and advocacy. We work hard to provide the kind of individualized services that can really help make a difference to an adultā¦ to a childā¦ to a family. Services provided are designed to maximize choice and to support people, as they build quality lives within the St. Louis community. The Arc's YouTube channel provides videos about our programs and the people we support, as well as resources for the Arc community.
