The Arc in Hawai'i is an organization founded in 1954 by a group of parents of children with intellectual disabilities. Today, The Arc in Hawaii serves almost 200 adults with intellectual and/or developmental disabilities on the island of Oahu, by providing both housing and day programs. As the state chapter of The Arc of the United States, The Arc in Hawai'i is part of the largest national organization devoted solely to working on behalf of people with intellectual disabilities. An estimated 7.2 million Americans have intellectual or a related developmental disability. Through aggressive advocacy at the local and national level, The Arc ensures that these individuals have access to the services and supports they need to grow, develop and participate in communities across the country.
