This case study is based on a 1988 site visit to the Orion Community, in which a group of nondisabled and disabled people have chosen to live and work with each other in Chester County, Pennsylvania. Orion's founding is described, beginning with an informal support group of professionals, parents, advocates, and members of Camphill (agricultural villages that welcome individuals with developmental disabilities). The founding group sought to support people coming out of Pennhurst, a large state-operated institution for individuals with mental retardation and other disabilities; to build upon the presence of Camphill; to acknowledge the important contributions that people with developmental disabilities can make to the community; and to include a spiritual and religious foundation. The case study describes the households where the members live with each other, the Guild House where some Orion members and others work together, the encouragement of lifesharing, the offering of hospitality, decision making in the community, care groups, and compliance with state regulations.
