Harbor City Services (HCS), founded in 1987 in Baltimore, is a nonprofit business affiliated with but not dependent on a community mental health agency, Harbor City Unlimited (University of Maryland Medical System). Although it began as a vocational service of a psychiatric rehabilitation program, HCS is now a self-sustaining social enterprise with two main goals: to generate earned income by providing services to customers and to accomplish a social aim or mission. HCS is successful at both; it has generated over $600,000 per year while meeting its mission to "create vocational opportunities, treatments, and supports for individuals with mental illness and substance use." A workforce of 12 permanent and 35 temporary employees provide four key business services: document management, data destruction, general warehouse services, and commercial moving. This medium-sized enterprise now has 192 regular customers, including prominent medical centers, law firms, and social service agencies.
