The Missoula Developmental Service Corporation (MDSC) was developed in 1990 to provide intensive community-based services for 54 adults with developmental disabilities. The project was the result of a special initiative funded by the State of Montana and grew from community interest.

The services provided by MDSC are based on the needs, desires and abilities of its clients to live, work, play and be healthy. Emphasis is placed on increasing clients' communication, self-help and socialization skills and providing opportunities for decision making. It is the purpose of the corporation to promote independence and community involvement to enhance the quality of life for people served.

The Corporation includes seven group residences located in typical neighborhoods and offering a variety of experiences and options for residential living. Services are provided 24 hours a day, 7 days a week.

In addition to its residential services, MDSC provides day services, with instructional emphasis on vocational skills, and including communication, survival skills and specialized therapies. Day services occur primarily at the MDSC center located at 1005 Marshall Street.
