About Us

What We Do

Mainstay provides human service and housing programs across Massachusetts, including permanent supportive housing and compassionate, person-centered home care. Our programs have helped hundreds of people live productive and stable lives in their own communities every day for all of these years.

Our History

Mainstay was founded in 1975 under the name Mental Health Programs, Inc. (later MHPI, Inc.)- to provide affordable, community-based housing to people with mental illness. In 1999, a service affiliate, Residential Support Services Inc. (RSSI), was founded to provide care and services to our residents and others in the community. Our mandate has since expanded to cover a variety of vulnerable populations, including low-income elders; people with intellectual, developmental, and physical disabilities; and the recently homeless. In 2019, the companies were merged under the name Mainstay to reflect our integrated programs and approach to care.
