The Massachusetts Housing & Shelter Alliance (MHSA) is a statewide organization that is driving innovation in the effort to end homelessness among adult individuals through advocacy and development of new outcome-based programs. For 25+ years, MHSA has been transforming the traditional response of emergency shelter into a system of permanent housing, improved access to services and health care, and other long-term solutions to homelessness. These strategies have helped to dramatically reduce chronic homelessness in Massachusetts and gained MHSA national recognition for several policy initiatives. MHSA has a network of nearly 100 member agencies; it also works closely with state and city government. It uses its unique position as an intermediary between public agencies and homeless service providers to create innovative responses to homelessness for adults in Massachusetts.
