Four decades of dignity, respect and empowerment
A 40-year legacy
of dignity, respect and empowerment
For 40 years, MHSA has strengthened the community through critical shelter, recovery and nutrition supports.
Incredible things are possible when an entire community rallies around a single, powerful mission.
The mission begins
On October 19, 1977, a group of concerned professionals with links to the substance abuse world created the Middlesex Regional Alcoholism Treatment Center (MRATC). With a small office in Watertown, Massachusetts and program facility in Waltham, the MRATC was a stand-alone alcohol detoxification program that provided various services including detoxification, Short Term Intensive Inpatient Treatment (STIIT) and Transitional Care for nearly two decades.
Stationed on the grounds of the former Middlesex County Hospital, the MRATC was strategically positioned to cultivate relationships with an array of local service providers, including at least one that would later be acquired by the company after several years.
The mission of Middlesex Human Service Agency, Inc. is to improve the quality of life and independent functioning of a wide variety of clients through the delivery of an extensive system of community-based substance abuse and social service programs. Although our programs are many and varied, all emphasize dignity, respect and empowerment. We believe in teaching individuals and families the skills and problem solving abilities needed for self-sufficiency.
Rallied around MHSA's mission to help those in need, our team includes more than 200 dedicated and highly-trained clinicians, managers, administrators, direct care workers and professional staff.
Beyond representing nearly a dozen spoken languages, our employees embody a diverse range of cultural, socioeconomic, educational and professional backgrounds.
MHSA team members undergo training on a spectrum of topics, such as cultural competency, nonviolent crisis intervention, trauma-informed care, overdose reversal, LGBTQ issues, motivational interviewing and more.
