BRAINTREE, Mass.— The Affordable Housing and Services Collaborative, Inc. (AHSC) is celebrating its 25th anniversary, highlighting a legacy of partnership-driven development that has delivered thousands of affordable housing units across Massachusetts.
Founded with a mission to provide and preserve housing for low-income families, seniors, individuals with disabilities, and other vulnerable populations, AHSC has grown into a key player in the state’s affordable housing landscape. The nonprofit collaborates with public agencies, private developers, and financing partners to secure funding and resources for housing development, rehabilitation, and preservation efforts.
Over the past quarter century, AHSC has completed more than 47 real estate projects, resulting in the creation or preservation of over 3,300 affordable housing units. These developments span a range of approaches, from new construction to adaptive reuse and historic preservation.
Among its most notable projects are Walnut Knoll Phases 1 and 2, a 200-unit senior housing development built on public housing authority land, and Columbia Uphams, which involved the rehabilitation and preservation of 91 units across two historically significant properties. Other major initiatives include the redevelopment of Powdermill Village, a 248-unit family housing community in western Massachusetts, and the transformation of the Walker School into 40 deeply affordable units for seniors.
AHSC has also embraced adaptive reuse strategies, converting older structures into modern housing. Projects like 98 Essex, a former mill building turned into 62 family housing units, reflect the organization’s commitment to both preservation and innovation.
“Reaching our 25th anniversary is a testament to the continued support of our Board of Directors and dedicated staff, as well as the strong partnerships we have established to deliver on our mission,” said Michael J. Mattos, AHSC’s president and executive director. “Reflecting on our accomplishments over the past 25 years is an inspiration to see how much more we can achieve in the future.”
As housing affordability remains a pressing issue across Massachusetts, AHSC leaders say the organization is focused on expanding its impact in the decades ahead, continuing to leverage partnerships and creative development strategies to meet growing demand.
