Partners In Social Change

Third Sector New England, Inc. (TSNE) is a capacity building organization that partners with nonprofit organizations to provide the services, programs, and resources they need to support their communities and ultimately, create a more equitable society. We work with organizations to mitigate barriers, like access to resources and capacity, by ensuring they have the financial, staff, and additional support they need to operationalize their work. In doing so, we partner with organizations to increase sustainability, help do their work more effectively, and lead change.

Our History

We have been working across the nonprofit sector for the last six decades. Throughout these 60+ years we’ve committed to being a trusted partner dedicated to helping people, communities, and organizations thrive.

Founded in 1959

We started as the Massachusetts Health Research Institute (MHRI), founded by leaders from government and academia. MHRI began as a fiscal sponsor for public and community health research and demonstration projects in Massachusetts. Through this work, we recognized the need that many organizations had to create a solid financial and administrative foundation so they could focus on achieving their mission.

Expanding Our Mission

With a shift to Third Sector New England in the late 1990s and later to TSNE, we reinvented ourselves by expanding our mission beyond public health projects to serving communities by supporting nonprofit organizations.

Our Mission

TSNE strengthens organizations working towards a just and equitable society

Our Values

Justice

A just society is one in which all people have the dignity, resources, power, and self-determination to fully thrive. We seek to create a more just world in all of our work.
