About Us

We believe strengthening the people and organizations that support and improve our communities is a potent catalyst for social change.

For more than 60 years, TSNE MissionWorks (formerly Third Sector New England) has been a trusted partner to hundreds of nonprofits, foundations, community groups, activists, and advocates who are making a difference in their communities, our country, and the world.

Our management and consulting services, training programs, and community-based engagement activities are designed to meet the needs of complex and growing organizations, strengthen leadership skills, facilitate learning and strategic thinking, and provide practical and operational support to individuals—all toward the goal of increasing their capacity to achieve their mission.

The ongoing partnerships we have with foundations, service providers, community groups, nonprofits and thought leaders in the sector provide us with opportunities for constant reflection and learning – which strengthens our own programs and services and provides an opportunity to explore trends in the nonprofit sector.

We continue to deepen our partnerships, to expand our programs and resources, to adapt and evolve to pursue excellence in the services we offer to hundreds of mission-driven organizations every year—so together we can create a more just and democratic society.

On our new name and tagline

In June 2017, Third Sector New England became TSNE MissionWorks: a name that speaks to our ongoing investment in the missions of our clients and partners, and our collaborations far beyond the borders of New England. Along with our new name, we gained a new tagline: Partners in Social Change. These words speak to our role as a committed partner to mission-driven organizations—and the role of those partnerships in driving social change.
