Jul / 13 / 2018


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.

The management and consulting services, training programs, and community-based grants and investments we offer are designed to meet the needs of complex and growing organizations by strengthening communication and leadership skills, facilitating learning and strategic thinking, and providing practical and operational support to individuals — all toward the goal of increasing their mission impact. Our ongoing partnerships with foundations, service providers, community groups, nonprofits and thought leaders provide us with opportunities for 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, expand our programs and resources, evolve to meet the needs of a rapidly changing nonprofit landscape, and 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. In doing so, we have a longstanding commitment to racial equity and social justice. Our community funding program, The Inclusion Initiative, is well-regarded. There is an opportunity to better integrate current field learning regarding racial equity work into our programs. Internally, there is ongoing work on interracial and intercultural trust and understanding. Enhancing cultural competency, communication and the capacity to work effectively with diverse community-based organizations is our priority.
