Jonathan Spack

Jonathan Spack has over 30 years’ experience leading and consulting to nonprofit organizations. During his 26 years as executive director of Third Sector New England and its predecessor, he has successfully guided the organization through several transitions, including its re-invention as a leading regional capacity-builder and resource center for small to midsized nonprofits. 

Founded in 1959, TSNE is one of the nation’s most experienced fiscal sponsors. In 2004 it acquired a historic 120,000 sq. ft., office building in Boston’s Leather District which it has developed into the NonProfit Center, “Boston’s Home for Progressive Social Change.” The NPC is currently home to 29 nonprofit organizations, including the Center for Legal Aid Education.

Earlier in his career, Jonathan worked with community-based organizations in Massachusetts and New Jersey and with Native American groups in North Dakota and Zuni, New Mexico, as a VISTA Volunteer, "Reggie" (Reginald Heber Smith Community Lawyer Fellow) and Legal Services attorney (his law degree is from New York University). He is co-author of the Executive Director’s Guide, published by TSNE in 2002, and is a founding member of the Nonprofit Centers Network, the National Network of Fiscal Sponsors and the Massachusetts Nonprofit Network.
