Our Team

TerraCorps Staff


David Graham Wolf, TerraCorps Spin-off Director

David is leading the spin-off of TerraCorps. Since 2007, David has provided leadership for Mount Grace Land Conservation Trust, first as Conservation Director, currently as Deputy Director. He is the visionary leader who designed the MassLIFT AmeriCorps program model and charted its course for growth from a pilot project to its present statewide scale.

David is an unshakable advocate for the authentic engagement of diverse peoples in the mission-driven work of land conservation. As an experienced leader, he understands that people from all walks of life have different personal and cultural connections to the land and it is productive to explore these connections together. Having once measured success solely by counting acres conserved, he now sees victory in each invitation he receives to collaborate with people and organizations who are seemingly disconnected from the traditional land conservation mission.

David is a conservation biologist, entrepreneur, and educator with an M.S. from Antioch University New England, and M.Ed. from UMass-Boston, and B.S. from Johnson and Wales University. Prior to his tenure with Mount Grace, he helped land trusts and municipal commissions prioritize conservation land acquisitions as managing partner of a small consulting practice, and also served at Franklin Pierce University as an adjunct professor of natural sciences.  wolf@mountgrace.org
