Staff & TerraCorps Members

Mount Grace Staff

Emma G. Ellsworth

Executive Director

Emma comes to Mount Grace as an avid hunter, angler, hiker, and outdoors woman. She lives at the base of Mount Tully, a Mount Grace protected property. Emma feels very passionate about protecting her “backyard” and grateful to be able to call it a job. Emma spent the last 20 years as a union organizer and negotiator, fighting for social justice, for working class people to have a voice on the job, and for a chance at a decent quality of life. She is thrilled to be applying those same collaborative skills to conservation, She believes deeply in our need to bridge differences, foster a culture of finding common goals, and stand up for what we believe in if we are to be successful. She follows in the footsteps of her family, who were active Mount Grace Community members. Love of the land is in her blood. In this age of crazy storms, unprecidented weather, and bird population decline, conservation of our “backyard” is more important than ever. 

As a member of the seven person board of MassWildlife and specifically representative of the Agricultural Interest, Emma is able to have a statewide voice, advocating for protection of our state’s biodiversity.

Jenn Albertine

Climate and Land Justice Specialist/Conservation & Stewardship Associate

Jenn is responsible for the integration of Climate and Land Justice into every aspect of Mount Grace’s work: conservation, stewardship, and outreach. Before Mount Grace, she held a faculty position at Mount Holyoke College in the Environmental Studies Department where she taught classes that focused human-environment interactions associated with climate change, environmental pollution, sustainability, and food systems- all from the perspective of human health and social justice. Jenn holds a Ph.D. in Plant and Soil Sciences and a B.S. in Environmental Science, both from the UMass Amherst. She held postdoctoral positions at Harvard Forest and UMass Amherst. Her academic research focused on how climate change will impact plants that produce allergenic pollen both within populations and across the landscape, and thus impact human health. Outside of work, she plays leadership roles in two community organizations working to create racial equity and justice: The Holyoke Food and Equity Collective, focused on creating a more equitable and just food system in Holyoke, MA through direct action and policy work, and the Petersham Anti-Racism Coalition (PARC), focused on education, awareness, and action to help our rural communities find our roles in building racial equity and ending systemic racism. In her free time, you can find her on wheels or sled runners behind her team of Siberian Huskies, where she is the lead musher for the Swift River Siberians racing team, as well as working in her garden in the summer.  E-mail:

Tessa Dowling

Stewardship Manager

Tessa has been catching frogs and poking under logs since she was a kid. Her inquisitive nature led to an invasive species lab at UMass Amherst, a master’s program studying salt marshes in Maine, and back to Massachusetts to serve as a TerraCorps member at Hilltown Land Trust. Serving as their Land Stewardship Coordinator made her realize conservation work connected all the pieces she loved about being an environmentalist: community, sustainability, research and education. When not delving into natural history, she can be found practicing swing dancing or attempting to quilt.  E-mail:
