The Hunter Grubb Foundation Inc
The Hunter Grubb Foundation Inc was a private foundation based in Old Lyme, Connecticut. Its 2020 filing reports grants to charitable organizations, including groups working on farmland conservation, food access, sustainable agriculture, and environmental protection. The foundation’s 2019 filing was marked as a final return and says it merged into the Martha Grubb Foundation, which changed its name to the Martha and Hunter Grubb Foundation, effective June 30, 2020; all assets were transferred. The foundation therefore appears to have wound down as a separate grantmaker.
