Ideal Applicant
A small- to mid-sized Massachusetts nonprofit (especially Boston-area) seeking general operating support or program funding in education, internships, food/human services, or community programs and able to engage via an established local contact.
Good Fit
- • Organization based in Massachusetts (Boston/Dorchester area preferred).
- • Programs aligned with education/internship initiatives or community human services.
- • Requests in the foundation's typical grant range (~$2k–$20k).
- • Existing local relationships or introductions to the foundation trustees or named contacts.
- • Comfortable with general operating support rather than restricted, large-scale capital grants.
Geography
Giving is heavily concentrated in Massachusetts, with about 84% of dollars going to in-state recipients despite a small number of out-of-state grants.
Recipient Variety
Nine distinct independent recipients are funded each year, which shows a modestly diverse portfolio for a small foundation, though dollars are concentrated among the top five recipients.
New Applicants
Across three observed years no new recipients were added and the same nine organizations were funded repeatedly, which suggests the portfolio is invitation- or relationship-driven despite a listed contact route.
