Ideal Applicant
Small to mid-size charities whose work aligns with public health education, advocacy, legal support, or locally focused community services, especially organizations with existing connections or referral routes into the foundation's network.
Good Fit
- • Mission closely tied to public health education, advocacy, or legal support.
- • Previous relationship, referral, or prior grant history with the foundation or its network.
- • Projects needing small to moderate operational support rather than large multi-year core funding.
- • Located in or active in states where the foundation already concentrates support, particularly Connecticut.
Geography
Observed grants in the latest year reached recipients in 17 states, indicating a multi-state footprint even though a sizable share was concentrated in Connecticut.
Recipient Variety
The latest filing shows 53 distinct recipients in 2023 (and 76 in 2022), demonstrating a broad set of independent grantees despite some dollar concentration among the top recipients.
New Applicants
The foundation's public materials and filing info state grants are by preselection/invitation, and 87% of 2023 recipients were returning grantees with only seven new recipients that year, so unfamiliar applicants are unlikely to gain entry without a referral or invitation.
