Ideal Applicant
Organizations with clear alignment to healthcare or faith-based community services, especially those serving lower Fairfield County, CT, or organizations with capacity to accept large institutional grants.
Good Fit
- • Project or institution located in Connecticut or directly serving lower Fairfield County.
- • Healthcare, hospital, medical research, or large clinical services with demonstrable impact.
- • Religious/parish programs and faith-based service providers in the diocese or nearby communities.
- • Ability to submit a letter, proof of 501(c)(3) status and a copy of the most recent Form 990 as requested.
- • Organizational materials that show mission alignment with pastoral care, youth formation, or clinical services.
Geography
Grants went to recipients in five states, but about 91% of dollars stayed in Connecticut and the foundation is CT‑based, indicating a primarily in‑state focus with some out‑of‑state giving.
Recipient Variety
The latest year shows nine distinct recipients across hospitals, national research charities, and multiple local churches and schools, so the recipient mix is varied even though one very large hospital award dominated the dollar total.
New Applicants
Direct multi‑year turnover data are unavailable, but the foundation provides application instructions and a mailed submission route; observed giving is relationship‑weighted (one very large award) so new applicants are plausible but likely need strong local alignment or a clear program fit.
