Ideal Applicant
An established Pennsylvania-based nonprofit (often in the Pittsburgh area) seeking general operating support in health, human services, faith-based, education, community services, or animal welfare with an existing local track record and relationships.
Good Fit
- • Organization serves the Pittsburgh/greater Pennsylvania community.
- • Request is for general operating support rather than a narrowly defined project.
- • Has an existing relationship or can secure an introduction from a trustee, sponsor, or past grantee.
- • Organization is established with multi-year operations and demonstrable impact.
Geography
Giving is heavily local: roughly 92% of dollars and about 97% of grant counts went to Pennsylvania recipients in the latest year, with only one other state receiving a small share.
Recipient Variety
In each observed year the foundation funded about 32 distinct recipients across hospitals, human services, faith-based groups, education, community organizations and animal welfare, indicating a broad and diverse recipient set for a small private foundation.
New Applicants
The foundation explicitly indicates it only funds preselected grantees and there is no public application path; although five new recipients appeared in 2024, the portfolio is dominated by repeat grantees (27 repeats), so unsolicited applicants are unlikely to gain entry without a relationship or invitation.
