Ideal Applicant
A local Tulsa/OK nonprofit with clear community-facing programs (homelessness, mental health, youth services, or sponsorship-based events) seeking sponsorship-level support or small grants.
Good Fit
- • Operates in Tulsa or elsewhere in Oklahoma
- • Seeks one-time or event/sponsorship-style grants in the ~$2k–$15k range
- • Has an established local presence or existing relationships with trustees or current grantees
- • Provides clear, tangible local impact that aligns with homelessness, mental health, youth, or community services
Geography
The latest year shows every grant went to Oklahoma organizations, and prior years were overwhelmingly in-state with most grants concentrated in the Tulsa area.
Recipient Variety
The foundation funded 11 distinct recipients in the latest year (and 11–15 annually over three years), showing a moderately broad local recipient set despite financial concentration among top recipients.
New Applicants
Direct application is restricted—grants are described as by preselection only and there is no website—but the foundation did add three new grantees in 2024, so occasional new entrants are possible even though unsolicited online applications are unlikely to be a reliable route.
