Ideal Applicant
Small-to-mid sized nonprofits in arts/culture, conservation, education, or local historical institutions with regional ties (especially to Kansas and nearby states) seeking operational support at typical grant sizes from roughly $5k–$50k.
Good Fit
- • A mission in arts, museums, conservation, or local education
- • Demonstrable regional connection to Kansas, Oklahoma, or the other states in the grant footprint
- • Request size aligned with past grants (approx. $10k median, occasional $25k–$50k awards)
- • Capacity to use general operating support rather than complex restricted project funding
Geography
Grants span five states rather than a single city or county, but giving is regionally concentrated with roughly 43% of dollars going to one state.
Recipient Variety
The latest year funded 23 distinct recipients (24 grants) and the three-year history shows dozens of independent grantees across arts, conservation, and education, indicating a broad recipient set despite some repeat grantees.
New Applicants
The foundation explicitly accepts applications at any time by mail/phone and the latest year included four new recipients alongside 19 returning ones, so unfamiliar organizations have an observable path to enter the portfolio.
