Ideal Applicant
Small or mid-sized community nonprofit or individual scholarship applicant with programs anchored in Wisconsin or other states where the foundation has given, especially organizations serving youth, health, community services, and local emergency or education needs.
Good Fit
- • Organization based in Wisconsin or in one of the other states where grants were observed.
- • Program areas in youth mentoring, health, community services, education, emergency services, or workforce/trades training.
- • Ability to submit a concise request by the website form, email, or mailed packet and to demonstrate local ties or community impact.
- • As an individual: eligibility for the foundation's scholarship rules (geographic connection, under age 24, attending postsecondary training).
Geography
Grants in the latest year went to organizations in 12 different states, showing a multi-state footprint, although about two-thirds of dollars remained in Wisconsin.
Recipient Variety
The latest year shows 106 distinct recipients funded, with small-to-midsize awards distributed across many independent charities rather than concentrated in a single beneficiary.
New Applicants
Direct evidence from 2024 shows all 106 recipients were new that year and the foundation provides public application instructions and contact routes, so unfamiliar applicants appear plausibly able to enter the portfolio; longer-term turnover beyond the recent giving burst is limited in the filings.
