Ideal Applicant
A Wisconsin-based nonprofit (particularly in the Fox Valley/Oshkosh–Green Bay area) working on basic needs, mental health, shelter/housing, literacy or organizational capacity and with a demonstrated local track record.
Good Fit
- • Programs focused on food security, housing, mental health, literacy or capacity-building in the Fox Valley area.
- • Established local presence or measurable impact within Oshkosh–Green Bay communities.
- • History of collaboration with local community foundations or other regional service providers.
- • Ability to be introduced or nominated (willingness to engage with foundation staff before applying).
Geography
Giving is heavily concentrated in Wisconsin—about 97% of dollars in the latest year—with the foundation focused on the Fox Valley region rather than a broad multi-state footprint.
Recipient Variety
The latest year shows a large and diverse recipient set (143 distinct grantees), a mix of small and mid-size awards, and both new and repeat grantees, indicating broad institutional variety.
New Applicants
Direct evidence shows roughly 36% of 2023 grantees were new, so unfamiliar organizations do gain entry; however the foundation states awards are by preselection and asks new organizations to contact staff before applying.
