Funding pattern
What this funder pays for, at what size, and how to position adjacent work. Read from their filings, with every number checked against the record.
Where the money goes
- Wisconsin higher education: UW Foundation, Fund for Wisconsin Scholars, Alverno College
- Biomedical research at the Morgridge Institute in Madison
- Transfers to a Fidelity Charitable donor-advised fund (Taupo)
- Milwaukee K-12 and youth programs: MPS, Boys and Girls Club, City Year
- Food banks, shelters and safety-net relief in small checks nationally
- Squam Lakes area New Hampshire conservation and community groups
Typical grant
Two entirely separate giving programs sit in one 990. The median grant is $5,000 and the middle half runs $2,500 to $25,000, which describes hundreds of small gifts to food banks, shelters, land trusts and local youth groups. The money, though, is in a handful of eight- and nine-figure checks to Wisconsin institutions and one $29.3 million transfer to a Fidelity donor-advised fund. With 416 grants to 259 recipients across three years, most small grantees are repeats at roughly the same amount each year.
Their words
Phrases from their own grant descriptions, worth speaking back to them.
- “EDUCATION”
- “MEDICAL”
- “INTERNATIONAL”
- “US AID”
- “CONSERVATION”
- “GENERAL PURPOSES”
Positioning adjacent work
- Wisconsin affiliation is the strongest signal; frame work through UW-Madison, Morgridge Institute, or Milwaukee schools.
- Outside Wisconsin, ask $5,000 to $25,000 and expect renewal, not a transformational first gift.
- Bay Area peninsula and Plymouth/Squam Lakes NH addresses draw repeat small grants; lead with local footprint.
- Label the request in their own terms: EDUCATION for student access, MEDICAL for research or clinics.
Worth knowing: This is family giving with clear geographic anchors: Portola Valley and the San Mateo peninsula, Madison and Milwaukee, and the Squam Lakes corner of New Hampshire, with almost everything else in $2,500 checks to national relief brands. Nearly all the dollars go to a few Wisconsin institutions with long family relationships plus a large donor-advised fund transfer, so a cold approach realistically competes for the small-grant tier.
Top recipients
Repeat recipients are the strongest signal of whether a funder has an open door or quietly re-funds the same organizations.
