Key takeaways

  • The filing describes a broad mix of recipients, including health providers, universities, churches, food pantries, schools and arts organisations, and it states no geographic focus, though most grants have gone to organisations in Nevada, Wisconsin, Florida, Colorado, Mississippi and the United States.
  • Most of its grants are modest: about 8 in 10 of its 78 grants fall between $5,000 and $30,000, and half are $20,000 or less, so a request in that range is typical, although its largest grant was $365,000 and that band is not a ceiling.
  • The filing suggests that existing relationships count for a great deal, since 73% of its grant dollars to organisations went to organisations it had also funded in earlier filings, so a charity that has already been funded may be well placed to return.
  • The filing asks applicants only for a brief description of charitable purpose and gives no deadlines, so you can send a short description whenever it suits your work.

Overview

Thomas A Plein Foundation is a US private foundation based in Appleton, WI.

What they fund

Profile based on the foundation's IRS Form 990-PF filings (TY2025, TY2024, TY2023) only: no website or other web source for the foundation was found. Every statement is checked against the filings. Sources read on 7 October 2026.

Priority Areas

Across the filings, grants were reported as public general contributions. Recipients included health foundations and healthcare providers, universities and colleges, churches and religious missions, youth and community groups, social-service organisations, animal-welfare charities, food pantries, schools and arts organisations. The recipients also included charitable groups serving LGBTQ communities and faith communities. Taken together, the filed grants show support reaching a broad mix of charitable organisations, rather than one dominant recipient type or a named grant field. The filing lists no more specific purposes than public general contributions.

Geographic Focus

No geographic focus is stated; the filings show grants mainly in Nevada, Wisconsin, Florida, Colorado, Mississippi and the United States.
