This funder does not accept unsolicited applications. The foundation chooses the organisations it funds itself.

Key takeaways

  • The foundation makes contributions only to organisations it has preselected and does not accept unsolicited requests, and the filing gives no public application steps, so an unsolicited request should not be sent and the realistic route is an existing connection.
  • Its recorded grants cover youth-serving, community, housing and education organisations and some facility projects, so a small charity working in one of those areas may fit, though no geographic focus is stated.
  • Most of its grants fall between $50,000 and $500,000, with a median of $150,000; that band is typical rather than a ceiling, since its largest grant was $600,000, so a request in the low hundreds of thousands is plausible once a relationship is in place.
  • Repeat giving is strong: 86% of its grant dollars in the latest filing went to organisations it had funded in earlier filings, so a new organisation should expect to compete with established grantees for a place.

Overview

Tomlinson Foundation is a US private foundation based in La Jolla, CA.

What they fund

Profile based on the foundation's IRS Form 990-PF filings (TY2024, TY2023, TY2022) 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

The foundation’s recorded grants have gone to a mix of youth organisations and community providers, including boys’ and girls’ clubs, a foster-youth organisation and YMCAs, alongside a housing sanctuary, a charter-school network and a church. Most grants were recorded as general support. Other recorded purposes included construction of a vocational centre and an aquatics centre. Its grants thus cover recurring support for youth-serving, community, housing and education-related organisations, as well as some facility projects. The record describes a varied set of recipients and purposes rather than a single type of organisation or project.

Geographic Focus

No geographic focus is stated; the filings show grants mainly in California and Idaho.
