Key takeaways

  • The foundation, based in Dallas, funds education, medicine and the arts, with particular emphasis on medical and scientific research and STEM education, and it does not fund individuals, scholarships, loans or prizes.
  • Its stated priority is Texas and its filing shows a preference for local institutions, so a Texas organisation has a natural case to make, though that is an emphasis rather than a limit on who may apply.
  • Its grants are large: the median is $1,000,000 and the largest is about $38,500,000, so a small organisation should ask for what its project needs rather than aim at these figures.
  • Repeat giving makes up 47% of its grant dollars to organisations, but the filing gives no deadlines and says it accepts applications, so a first approach is open.
  • Send a brief letter covering the project, timetable, budget, funds already pledged and the amount requested, with the governing-board list and IRS determination letter.

Overview

O'Donnell Foundation is a US private foundation based in Dallas, TX.

What they fund

Profile derived from the foundation's IRS Form 990-PF filings (TY2025, TY2024, TY2023) and web pages about the foundation (tamest.org), with every statement checked against those sources. Sources read on 12 October 2026.

Priority Areas

The O’Donnell Foundation focuses on education, medicine and the arts, with particular emphasis on medical and scientific research and STEM education. Its work also encompasses higher education, clinical care and educational initiatives beyond STEM. It supports cultural institutions and Texas institutions, while its stated reach extends beyond Texas. Its grants are directed to organisations: its application information asks applicants to provide their organisation’s governing-board list and tax-exempt-status determination letter, and its filing states a preference for local institutions. The evidence describes institutional giving across education, research, medicine and the arts, rather than scholarships or individual grants.
