Not every foundation here is a San Antonio foundation. The city is the mailing address on the foundation’s tax filing, and when a bank or a law firm runs the trust that is the bank’s address, not the place it gives to. Check where a foundation gives before you write.

  • Median grant and grant range come from the 990-PF grant schedule; a dash means there is none to report.
  • “One grant” means a schedule with a single grant — no median, nothing to range over. “One amount” means several grants, all the same size.
  • 3-yr trend compares the latest filing year with the year two before it, so it needs grants on file for both. Most foundations file one year of grants, so most rows show a dash.
