Ideal Applicant

A small-to-midsize 501(c)(3) focused on equine rescue, equine therapy, or veterinary education—preferably located in Illinois or a nearby state—seeking single-year grants in the low- to mid-thousands and able to supply prior-year 990s.

Good Fit

  • Mission tied to horse rescue, equine therapy, or veterinary education.
  • Located in Illinois or one of the other states previously funded (CO, IN, CT).
  • Can provide prior-year 990s and basic organizational financials.
  • Request size in the typical $2K–$12K range.
  • Track record of direct service or program work consistent with past grantees.

Geography

Moderate

Grants in the latest year went to organizations in four states, but roughly half of dollars remained in Illinois, indicating multi-state reach with a regional/Illinois concentration.

Recipient Variety

Moderate

The latest year shows eight distinct recipients with several recurring grantees across three years and multiple new entrants, which indicates a moderate diversity of independent recipients for a small private foundation.

New Applicants

Broad

Direct evidence of new entrants exists (five new recipients in the latest year), and the filings include explicit application instructions, a named contact, and a deadline, so unfamiliar applicants have a plausible path to be considered.
