Sontag Foundation
Between its 2021–2024 filings, Sontag Foundation made 25 grants to Florida organizations totaling $8,520,000 — median $10,000. Here is what they actually funded, from their IRS 990-PF filings. A note on dates: 990-PF filings become public one to two years after the fiscal year they cover, so 2024 is the newest year on public record — giving patterns persist, but always confirm current priorities with the funder.
