Overview
Three Sibs Foundation Inc was established in 2021 as a private grantmaking foundation based in Atlanta, Georgia. The foundation holds approximately $13.7 million in assets as of 2024 and made charitable disbursements of approximately $178,000 in 2024. The foundation made 14 grants in 2023, 13 grants in 2022, and 10 grants in 2021, showing consistent grantmaking activity since its inception.

The name "Three Sibs" likely refers to the three Kennedy siblings involved in the foundation's governance.
