About Susan Thompson Buffett Foundation
The Susan Thompson Buffett Foundation concentrates on reproductive health, abortion access, and health systems strengthening—especially across sub‑Saharan Africa—while also backing U.S. abortion access infrastructure and research/training. It funds a mix of government health ministries, global institutions, technical training centers, and U.S. reproductive‑rights nonprofits and intermediaries, often providing large multi‑million dollar grants and repeat support to core partners. The foundation’s giving emphasizes capacity building (training, health bureaus, ministries), direct service and crisis support (abortion funds, hotlines), and policy/advocacy infrastructure via funder intermediaries.

About Susan Thompson Buffett Foundation
The Susan Thompson Buffett Foundation’s largest recent grants show a clear pattern of very large checks to abortion access and public-health systems. In 2025 it gave $60,574,746 to NAF Hotline Fund for program support, following $54,890,802 in 2024 and $48,427,544 in 2023 to the same recipient. The foundation also made major health-system grants across sub-Saharan Africa, including $50,000,000 to the Federal Ministry of Health and Social Welfare Nigeria and $36,742,555 to Imbuto Foundation in Rwanda. Its work is not limited to one channel. The foundation funds national ministries of health, regional health bureaus, reproductive-health training groups, hospitals, global health institutions, and U.S. abortion-access organizations. Recent awards include support for the World Health Organization, Planned Parenthood Federation of America Inc, and the Center for International Reproductive Health Training. The pattern suggests a grantmaker that uses large, repeated awards to sustain core partners over time, rather than distributing many small grants across unrelated causes. The foundation also funds individuals through a scholarship program for Nebraska students.
