Yawkey Foundation

Yawkey Foundation

Thomas A. Yawkey and Jean R. Yawkey created the foundation structure in the late 1970s. Yawkey Foundation I began in 1976 with a conservation mandate in South Carolina. Yawkey Foundation II followed in 1982 with a broader focus on health care, education, and human services in Massachusetts. The foundation holds a 4.89 percent allocation to private equity alongside public equity positions and bond funds. Confirmed holdings include interests in ICM Small Company Portfolio and IR+M Core Bond Fund II reported in the 2023 990-PF filing. Geographic activity centers on Massachusetts and South Carolina with direct ownership of facilities such as the Tom Yawkey Wildlife Center and the Yawkey Center for Cancer Care at Dana-Farber. The foundation maintains relationships with Income Research + Management as investment advisor and Blackbaud for grant management software. It belongs to Philanthropy Massachusetts. No operational events from the last 24 months appear in available records. The foundation's architecture separates grant-making from investment management through two distinct legal entities established decades apart, each tied to specific geographic and programmatic mandates.
