To deliver the best patient care and advance health through research, education, and community health programs.
Mass General Brigham Incorporated & Affiliates Group Return’s giving is built around support for tax-exempt affiliate organizations, and the largest recent grants show how central that structure is to its philanthropy. In 2023, it awarded $361,519,368 to The General Hospital Corporation and $272,961,204 to Mass General Brigham Incorporated, both in Boston, each described as support for a tax-exempt affiliate. The same pattern continues across major affiliates including The Brigham and Women's Hospital Inc, Newton-wellesley Hospital, and North Shore Medical Center Inc. That scale makes the foundation unusual among local funders: it is moving very large amounts through a network of affiliated health-care institutions rather than through a broad external grant portfolio. The portfolio also includes medical-group entities and hospitals in Boston, Salem, Newton, Belmont, Northampton, and other Massachusetts locations, showing a systemwide approach to sustaining operations and community benefit. Across the recent grants listed here, the recurring thread is institutional support for connected health organizations rather than project-by-project awards.
Health care delivery is a central theme in the recent grants. The foundation gave $243,396,284 to Newton-wellesley Hospital in 2023 to support a tax-exempt affiliate, and it also backed North Shore Medical Center Inc with $189,366,021 in 2023 for the same purpose. Medical research and education appear in the broader mission statement, while the grant list shows sustained support for clinical institutions and medical groups. For example, Mass General Brigham Medical Group Inc received $141,977,982 in 2023 and $50,792,227 in 2024. Community health shows up through affiliates serving local populations, including Cooley Dickinson Health Care Corporation and Cooley Dickinson Hospital Inc in Northampton. Health equity is part of the stated focus areas, and the funding pattern suggests a system-level strategy centered on affiliates that provide care, training, and community services.
Typical grant size is $15,262 at the 25th percentile, $51,282 at the median, and $182,680 at the 75th percentile, but the recent grants list also includes very large affiliate-support transfers in the hundreds of millions. The funder is a regular grantmaker, not a DAF, and it does not fund individuals or program-related investments. The same recipients appear across multiple years, including Mass General Brigham Incorporated, The General Hospital Corporation, and The Massachusetts General Hospital, which points to recurring institutional support rather than one-time awards. The grant language is highly consistent: support for tax-exempt affiliate, often tied to operating continuity and affiliated health-system needs.
