The Leerink Family Foundation concentrates its giving on youth-focused education and mentoring in the Boston area, with especially strong, repeated support for a private independent school (The Park School) and youth mentoring/after-school organizations. Grants are typically unrestricted/general operating support and appear intended to sustain program capacity rather than seed new initiatives. The foundation favors a small number of sizable gifts to local institutions that serve children and adolescents.
A repeated pattern of general support for Boston-area youth organizations defines Leerink Family Foundation Inc. In the recent grants list, Bbbs of Mass Bay received two separate $50,000 awards in 2025, and Park School Corporation received $50,000 in 2025 after a $50,000 annual-fund grant to The Park School in 2024 and a $35,000 grant to The Park School - Spark the same year. That combination points to a funder that makes sizable, sustained gifts to a small set of local institutions rather than one-off awards across many causes. The foundation’s recent giving also extends to Camp Harbor View, Team IMPACT, Team New England, and other Boston-area nonprofits serving children, adolescents, and students. Several of those grants are labeled general support, and the grant list includes both school-based and out-of-school-time organizations. The foundation’s median grant size is $12,500, but its recent awards cluster higher for a few recurring recipients. With 91% of grants going to recipients in Massachusetts, its work is tightly centered on local institutions in and around Boston.
Youth mentoring appears in multiple grants. Bbbs of Mass Bay received two $50,000 general-support grants in 2025, showing a strong emphasis on mentoring infrastructure for children and adolescents in Boston. School support is another clear thread. Park School Corporation received $50,000 in 2025, while The Park School - Annual Fund received $50,000 in 2024 and The Park School - Spark received $35,000 in 2024. Those grants suggest sustained support for an independent K–12 school and its related programs. The foundation also backs youth development outside the classroom. Camp Harbor View received $25,000 in 2024 and Camp Harbor View Foundation received $10,000 in 2025. Team IMPACT received $25,000 in 2024 and $12,500 in 2025, linking the funder to adaptive sports and youth empowerment through sport.
Grant size is concentrated at the upper end of the foundation’s typical range: p25 is $5,000, median is $12,500, and p75 is $25,000. Recent awards include several $50,000 grants, which sit above that band and indicate room for larger commitments to select recipients. The record also shows repeat support across years, especially for school-related and youth-serving organizations. All listed recent grants are marked general support, suggesting unrestricted or broadly usable funding rather than project-only awards. The foundation is classified as a regular funder, not a DAF or program-related-investment vehicle.

Giving is overwhelmingly local. Massachusetts recipients account for 91% of grants, and the recent list is entirely U.S.-based. Boston appears frequently, including grants to Bbbs of Mass Bay, Camp Harbor View, MA Wonderfund Inc, and Bridge Over Troubled Waters. Brookline and Cambridge also recur, alongside Quincy, Dorchester, Jamaica Plain, and Waltham. Outside Massachusetts, the only recent-state recipient shown is Bethesda, Maryland, for Cystic Fibrosis Foundation.
It gives most often to Boston-area youth-serving organizations, especially independent school support, mentoring programs, and out-of-school-time or summer youth development groups. The recent grants list also includes adaptive sports and student-service organizations, with most awards marked general support.
The foundation’s grant-size distribution is p25 $5,000, median $12,500, and p75 $25,000. Recent awards also include multiple $50,000 grants, showing that some recurring recipients receive larger commitments than the median gift.
Yes. 91% of grants go to recipients in Massachusetts, and the recent grants list is entirely U.S.-based. Recent Massachusetts locations include Boston, Brookline, Cambridge, Quincy, Dorchester, Jamaica Plain, and Waltham.
The pattern is recurring. Bbbs of Mass Bay appears twice in 2025 with $50,000 grants, and The Park School received grants in both 2024 and 2025 across different program lines. That repeated support suggests ongoing relationships with a small set of grantees.
