## About

The Mabel Louise Riley Foundation was formed in 1972 to continue the philanthropic intent of Mabel Louise Robinson, whose career in writing and education generated the estate that funds its work. Co-Trustees Grace K. Fey and Joanne Y. Jaxtimer govern the foundation alongside Fund Director Che Madyun, operating from Boston. The foundation deploys capital primarily through a Family Strengthening Small Grants Fund, channeling resources to nonprofits focused on literacy, digital equity, and neighborhood vitality. Its most significant structural commitment is a decades-long partnership with the Dudley Street Neighborhood Initiative (DSNI), supporting community-led revitalization in Roxbury and Dorchester. The foundation's real-asset exposure includes Dudley Neighbors Inc., a community land trust holding mixed-use property in the Dudley Street neighborhood — a rare direct-ownership model for a foundation of this scale. The investment portfolio itself is managed externally by BNY Mellon. The foundation operates with a lean governance structure; named fiduciaries include Co-Trustee Grace Fey, who also serves on the board of Fiduciary Trust Company and holds memberships in the National Association of Corporate Directors and Board Leaders. The foundation does not publish AUM, but independent estimates place assets near $47 million (Altss estimate). The philanthropic vehicle and the BNY Mellon-managed portfolio remain the sole identified structures — no separate operating company, club vehicle, or donor-advised fund platform is publicly disclosed. The Riley Foundation's structural differentiator is not its asset size but its geography-locked, land-trust-anchored strategy: its grantmaking and real estate holdings are concentrated in a specific Boston neighborhood revitalization effort it has supported for over three decades. This hyper-local posture stands apart from the broader, multi-city programmatic grantmaking typical of similarly sized foundations.

## Questions

### Who runs investment decisions at the Mabel Louise Riley Foundation?

The foundation's investment portfolio is managed externally by BNY Mellon, per Altss research. Governance and strategic oversight rest with Co-Trustees Grace K. Fey and Joanne Y. Jaxtimer, while Fund Director Che Madyun manages day-to-day grantmaking operations.

### Is the foundation a traditional grantmaker or does it take direct stakes in real estate?

It does both. The foundation operates the Family Strengthening Small Grants Fund alongside direct real-asset exposure through Dudley Neighbors Inc., a community land trust in Boston's Dudley Street neighborhood. This hybrid model is unusual for a foundation of its scale and has been sustained over multiple decades.

### How is the foundation related to the Dudley Street Neighborhood Initiative?

DSNI is the foundation's longest-strategic partner and primary grantee. The relationship ties the foundation's philanthropic capital directly to community-led development in Roxbury and Dorchester, with the foundation's real estate exposure concentrated in the same geography through the DNI community land trust.
