Overview

The Popplestone Foundation was established in 2000 by Alan Dworsky (1930-2021), a former investment firm principal, and his wife Suzanne. The foundation has grown substantially in recent years, with 2023 marking exceptional growth in grantmaking activity—from $23.5 million in 2022 to $145.3 million in 2023. With total assets of $78.2 million as of 2023, the foundation demonstrates an extraordinarily high payout rate. The foundation's strategic focus has evolved from its original emphasis on education, human services, and performing arts to now primarily supporting policy advocacy organisations, particularly those focused on social welfare programme expansion, voting rights, civil liberties, and health equity.

Funding Priorities

Grant Programmes

The foundation operates a single discretionary grantmaking programme managed by its trustees. Individual grants in recent years have ranged from $50,000 to $5,000,000, with a median award of approximately $296,650.

Application Method: Invitation only—the foundation makes contributions exclusively to preselected charitable organisations identified by trustees.
