About William & Sheila Konar Foundation C/O Ann Marie Mahoney
A defining thread in the William & Sheila Konar Foundation c/o Ann Marie Mahoney’s recent giving is its repeated support for Holocaust education and antisemitism prevention. The U.S. Holocaust Memorial Museum received $1.24 million in both 2023 and 2024 for its Denial & Antisemitism Initiative, signaling a sustained commitment rather than a one-time gift. That same pattern of continuity appears in Rochester, where the foundation has backed Jewish Federation of Greater Rochester, Jewish Family Services, and the JCC of Greater Rochester across multiple years. The foundation also makes major higher-education gifts, including an endowment for the Warner School of Education in Rochester, and it has supported health research through a large grant to the Alzheimer’s Association. Its recent portfolio combines large institutional grants with local community investments, including emergency-response support, school-related programming, and Jewish community services. The overall picture is of a local funder with selective, high-dollar commitments that move across Jewish life, education, civic initiatives, and health research.
