PROFILE: The Sidman Family Foundation is steered by the Sidman family, which has strong ties to the Boston area. The foundation's president is Paula Sidman. Paula's father, the late Norman B. Leventhal, was a real estate developer who helped shape the Boston skyline. Paula's husband, the late Edwin Sidman, meanwhile, joined Leventhal's company. The family foundation is also steered by Paula's daughter, Hope Sidman, CEO of H2O Applied Technologies, and Paula's son, Matthew Sidman, founder of hedge fund firm Three Bays Capital. The family foundation’s grantmaking interests include health and human services, Jewish causes, education and youth, and arts and culture.

The foundation's Boston grantmaking involves health and human services organizations, such as Beth Israel Deaconess Medical Center, Brigham and Women's Hospital, Massachusetts Eye and Ear Infirmary, and Children's Hospital Trust, which has received particularly large sums recently. The Sidmans also support Jewish organizations in Boston, forces which involve several generations of family members. The Sidmans, via their foundation, continue to support the JCC of Greater Boston. Other grantees have included and Combined Jewish Philanthropies of Greater Boston, where Edwin once served as chair. The Sidmans help fund education and youth organizations in Boston, such as the Boys & Girls Club of Boston, Jump Start, Neighborhood House Charter School, and Buckingham Browne & Nichols School. Norman Leventhal was active with the United Way of Massachusetts Bay and Merrimack Valley, which the Sidmans have supported through their foundation. The family has also supported local arts and culture in Boston, including the Norman B. Leventhal Map Center at the Boston Public Library. 

Annual foundation giving has ranged from approximately $40,000 to $1 million. Review the funder’s recent tax records to learn more about its local giving.
