NET WORTH: Unknown

SOURCE OF WEALTH: Mack Real Estate Group, Solon Mack Capital

FUNDING AREAS: Health & Human Services, Education & Youth

OVERVIEW: Stephen Mack and his wife Kelly move their philanthropy through the Stephen Mack and Kelly Mack Family Foundation. Giving focuses on health, including NYU Langone Medical Center. Another interest is education. 

BACKGROUND: Stephen Mack graduated from the University of Pennsylvania and received an M.B.A. degree from Columbia. He was a managing partner of WRS Advisors III and MVG Holdings, businesses in New York that invest in technology and internet companies. His father, William Mack, is a real estate mogul and the family established Mack Real Estate Group in 2013.  The family also steers Solon Mack Capital, an investment office involved in a number of different industries.


HEALTH & HUMAN SERVICES: The couple supports NYU Langone Medical Center, including the Stephen D. Hassenfeld Children’s Center for Cancer & Blood Disorders. Mack is a trustee of NYU Langone Health and Kelly is on the committee for the Stephen D. Hassenfeld Children’s Center. Other grantees include Food Allergy Research & Education (FARE); Musicians On Call, which brings live and recorded music to the bedsides of patients in healthcare facilities; Lung Cancer Research Foundation; and Sanctuary for Families.

EDUCATION & YOUTH: The Mack foundation has supported The East Harlem School and Turn Around for Children.

OTHER: The couple has directed funds to Monterey Peninsula Foundation, American Friends of Israel Museum, and Randall's Park Alliance.

LOOKING FORWARD: The Macks' giving via their foundation hasn't been overwhelming recently, but both the Macks are still very much engaged in their real estate business. Perhaps more money will move out in the coming years. The couple's schools, UPenn, Columbia, NYU, and Georgetown, may yet see strong support.
