17. Saul Katz

Presiding over real estate and retail at Great Neck-based Sterling Equities is not enough for this CEO/CPA: the Glen Cove guy’s got a throwing arm in baseball as president of both the New York Mets and Brooklyn Cyclones. The GOP financier headed Dem Tom Suozzi’s transition team after Suozzi became county exec, and was tapped by Suozzi to consolidate Nassau’s real estate holdings and ailing county buildings. A donor to the LI Children’s Museum, ERASE Racism and other regional organizations, Katz was the first chairman of North Shore-Long Island Jewish Health System, helped form the mighty healthcare system and has returned as its chair.
