15. Saul Katz

As any Mets fan will tell you, Katz and his partner Fred Wilpon are making big moves for their team. But not all fans agree on his choices. Some may say the team’s additions this year may be reason for this power broker to be either bumped up the Power List, while naysayers would like him bumped down a few spots. Aside from the recent high-profile debut of Citi Field, Katz directs Sterling’s day-to-day real estate operations, as well as non-real estate affiliates ranging from financial institutions to manufacturing, consulting, entertainment and retailing enterprises. He also sits on the Board of Renewable Environmental Solutions, a partnership of Changing World Technologies and ConAgra foods that is focused on turning agricultural waste into fuel. That’s in addition to serving as chair of the Board of the North Shore Long Island Jewish Health System, as well as serving as a board member of many nonprofit organizations and institutions.
