John Catsimatidis's family moved from Greece when he was an infant and has been buying real estate for decades. Now—as the owner, president, chairman, and CEO of Gristedes Foods, the largest grocery chain in Manhattan, and the Red Apple Group, a real estate and aviation company—John has gained a sizable empire himself with about $700M to $800M in holdings in New York, Florida and the US Virgin Islands. He also owns more than 375 gas stations and convenience stories—under the QwikFil and Country Fair brands—as well as an oil refinery in Pennsylvania.
These days, when he’s not running the Hellenic Times or hosting his radio talk show, John’s developing an apartment and retail complex in Ft. Greene, Brooklyn. But he’s best known to New Yorkers for his mayoral campaign in 2013, where he lost the Republican primary. He continues to be a massive supporter of Republican candidates like Marco Rubio.
