When the New Yorker arrived in Vegas in 2000, he had no club experience whatsoever. Starting as a VIP host at the House of Blues, McCormack also worked at Foundation Room, Light at the Bellagio and then Body English at the Hard Rock. Now McCormack has part ownership in Wasted Space, opened Rare 120, Vanity and Johnny Smalls, and says happy employees make for happy customers. “I try to make sure everybody likes their job and make a fun environment for them to work in,” says McCormack. “I wasn’t a nightclub guy,” he says. “I look at it as more of a business: Just like anything else, instead of selling clothes or cheeseburgers we’re selling a party and booze.”
