Sean McCormack

Sean McCormack is the Executive Director of Poker Strategy and Development at MGM Resorts International, overseeing the company’s domestic poker portfolio of nine rooms across six states, including iconic Las Vegas properties such as ARIA, Bellagio, and MGM Grand. He leads strategic alignment and development for the entire poker division.

McCormack joined MGM Resorts in November 2006 as a poker dealer at Bellagio after relocating from Florida, where he had dealt at the Daytona Beach Kennel Club and worked a traveling World Poker Tour stop. Before entering the poker industry, he studied computer science in college and expected a career in technology, but his move to Florida led him to playing and dealing poker, which ultimately brought him to Las Vegas.

His interest in the business side of poker caught management’s attention, leading to a promotion to Director of Poker Operations at ARIA in January 2016. He later advanced to his current executive role, which was attested by 2026. McCormack describes himself as competitive and a longtime gamer, and he now shapes the strategy for one of the largest poker operations in the United States.
