Kacy Catanzaro rose to national prominence as the undisputed star of NBC’s American Ninja Warrior. Kacy’s historic run in the 2014 Dallas City Finals changed the narrative of what was possible for women on the course. She also held the honor as the first woman to qualify for the Las Vegas Finals and to complete a City Finals course. Catanzaro has served as a host on Team Ninja Warrior and acted as a coach to “Arrow” star Stephen Amell on American Ninja Warrior. Kacy’s knowledge of gymnastics and her ninja prowess translated naturally to Alpha Warrior.
