 In 2006, a gymnast who trained at Liukin's World Olympics Gymnastics Academy (WOGA) filed a lawsuit alleging that Liukin and co-owner Yevgeny Marchenko had failed to properly screen and supervise her coach Christopher Wagoner who, according to the gymnast, sexually assaulted her numerous times and suggested that she use cocaine for weight loss.Gymnast Katelyn Ohashi has alleged multiple times that Liukin and Marchenko's coaching style contributed to an eating disorder and deep unhappiness that ultimately lead her to retire from elite gymnastics after her injury.On 16 September 2016, he was named the coordinator for the United States women's national gymnastics team, replacing the retiring Márta Károlyi.
