Shortly before the 2011 Pan American Games in Guadalajara, Mexico, she was partnered with Mary Killman to compete as a duet. At those games, Killman and Koroleva won a silver medal in the duet competition, and were members of the United States team that won a silver in the team competition as well. The pair qualified for the women's duet at the 2012 Summer Olympics in London, and due to the failure of the United States to qualify for the team event, they were the only American women to compete in synchronized swimming at those games.
