Mattie Larson was a consistent star in the world of gymnastics over the course of her athletic career, qualifying and competing for the most prestigious teams around the world at the highest levels. In 2018, along with 156 other women, Mattie courageously testified against Larry Nassar, her former US National Team Gymnastics doctor and serial sexual assaulter. As a result of this trial, which was one of the largest sexual assault investigations in US history, Nassar was sent to prison on account of hundreds of sex crimes. After the trial, Mattie went on to pass and amend bills with the US Congress in Washington, DC, to increase the protections of children from sexual assault. Testifying face-to-face with her abuser in court was one of the most difficult things Mattie has had to face, however, speaking her truth re-instilled her sense of self-worth and confidence that had been lacking for so long.
