Former gymnast Mattie Larson said all she wanted to do when she was a kid was go to the Olympics.

But to do so, she felt pressured to do several things she didn't want to do - including going to Karolyi Ranch, where she said she was abused multiple times by ex-doctor Larry Nassar.

In a statement to the Ingham County Circuit Court during Nassar's sentencing hearing on criminal sexual abuse charges, Larson said the ranch was "the perfect place for abusers and molesters."

The ranch is owned and operated by coaching legends Marta and Bela Karolyi. At least a half-dozen elite gymnasts say they were abused there by Larry Nassar, former doctor for the national team and the head medical professional at USA Gymnastics.

By the time she was 15 or 16, Larson, a former elite gymnast, said she would get panic attacks before going to the training center, because Nassar, her coaches and USA Gymnastics "turned the sport I fell in love with as a kid into a living hell."

Larson said she was first abused by Nassar in her first U.S. National Championship competition when she was 14. She sustained a painful hip injury close to her pelvic bone, and said Nassar inserted his fingers into her vagina for the first time during treatment for that injury.

That abuse continued "almost every single time" Nassar treated her after that, she said.

"No matter what he was supposed to be treating...his fingers always seemed to find way inside me, never once wearing gloves."

Once, Larson said she sprained both ankles at one time. Nassar said she was fine, but she could barely get around through the rest of the training. Back home, her doctors checked X-Rays, and came to the opposite conclusion.

Like many other gymnasts, Larson said she appreciated Nassar's kind demeanor, telling the court she was one of the only nice adults she knew at the time. She said when she was at the ranch, Nassar used to abuse her in the lounge where all of her teammates were watching television, and often around her coaches and trainers.

"If he is doing this in front of my friends, it can't be that bad, right?" she said she remembered thinking.

"Larry, you were the only one I trusted," Larson said in the courtroom. "In the end, you turned out to be the scariest monster of all."

Larson said the scars remain from her gymnastics career, describing an eating disorder she went through and the grueling practice schedule that often left her without food or water for six to seven hours at a time, six days a week while practicing.

The ranch, though, was one of the worst parts of gymnastics, Larson said. At one point, she said she faked an injury by pushing the bath mat in her bathroom aside, getting on the floor and banging her head hard enough to get a bump to try and get out of going.

"I was willing to physically hurt myself to get out of the abuse I received at the ranch," she said.

Larson said she hopes USA Gymnastics and MSU are held accountable, and hopes legislation to help prevent this from happening to anyone else.

To Nassar, she said she couldn't believe how she used his kindness as a ploy to molest her and her friends at every chance he got.

"I can't even put into words how much I f***ing hate you," she said. "No accolade or award is worth enduring abuse."
