And that is one reason she is coming forward to say she was also sexually abused by USA Gymnastics doctor Larry Nassar.
Raisman, 23, said she thought team doctor Larry Nassar, who spent almost 30 years with the organization and began treating her when she was just 15, was providing medical care.
Olympic gymnast Aly Raisman says she is among the young women abused by a former USA Gymnastics team doctor.
Raisman revealed the sexual abuse by Nassar in a preview on Friday of an interview to be aired in full on Sunday on the CBS show "60 Minutes".
In an interview with The Associated Press in August, Raisman didn't want to say whether she had been abused by Nassar, but she called him "a monster" and blamed USA Gymnastics for not stopping him.
The gold medalist said she had no idea that Nassar, who has also been accused of sexual abuse by McKayla Maroney, Raisman's teammate from the 2012 London games, gained their trust by building an emotional bond with the athletes. He is scheduled to be sentenced on federal child-pornography charges on November 27 in MI.
Nassar was the USA Gymnastics' team physician for almost 20 years, beginning in 1996.
The 23-year-old Raisman has been highly critical of USA Gymnastics in recent months, calling for leadership change at the top of the organization while advocating for athlete's rights.
More than 130 women have accused Nassar of sexual assault.
The sex abuse scandal led to the ouster of USA Gymnastics CEO Steve Penny, who resigned in March under pressure from the U.S. Olympic Committee. He stepped down in 2014 but remained on staff before being fired in 2015.
At the 2011 world championships, Maroney said Nassar gave her a sleeping pill "and the next thing I know I was all alone with him in his hotel room getting a 'treatment.' I thought I was going to die that night". His lawyers did not respond to requests for comment, "60 Minutes" said. I can't ... every time I look at them, every time I see them smiling, I just think - I just want to create change so that they never, ever have to go through this. "And I think that needs to be communicated to all of these athletes, no matter the age", she said.
DR. JON LAPOOK: You're angry. A third Olympian, Sydney bronze medalist Jamie Dantzscher, has also said she was abused by Nassar.
In June, USA Gymnastics said it was adopting all 70 of the recommendations from an independent review of its policies related to sexual misconduct.
In July, the organization hired Toby Stark, a child welfare advocate, as its director of SafeSport. Prosecutors have recommended that he be given a prison sentence of between 22 and 27 years. USA Gymnastics now has the power to withhold membership from clubs that decline to report claims of abuse.
The organization has taken some steps to provide more oversight and safety to its national team gymnasts. USA Gymnastics announced this week that Kerry Perry, formerly the vice president of business development at Learfield Communications, would start as CEO on December 1. Perry starts December 1.
In a statement to 60 Minutes, USA Gymnastics pointed to its new guidelines and said it "is very sorry that any athlete has been harmed ... we want to work with Aly and all interested athletes to keep athletes safe".
