When Thomas and Cindy Kocian think about daughter Madison's gymnastics career, they can reflect on her scores of medals, international travels and the Rio Olympics, where the Dallas native won gold and silver medals in 2016.

But the accomplishments aren't worth it, Kocian's parents said, because their daughter says she was sexually abused by USA Gymnastics team doctor Larry Nassar under the guise of medical treatment. In pursuit of her Olympic dream and in the sport's intense culture, Kocian said she was afraid to speak up.

Kocian, who trained at World Olympic Gymnastics Academy in Plano throughout her seven-year elite career and now competes for UCLA, came forward Thursday to say publicly for the first time that she's among the more than 200 women and girls to have suffered abuse by Nassar. She spoke alongside 2012 Olympic gold medalist Kyla Ross, now her UCLA gymnastics teammate, on CBS This Morning and to The Associated Press.

Nassar is serving an effective life sentence after being convicted on federal child pornography and state sexual abuse charges.

"You always want to protect your child and do what you can for them, and to me, at this point, no it was not worth it," Thomas Kocian told The Dallas Morning News in a phone interview Thursday. "That's based on what she's going through now, what she has been through since age [12] when she first made national team."

Kocian, 21, through her lawyers has served notice of a civil lawsuit against Michigan State University, which employed Nassar for decades, according to Stu Mollrich, a media consultant for the law firm of Manly, Stewart & Finaldi. Kocian's lawsuits against USA Gymnastics and the U.S. Olympic Committee will come "shortly," Mollrich said.

Kocian is "a very internal person," her dad said, so "it probably took her longer to process what actually happened to her." She watched in January as more than 100 women and girls spoke in front of Nassar during one of his sentencings and felt ready now to "get this off her chest, help her healing process," Thomas said.

All five members of the 2012 Olympic team -- Ross, Jordyn Wieber, Aly Raisman, Gabby Douglas and McKayla Maroney -- have said they were abused by Nassar. Kocian is the fourth member of the 2016 Olympic team to come forward, joining Raisman, Douglas and Simone Biles.

Kocian's parents were exceptionally critical of USA Gymnastics, the sport's national governing body, for fostering what they called a fear-based, secretive environment with little communication.

From when she made the national team at 12 years old through her final elite competition at the 2016 Olympics at 19, Kocian traveled to training camps almost every month at Bela and Martha Karolyi's ranch in Huntsville. The facilities were deep in the woods and had little cellphone reception. Parents weren't allowed to accompany their athletes.

When Kocian represented the U.S. at international competitions -- which included two world championships, the 2016 Olympics and spanned multiple continents -- the Kocians set up an international phone plan to allow her to text and call.

But her regimented schedule in training, recovery and competition left little time for talking. Though the Kocians often traveled to watch from the stands, they weren't permitted to interact with their daughter before meets or stay in the same hotel.

During many of those outings and camps, Nassar was the team doctor. Other victims have spoken about abuse occurring in their hotel rooms and training camp cabins. USA Gymnastics cut ties with Nassar in 2015, about a year before Kocian's Olympic performance, after receiving complaints about his conduct.

Other gymnasts, including Kocian's 2016 Olympic teammate Raisman, have said they were questioned by an investigator hired by USA Gymnastics in that year, but Kocian's parents said the organization never alerted or questioned them about the concerns regarding Nassar.

"Nobody ever called to check on our child," Cindy Kocian said. "Since she was 12 years old, she's represented them. And yet they could never call to check to see if she was harmed or how she was doing, even after they began investigating [and] they had heard her teammates were harmed."

In a statement to CBS This Morning, the governing body said: "USA Gymnastics' support is unwavering for Kyla, Madison and all the athletes who courageously came forward to share their experiences. Their powerful voices and stories will continue to be a basis for our future decisions."

But the Kocians aren't satisfied.

"We never heard anything about any of it until after Rio," Cindy said. "And then they still haven't even contacted us."

"How is that support?" Thomas said.

"There are still people at the top that I feel have overseen this issue for a long time and I think that needs to be changed as well as the whole culture around everything," Kocian told the AP. "I don't think enough has been changed from the coaching standpoint. There are still coaches under that abusive style of coaching, whether it's verbal abuse, that's what enables all of this."

The Kocians, however, praised the backing of their daughter's personal club coaches at WOGA, Laurent and Cecile Landi, and her UCLA teammates and coaches, with whom she won an NCAA team national championship last spring.

"You live under a fear of not being able to speak up," Kocian told the AP of her elite experience, "because this was our only avenue to accomplish our dreams."
