Numerous people have been charged, fired or forced out of their jobs during the investigations into the once-renowned sports doctor. He was sentenced to decades in prison after hundreds of girls and women said he molested them under the guise of medical treatment, including while he worked for Michigan State and Indiana-based USA Gymnastics, which trains Olympians.
Here's a look at some of the individuals and organizations that have been affected:
MICHIGAN STATE UNIVERSITY
— Lou Anna Simon: The university president and school alumna resigned in January 2018 amid growing pressure. She denied any cover-up by the university. She since has been charged with two felonies and two misdemeanors. She is accused of lying during an interview last year when investigators were trying to determine how Nassar got away with sexual assault for so long.
The MSU governing board later hired former Michigan Gov. John Engler. He resigned amid fallout from remarks he made about some victims of Nassar and was replaced by Satish Udpa , the school's executive vice president for administration.
In May, MSU named Dr. Samuel Stanley Jr., a medical researcher who has led Stony Brook University in New York for nearly a decade, as its next president.
The school has settled lawsuits totaling $500 million.
— Mark Hollis: The athletic director called his departure last year a retirement, but he, too, faced pressure to leave.
— Kathie Klages: The former head gymnastics coach resigned in 2017 after she was suspended for defending Nassar over the years. Klages was charged with lying to investigators. If convicted, she could face up to four years in prison. She has denied allegations that former gymnast Larissa Boyce told her that Nassar had abused her in 1997, when Boyce was 16.
— Brooke Lemmen: The former school doctor resigned in 2017 after learning the university was considering firing her because she didn't disclose that USA Gymnastics was investigating Nassar. A state Department of Licensing and Regulatory Affairs investigation cleared her of any violations in November.
— Strampel: The former dean of the university's College of Osteopathic Medicine was charged in March 2018 amid allegations that he failed to keep Nassar in line, groped female students and stored nude student selfies on his campus computer. Strampel, who has also been named in lawsuits, retired June 30, even as Michigan State was trying to fire him. He was found guilty Wednesday of neglect of duty but acquitted on a more serious criminal sexual conduct charge.
— Bob Noto: The university in February 2018 announced the departure of its longtime vice president for legal affairs. The school called it a retirement. Noto had been Michigan State's general counsel since 1995.
— Rhonda Faehn: The former senior vice president of the organization was dismissed in January by the University of Michigan after working for just a few days as a coaching consultant for its women's team. She was fired after an outcry over her hiring. USA Gymnastics parted ways with Faehn as senior vice president in May 2018 after she was criticized by Nassar's victims for not contacting authorities about potential abuse concerns.
— Valeri Liukin: The coordinator of the women's national team for USA Gymnastics announced in February 2018 that he was stepping down, less than 18 months after taking over for Martha Karolyi. Liukin said that while he wanted to help turn around the program, "the present climate causes me, and more importantly my family, far too much stress, difficulty and uncertainty."
— USA Gymnastics said in January 2018 that its entire board of directors would resign, as requested by the U.S. Olympic Committee. The USOC then took steps to decertify the gymnastics organization that picks U.S. national teams, and USA Gymnastics filed a Chapter 11 bankruptcy petition as it attempted to reach settlements in the dozens of sex-abuse lawsuits it faces and to forestall its potential demise at the hands of the USOC.
— Steve Penny: The former president and CEO of the organization resigned under pressure in March 2017. He was replaced by Kerry Perry, who took over in December 2017. Penny pleaded not guilty in October to a third-degree felony alleging he ordered the removal of documents relating to Nassar from the Karolyi Ranch in Texas.
— Less than a year after being hired as USA Gymnastics' president and CEO, Perry resigned in September after the USOC questioned her ability to lead the scandal-rocked organization.
— Former California U.S. Rep. Mary Bono was hired in October as the interim president for USA Gymnastics only to resign four day later. Bono said she felt her affiliation with the embattled organization would be a "liability" after a social media post by Bono criticizing Nike and former San Francisco 49ers quarterback Colin Kaepernick drew widespread scrutiny within the gymnastics community. Six-time Olympic medalist Aly Raisman also questioned Bono's association with a law firm that advised the organization on how to handle portions of the Nassar scandal.
— Ron Galimore: The longtime USA Gymnastics chief operating officer resigned in November but denied any wrongdoing in the Nassar scandal. The Indianapolis Star reported in May that an attorney hired by USA Gymnastics directed Galimore to come up with a false excuse to explain Nassar's absence at major gymnastic events in the summer of 2015. The organization was looking into complaints against Nassar at the time.
TWISTARS GYMNASTICS CLUB
— John Geddert: The owner of the Michigan club was suspended last January by USA Gymnastics and announced his retirement. He was the U.S. women's coach at the 2012 Olympics. Geddert has said he had "zero knowledge" of Nassar's crimes.
— USA Gymnastics said in January 2018 that the Texas ranch where a number of gymnasts said Nassar abused them would no longer serve as the national training center. Owners Martha and Bela Karolyi have since sued the USOC and USA Gymnastics, seeking damages for a canceled sale of the property. They also have been named in lawsuits.
— Debra Van Horn: Texas prosecutors in June filed sexual assault charges against Nassar and Van Horn, a trainer who worked at his side at the Karolyi Ranch and also worked at USA Gymnastics for 30 years. She was charged with second-degree sexual assault of a child. The local prosecutor said Van Horn was charged with "acting as a party" with Nassar.
U.S. OLYMPIC COMMITTEE
— Scott Blackmun: The CEO resigned in February 2018, citing difficulties with prostate cancer and the federation's need to move forward to deal with the sexual abuse scandal. There had been calls for his departure.
— Alan Ashley: The USOC fired the chief of sport performance in December in the wake of an independent report that said neither he nor Blackmun elevated concerns about the Nassar allegations when they were first reported to them.
