Employees in the athletic department and health service department at the University of Michigan missed warning signs and failed to stop the serial sexual misconduct of former school doctor Robert Anderson, according to a report from the WilmerHale law firm released Tuesday afternoon.

The university hired WilmerHale in March 2020 to investigate allegations of sexual misconduct against Anderson as well as the response that patients received from other employees when they made complaints about Anderson. Investigators interviewed more than 300 former patients and more than 200 university employees during a 14-month investigation before publishing a 240-page report Tuesday. They found that Anderson engaged in sexual misconduct on “countless occasions” and that authority figures heard specific accusations as well as rumors about Anderson’s misconduct but failed to stop him from abusing others.

Anderson worked at the University of Michigan from 1966 through 2003. During the majority of his time at the school he worked closely with the athletic department, treating athletes’ injuries and conducting annual physicals. Hundreds of former patients — many of them former Wolverine athletes — now say that Anderson sexually abused and harassed them in a variety of ways during the treatment of routine medical issues. In interviews and court documents, Anderson’s former patients say the doctor assaulted them, fondled them and made an array of inappropriate sexual comments, among many other examples of misconduct.

Anderson died in 2008 before the claims of abuse were widely publicized.
