Dr. Robert E. Anderson

ANN ARBOR — Staff at the University of Michigan missed many opportunities to stop a doctor who committed sexual misconduct for decades with long-term consequences for hundreds of patients, including generations of student athletes, a law firm hired by the school reported Tuesday.

The long-awaited report by the WilmerHale firm comes more than a year after former students publicly accused the late Robert Anderson of molesting them during routine physicals or other visits. Some university officials at the time took no action despite being aware of complaints, including legendary football Coach Bo Schembechler, the report said.

Their failure to act allowed Anderson “countless occasions” to harass, abuse and assault patients during his 37-year career, attorneys for the firm wrote.

Anderson was a native of L’Anse.

“He continued to provide medical services to student athletes and other patients — and to engage in sexual misconduct with large numbers of them — for the rest of his career,” the report said.

A January court filing indicated there could be more than 850 victims, which would exceed the number of women and girls who were part of a $500 million settlement with Michigan State University over abuse by sports doctor Larry Nassar. Ohio State University has paid more than $45 million to 185 people who said they were groped by Richard Strauss, another sports doctor.

The law firm’s inquiry found at least 20 occasions when a student, athlete or other individual spoke with university staff about Anderson’s actions. Those accounts either came during interviews conducted by attorneys or from reports made to the university’s Division of Public Safety & Security during its investigation of Anderson’s career.
