Report: UM officials did not heed 'credible reports' of abuse by Anderson View Comments More than two dozen University of Michigan employees were alerted to reports of sexually inappropriate behavior by former university Dr. Robert Anderson, reports that could have stopped the doctor who is accused of molesting more than 800 men, according to a highly anticipated report released Tuesday. The 240-page report, commissioned and paid for by UM, concluded Anderson sexually abused patients, 90% of whom were men, on "countless occasions." Anderson is the former head of University Health Service, and later, team physician for the college's Athletic Department. He worked for UM from 1966 to 2003. He died in 2008.
