Michael Reveles Hospital History

Michael Reveles, 44, was recently charged with second- degree sexual assault of three St. Marys patients.

News 3 has obtained copies of some investigation records on an unrelated matter from the Dane County Sheriff's Department, including new details about Reveles' work history -- and why both Meriter Hospital and a hospital in Illinois also asked him to leave.

Reveles was also fired from his position as a nursing assistant at UW Hospital four years ago for allegedly inappropriately giving backrubs to female psychiatric patients.

Now, News 3 reports that during a 2001 Dane County investigation into an unrelated matter, Reveles himself told detectives he was in "Rockford as a nursing assistant working at St. Anthony Hospital ... " when "a female patient complained about the backrub he had given her ... " ... and that "he was fired."

His work troubles didn't stop there, but followed him to all three Madison hospitals, News 3 reported.

Reveles told detectives he "also had trouble at Meriter Hospital" and that "he was asked to leave."

Meriter Hospital confirms that, telling News 3 Reveles was hired by a temp agency and "not asked back."

Records say between late 2000 and early 2001, he allegedly harassed some nurses, talking constantly about sex, and calling them at home. At least one nurse filed a formal hospital complaint, while a second told her manager, "Reveles made her feel 'uneasy,'" she reported.

He talked about sex with his girlfriends and ex-wife ... about meeting girls on the Internet and made provocative comments about other nurses on the staff, according to the complaint.

The investigation never led to any charges, but Reveles claimed he'd been falsely accused at Meriter.

He's also denied the allegations at St. Marys and at UW Hospital, which News 3 reported broke state law by not reporting suspected abuse to the state years ago.

Reveles has been enrolled at MATC since 2001. He told detectives he wants to become a registered nurse.
