WEST LINN, Ore. (AP) — West Linn police say they’re investigating criminal allegations against former West Linn Dr. David Farley, whose Oregon medical license was revoked this month amid patient complaints of sexual abuse.

Four people this month filed a civil lawsuit against Farley, alleging he groped and fondled them during medical exams. The Oregonian/OregonLive reported.

West Linn Detective Tony Christensen has been assigned to the case.

The lawsuit was filed in Multnomah County Circuit Court by the patients who were between the ages of 13 and 28 at the time of the alleged abuse. Farley touched their genitals without wearing gloves and fondled their breasts “under the guise” of performing examinations, according to the lawsuit.

Farley opened the Family Health Center in 1993. He announced his sudden retirement in August, citing “personal reasons,” and no longer is affiliated with the West Linn medical center, police said. Farley also had worked at Legacy Meridian Park Medical Center in Tualatin and Willamette Falls Medical Center in Oregon City.

On Oct. 2, the Oregon Medical Board revoked Farley’s medical license after finding Farley engaged in “unprofessional or dishonorable conduct and gross or repeated acts of negligence.”

The board also barred him from reapplying for one, according to board records.

Farley’s lawyer, Karen O’Kasey, on Wednesday did not return phone or email messages seeking comment.
