Paris Hilton's shrink needs a thorough examination.

First Dr. Charles Sophy got Hilton out of testifying in a $10 million slander suit against her by socialite Zeta Graff, arguing that Paris is too "emotionally distraught and traumatized" by her incarceration to testify. Then the Beverly Hills healer paid an unauthorized visit to Hilton in jail and somehow helped secure her release (albeit temporary) just three days into her 45-day sentence. How, exactly, he swayed L.A. County officials to go easy on the heiress (against judge's orders) is a mystery many members of the media would like answered. Sophy, however, has stonewalled, and now Radar has discovered that the tight-lipped doc's résumé and past ethical dealings are as shady as his persuasive legal hocus-pocus.

Until yesterday, for example, Sophy claimed on his website to hold an "Associate Clinical Professorship at the University of California, Los Angeles, Neuro-Psychiatric Institute." He does not. According to well-placed sources at UCLA, he's an unpaid volunteer clinical instructor—"an entry-level position at best," the source tells Radar. "He cannot claim himself to be a professor here by any means."

Sophy has yet to return Radar's messages seeking comment, but it seems our probing reached him. He changed his website late Wednesday. It now says he's "a clinical instructor" at UCLA rather than a proper professor. [Before and after screen grabs after the jump.]

Also, Sophy has been mistakenly referred to as an M.D. (specifically by Men's Health). He's a D.O., a doctor of osteopathy, a slightly different classification, though D.O. schooling and training mirrors that of M.D.s. Osteopaths focus on alternative treatments, prevention, and patients' total wellness rather than specific symptoms. And osteopathic psychiatrists make up about 10 percent of the American Psychiatric Association, of which Sophy has been a member for more than a decade. So why wouldn't he be forthcoming about his exact credentials?

"Some of the D.O.s in our organization don't go out of their way to make the distinction," says a spokesperson for the American Osteopathic Association. "It's a personal choice, but I don't know why any D.O. would not want that to get out."

This isn't the first celebrity case for Sophy, who's also a go-to medical expert for PBS and Fox. He famously agitated on behalf of Michael Jackson during the king of pop's 2003 molestation trial. Shortly after Sophy was hired as the medical director of L.A. County's Department of Children and Family Services (a position he still holds), he raised eyebrows by ordering up a memo that seemed to exonerate Jackson. Soon after the confidential document landed on his desk, it was posted on the Smoking Gun and was subsequently used by the pop star's attorneys and media supporters to plead his innocence.

The memo might have helped Jackson, but Sophy was accused of leaking it, a charge he denies. "I'm involved in the Jackson case ... but not the way that you think," Sophy told Celebrity Justice. The incident continues to dog him years later.
