Tarek claims that he is the victim of multiple false allegations of sexual misconduct that have destroyed his life and career.

“These women have tried to tarnish my name,” he says, adding, “What I really want to prove to Dr. Phil through a polygraph exam is that all these women are mistaken, and that I am a professional massage therapist.”

Tarek’s license to practice massage therapy was revoked after more than a dozen clients accused him of everything from inappropriate touch to sexual assault. Watch Thursday’s episode to hear Tarek explain why he says the allegations against him are simple “misunderstandings” and completely false.
