The director of a nonprofit that offered so-called gay conversion therapy is testifying in a consumer fraud lawsuit.

Arthur Goldberg headed the Jersey City-based Jews Offering New Alternatives for Healing when it was sued in 2012 by four men. They underwent treatment they say they were told would turn them from gay to straight.

The men claim the group, known as JONAH, violated New Jersey consumer-protection laws by making fraudulent claims and misrepresentations about what it could do.

The 75-year-old Goldberg told jurors Monday that he doesn't have a degree in medicine or psychology.

Earlier, one of the plaintiffs admitted on cross-examination that he had positive feelings about the program at the time he discontinued therapy.
