Joseph Nicolosi (January 24, 1947 – March 8, 2017) was an American clinical psychologist who advocated and practised "reparative therapy", a form of the pseudoscientific treatment of conversion therapy that he claimed could help people overcome or mitigate their homosexual desires and replace them with heterosexual ones.[2] Nicolosi was a founder and president of the National Association for Research and Therapy of Homosexuality (NARTH).[3] Medical institutions warn that conversion therapy is ineffective and may be harmful, and that there is no evidence that sexual orientation can be changed by such treatments.
