|Born||January 21, 1947|
Joseph Nicolosi (born January 21, 1947) is an American clinical psychologist, founder and director of the Thomas Aquinas Psychological Clinic in Encino, California, and a founder and former president of the National Association for Research and Therapy of Homosexuality (NARTH). Nicolosi has advocated and practiced reparative therapy, a practice that he claims can help people overcome or mitigate their homosexual desires and replace them with heterosexual ones.
Nicolosi has described his theories in Reparative Therapy of Male Homosexuality: A New Clinical Approach and three other books. Nicolosi proposes that homosexuality is often the product of a condition he describes as gender-identity deficit caused by an alienation from, and perceived rejection by, individuals of the subject's gender. He holds a Ph.D. from the California School of Professional Psychology. Nicolosi is a founding member of the National Association for Research & Therapy of Homosexuality (NARTH) and was its president for some time. NARTH is a professional association that promotes the acceptance of conversion therapy, whose adherents purport successfully changing homosexuals into heterosexuals. He is an advisor to, and officer of, NARTH.
In 2012, California passed a law that banned the provision of conversion therapy to minors, including some of Nicolosi's existing patients. Nicolosi was named as a plaintiff in a lawsuit challenging the law on constitutional groups but the law, effectively barring Nicolosi's clinic from taking on patients under the age of 18, was subsequently upheld.
In 2015, a New Jersey judge barred Nicolosi from appearing as an expert witness in a lawsuit filed against another provider of conversion therapy on the basis that expert opinions contrary to "the overwhelming weight of scientific opinion" should be not be admissible.
