Biographical Information

Joseph Nicolosi, Ph.D.  1947 - 2017

Dr. Nicolosi graduated from the New School for Social Research (M.A.) and received his Ph.D. in Clinical Psychology from the California School of Professional Psychology, Los Angeles. He was licensed as a psychologist in California.  He passed away suddenly in 2017.

Dr. Nicolosi was a pioneer in the history of psychology.  His profession was fast abandoning the classic understanding of sexuality as being rooted in design and purpose-- i.e.,  "normality is that which functions in accordance with its design," -- but he refused to be carried along with the tide. Although quite a few colleagues professed agreement with him in private, only a very few were willing to say so publicly. There was always a steep career cost to be paid for disagreeing with the gay lobby. But Dr. Nicolosi was undeterred; he continued to promote the classic understanding of homosexuality as an attachment loss rooted in trauma.  He found support for this view in the rich trove of psychodynamic literature and in research on attachment and individuation. At the time of his death, he was working on a book that would revive this now-abandoned body of case studies and psychoanalytic literature written by the founding fathers and mothers of his profession.

In 1980, he founded the Thomas Aquinas Psychological Clinic in Encino, California, and  served  as Clinical Director. Although he worked with a wide variety of clients, his specialty was the treatment of men who wished to diminish their same-sex attractions and develop their heterosexual potential.

Dr. Nicolosi was one of three founding members--and former President--of the National Association for Research and Therapy of Homosexuality (NARTH), a 1,000-member professional association founded in 1992 (www.narth.com). NARTH’s goal is –

  • To support mental-health professionals who work with same-sex-attracted clients seeking change.
  • To promote respect within the mental-health profession for worldview diversity—whether a person seeks to identify as gay, or to work toward developing his heterosexual potential.

The NARTH website is viewed by over 100,000 visitors each month. It is the only secular group in the U.S. which protects the rights of therapists to counsel clients with unwanted homosexuality.
