Joseph Nicolosi, Ph.D.
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 is licensed as a psychologist in California.
In 1980, he founded the Thomas Aquinas Psychological Clinic in Encino, California, and has served since then as Clinical Director. Although he works with a wide variety of clients, his specialty is the treatment of men who wish to diminish their same-sex attractions and develop their heterosexual potential.
Dr. Nicolosi is 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.

The Joseph Nicolosi Early Career Scholarship Award
Every year the Joseph Nicolosi Student Scholarship Award is given by NARTH (National Association for Research and Therapy of Homosexuality) to a student who has made a significant contribution in research furthering the Association’s goals and objectives. This is one way NARTH can encourage the next generation of mental-health professionals to carry on its mission.
NARTH seeks to express its support and appreciation to students willing take an unpopular stand for what they believe is for a greater good.
