Offering Psychological Services to Men and Women Whose Same-sex Attraction Doesn't Define Them



For many years, I have been assisting men and women –mostly, persons who are still at a crossroads about their sexual identity– to reduce their same-sex attractions and explore their heterosexual potential.

I am a licensed clinical psychologist who shares your vision of humanity. I believe that our bodies tell us who we are, and that our bodies have made us for heterosexuality.

Perhaps you experience same-sex attractions, but you believe you were not destined to be gay. You believe that these feelings do not represent “who you really are.”

If this is your belief, then we may be able to help you.

I have helped many men reduce their unwanted same-sex attractions, so that they lose their compelling, life-disrupting power, and assisted them in exploring and developing their heterosexual potential.

The Science Behind Our Work

In 1992, I and two psychiatrists organized a professional association called the National Association for Research and Therapy of Homosexuality (NARTH). Today, NARTH has over 1000 members around the world.

In What Research Shows: NARTH's Response to the American Psychological Association’s Claims on Homosexuality.” This paper examines over 100 years of scientific literature on the subject of overcoming unwanted sexual attractions; it offers substantial evidence that for at least some people, sexual orientation can be modified.

Dr. Joseph Nicolosi, Sr. (1947 - 2017)

          We are deeply saddened to announce that Dr. Joseph Nicolosi, Sr. passed away unexpectedly on March 8, 2017.

          The Thomas Aquinas Psychological Clinic has therefore closed down its psychotherapy practice.

          Although our practice is closed, there are several other therapists in their own private practices, trained by Dr. Nicolosi, to whom we can refer you. Please email our office for information. These therapists share your worldview and support your sense of who you were meant to be. You can email us at

          We will also continue to make available to anyone interested in understanding Dr. Nicolosi's lifetime of work and thought. The articles he wrote on this web site have timeless value.  He is the originator of reparative therapy, and these articles, as well as the four books he wrote, will live on in the history of psychotherapy.
