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.

The New U.S. Supreme Court Ruling: Freedom to "Define and Express Your Identity"

The U.S. Supreme court recently ruled that Americans have a constitutional right to "define and express their identity." This ruling -- which was the basis of the Court's Same-Sex Marriage ruling-- cannot justly be withheld from people with a different goal: men and women who seek to change their sexual identity. So if homosexuality is not who you really are, then you, too, have a right to live in accordance with your values, and to seek whatever degree of change in identity, behavior and attractions is possible for 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.
