Conversion therapy (also referred to as reparative therapy) is the practice of attempting to change the patient’s sexual orientation to heterosexual.  Among the most prominent supporters of conversion therapy is the National Association for Research & Therapy of Homosexuality (NARTH), which continues to characterize homosexuality as a mental disorder, despite the declassification of homosexuality as a disorder in the Diagnostic and Statistical Manual of Mental Disorders (DSM) in 1973.[3] One of the most notable members of NARTH is founder and former president Dr. Joseph Nicolosi, who practices conversion therapy and has published case studies some of his clients.[4]
