David Matheson (campaigner)

David Matheson (born 1961) is an American clinical mental-health counselor based in Utah. He is known for his previous advocacy of conversion therapy. In 2019, he announced he was divorcing his wife of 34 years and intended to live as a gay man. He was involved in leadership with People Can Change (now known as Brother’s Road) and co-created the “Journey into Manhood” weekend retreat offered by that organization.

Matheson is sometimes described as a former leader within the “ex-gay” or “sexual-orientation-change-effort” movement. Once referred to by media outlets as “the intellectual godfather” of conversion therapy, he later disavowed the practice, expressing regret for the harm it caused. He currently operates a gay-affirmative counseling practice in Draper, Utah.
