Dr. Dimitri Douchin

Dimitri is a Pornography Addiction Recovery Coach and recovered addict. Dimitri helps high-achieving men and their partners heal from their toxic relationship with pornography and live a happy and purposeful life.

“I had been an addict for 16 years, when, convinced I would be an addict for life, I started looking into ways I could use my addiction in a constructive way. “

Dimitri began to study the nature of addiction and its effects on the mind and relationships.

“Six months later, I was healed. After 17 years of struggle, I was finally free. Goodbye wasted hours, feelings of guilt, loneliness, shame, inadequacy, low self-esteem, failure at communicating.”

Since then, Dimitri has coached hundreds of men out of their toxic relationship with pornography, healing their core trauma and live a meaningful life.

In his treatment protocol, he uses a method that allows for progressive deconditioning away from pornography. My clients also work on successfully integrating the shadow / wounded child through Transactional Analysis, trauma reprocessing and sexual fantasies analysis.

Prior to becoming a highly acclaimed coach he had completed his PhD in Astrophysics at Macquarie University.

Dr. Sarah Melancon, Ph.D

Sarah Melancon, Ph.D is a Sociologist and Clinical Sexologist.  Growing up with severe social phobia and a communication disorder called selective mutism, Sarah was equally fascinated and confused by human relationships – ESPECIALLY sexual relations.

Her research spans the fields of sociology, psychology, sexology, trauma and neurobiology.  Sarah believes that while our sexual desires can be a path to greater intimacy and connection, they also reveal our deepest fears, hopes, dreams and traumas that we keep hidden in the shadows.  By cultivating awareness, learning self-compassion and healing the underlying traumas endemic to modern society, our most hidden corners of shame can become our greatest sources of power to create the authentic, loving and pleasure-filled relationships we truly deserve.
