This approach was developed by Dr. Andrew Tatarsky, director of the Center for Optimal Living in New York City. Harm Reduction Psychotherapy is effective in treating substance misuse, other risky and addictive behaviors, and mental health challenges such as depression, anxiety, and trauma. Mike helps clients develop practical skills and strategies to manage urges, cravings and difficult emotions, based on mindfulness and other empowering self-management strategies. This course of therapy encourages insight and capacity to reflect on the meanings and functions of problematic behaviours and the development of alternative, healthier solutions.
