Meet Russ Harris: Physician & Psychotherapist

Dr Russ Harris, MBBS, is an internationally-renowned ACT trainer, and author of the world’s best-selling book on the topic, The Happiness Trap. Russ’s background is in medicine. As a physician, he became increasingly interested in the psychological aspects of health and wellbeing, which ultimately led him to change careers, and become a therapist.

In the last two decades, Russ has trained over 90,000 health professionals in ACT. He has authored four textbooks (including ACT Made Simple and Trauma Focused ACT)  and six self-help books (including The Reality Slap and ACT with Love). His best-known book, The Happiness Trap, has sold over one million copies worldwide, with translations into 30 languages.  (To download the opening chapter, click here.)

In 2015 Russ created an ACT protocol for the World Health Organisation, for use in refugee camps. The WHO have  published three RCTs based on this protocol, showing that it not only significantly reduces depression and PTSD, but also prevents the onset of mental health disorders in those at high risk.

Russ has a unique model for training, which makes ACT concepts simple, accessible, and easy to implement. His textbook, ACT Made Simple, is the top-selling ACT textbook in the world.
