“I’ve discovered through my training and experience as a practitioner and as the Clinical Director of CPG that psychological interventions can truly transform people’s lives, sometimes in a relatively short amount of time.  And, in the case of mental health, this can produce better outcomes than medical treatment for some people.”

About Me
Research & Publications

I’m passionate about exploring how the research and application of psychology and behavioural science can make a real difference to our wellbeing, and even the future sustainability of this planet. Evidence-based psychological skills can promote strong mental health, performance, and psychological flexibility, helping us to cultivate what is best in ourselves and to live well and thrive. 

I’ve been privileged to work with people of all ages, from all walks of life, suffering with a vast range of mental health problems. Despite the challenges I’ve witnessed people facing, this experience has given me a fundamentally optimistic outlook: I believe that people can move forward and live meaningful lives, even in the face of extreme adversity.  

I want our clients at CPG to be aware of all the options available to them here. I think choice is key, as is direct and fast access to the very latest advancements in evidence-based psychological treatment, and the very best quality of psychological care.

Michael is CPG’s Managing Director, Lead Consultant Psychologist, and Clinical Director.
