Gill Green

BA (Hons) M Clin Psychol D Clin Psych C Psychol AFBPS
Chartered Clinical Psychologist

People say that I’m very easy to work with; I’m down to earth and practical (I call a spade a spade) but I’m also warm and supportive. I’ve been a clinical psychologist since qualifying in 1987. My roots are firmly in cognitive behavioural therapy (CBT); I trained in Oxford at the time when CBT was being developed and I was fortunate enough to be supervised by Aaron Beck, widely acknowledged as the founder of this approach. CBT has developed since that time and I regularly undertake training and supervision to broaden my skills.   I include approaches such as mindfulness and other elements of Acceptance and Commitment Therapy to help people with a wide range of difficulties, including anxiety, depression and relationship difficulties.

More about Gill...

As well as working with individual clients as a clinical psychologist, I also work with organisations worldwide, coaching and training business leaders and their teams to lead and perform better (thereby achieving their business objectives).I am passionate about health and wellbeing at work, and I am conducting research with several organisations, looking at how increased work pressure can lead to bullying, sickness and absence.

Following the 2016 German Wings tragedy, I am also developing training resources for a number of airlines, to increase awareness of mental health problems amongst pilots. As part of this I am involved in training pilots to offer peer support to their colleagues. I am a chartered clinical psychologist and Associate Fellow of the British Psychological society, and I am registered with the Health and Care Professions Council.
