Isabel Clarke


Consultant Clinical Psychologist

Isabel has been working to move various mental health services within the NHS (acute, primary care etc.) in a more holistic direction for over 30 years, and group work has been integral to these initiatives. She did the introductory Group Analysis course in the 1990s. The approach she has developed (Comprehend, Cope and Connect) is a third wave CBT integration, but awareness of the underlying therapeutic factors underpins her approach to all groupwork. See her website (www.isabelclarke.org) for more information, including about her books and other publications.
