My professional background is in social work (probation, and field, hospital, and psychiatric social work) and psychotherapy (voluntary sector youth counselling, and private pratice). I completed training in gestalt therapy and transactional analysis, in addition to which I have studied person-centred psychology extensively. With my partner, Louise Embleton Tudor, I founded the organisation, Temenos, in Sheffield, which was – and still is – committed to person-centred education and training, and which we directed for 17 years (1993–2010). We also designed and ran the first postgraduate person-centred psychotherapy & counselling training programme in the UK, which was also validated as a master’s degree – a Master of Science (by Middlesex University, London).

I am a Certified Transactional Analyst (Psychotherapy) and a Teaching and Supervising Transactional Analyst (Psychotherapy), a Teaching Member of the International Transactional Analysis Association, and an Associate Member of Waka Oranga.

I am the author of over 400 peer-reviewed publications, including 27 books.

As an acadmic supervisor, I have supervised seven doctoral candiates to completion, and 38 Master’s students to completion.

In 2020, I was the recipient, with Graeme Summers, of the 2020 Eric Berne Memorial Award, given by the International Transactional Analysis Association, for our work on co-creative transactional analysis, the citation for which reads ‘For Their Work on Cocreativity and Introducing a new Metaperspective for Thinking About Theoretical Development and Design in Transactional Analysis’.
