Tim Acton is a Clinical Psychologist with over 40 years’ experience in assessing and treating trauma-related disorders in both NHS and private settings. Tim has maintained a long-standing interest in Personal Construct Psychology (PCP) since his undergraduate work on the Sociality Corollary. Trained in Cognitive Therapy, he can see how PCP and cognitive approaches help clients make sense of trauma, “challenge” invalidating personal constructs, and reconstruct safer, more coherent worldviews.

Sherin Jackson worked as a Clinical Psychologist AFBPsS and PCP psychotherapist UKCP for twenty years in the NHS. She later completed a PhD “Self/Other Construing in Children and Adolescents” using the PCP approach and continued to work for a further twenty years using PCP techniques to assess children and families in difficulty for the Court.

She is committed to PCP, finding it useful over the years as well as currently, and is delighted to see the links between the Quakers and Kelly’s approach to life.
