Leo is a Clinical Psychologist working for Devon Partnership NHS Trust in Neuropsychology and Adult Mental Health Services. He developed an interest in ISTDP whilst looking for an approach that had powerful change mechanisms capable of accelerating the process of therapy and leading to profound improvements in wellbeing. His work draws on attachment theory and affective neuroscience as a framework for understanding causes of mental health difficulties and ISTDP neatly fits into both these frameworks.

Leo has a special interest in medically unexplained symptoms (MUS) and he has presented on this topic at various conferences and as part of the ISTDP-UK London Seminar Series. He has been fortunate to be involved in research on a wide range of topics including ISTDP, MUS, non-epileptic attack disorder, eating disorders, bipolar disorder, men’s mental health, and positive psychology.
