Duncan is an experienced psychosexual and relationship therapist who works with adult couples and individuals struggling in their relationships and sex lives, including difficulties with desire, intimacy, communication, and sexual difficulties.

Many people going through fertility treatment or loss find that intimacy begins to change, particularly when sex becomes associated with pressure, timing, disappointment, or grief. This can affect not only a couple’s sexual connection, but also how each person experiences their body, desire, and sense of self. Duncan offers a non-judgemental space in which couples and individuals can explore what is happening between them, understand the emotional meanings beneath the surface, and begin to make changes that feel both realistic and sustaining. Duncan is also interested in the effects of boarding school experiences on adult relationships.

Alongside private practice, Duncan has taught and supervised on the Couple Therapy for Depression training at Tavistock Relationships and continues to provide supervision for NHS Improving Access to Psychological Therapies staff. He has been a visiting psychosexual therapist and tutor at Tavistock Relationships, taught on the MA in Relationship Therapy for the Relate Institute, and taught on the MA in Counselling at Goldsmiths, University of London.

Duncan is  Chair of the UKCP College for Sexual and Relationship Psychotherapy (CSRP), and was previously the Director of Ethics and Standards for the Association for Counselling and Therapy Online (ACTO). He is also a member of the British Society for Sexual Medicine (BSSM), the European Society for Sexual Medicine (ESSM), the International Society for Sexual Medicine (ISSM). Duncan is registered with the Information Commissioner’s Office and has an Enhanced Certificate from the Disclosure and Barring Service.

Duncan holds an MSc in Psychosexual and Relationship Therapy and a Certificate in Psychosexual Studies from Tavistock Relationships, and an MA in Relationship Therapy from the Relate Institute.
