Behavioural Therapist

Sarah is a highly qualified Cognitive Behavioural Hypnotherapist and NLP practitioner. She uses a combination of counselling and hypnotherapy techniques to enable Clients to address the underlying blocks or causes that have led to their current physical and/or mental situation. Through this exploratory and understanding approach, Sarah is able to help Clients “unlock” their potential, to improve their self-confidence and to move forward with positivity; she works with Clients with a range of issues including weight control problems, loss of confidence, poor body image, dependencies and irrational fears. Her work, in combination with Laurent’s scientific approach to performance and nutrition, has led to outstanding results.

Sarah was a professional actress for many years and turned to hypnotherapy to help her with her confidence issues associated with this profession. Her own greatly improved quality of life achieved through hypnotherapy inspired her to help others. Sarah trained at the UK College of Hypnosis and Hypnotherapy in CBT Hypnotherapy and is trained in Neuro-Linguistic Programming. She has had a practice on Harley Street, London for some years.


“Seeing the genuine transformation in clients when they finally let go of their unwanted habits or behaviour which has kept them ‘stuck’ for years, and help move themselves forward in more supportive and helpful ways fills me with a sense of personal happiness and pride every time.”
