Intensive Short-Term Dynamic Psychotherapy (ISTDP) is a brief-term, emotion focused therapy which aims to get to the root of emotional difficulties in as short a time-frame as possible to enable clients to overcome symptoms and reach their full potential.

ISTDP is an accelerated form of dynamic psychotherapy. It is an active approach which focuses on processing emotional blockages responsible for symptoms such as anxiety, depression and relationship difficulties.

This method of psychotherapy is practiced internationally and has an impressive evidence base. More than forty published research studies show this approach to be highly effective for a broad spectrum of patients, with benefits that continue and increase in long-term follow-up.

Neborsky, MD, and Professor Allan Abbass. Her approach is focused on the attachment-based model of ISTDP.

Dr Lewis has experience both in private practice and in the NHS and has a particular interest in working with clients with anxiety difficulties and treatment-resistant depression, as well as those diagnosed with physical health conditions such as auto-immune disorders, fibromyalgia and chronic pain.

Therapy Inquiries

I work with individuals with a wide range of emotional difficulties as well as those with physical health conditions including fibromyalgia, chronic pain and other rheumatological conditions.  I have particular expertise in the areas of anxiety, depression and trauma.

I also offer ‘block therapy’ for clients who are travelling from overseas or from some distance in the UK.

I offer a 15 minute initial phone consultation, for which there is no charge. In this initial contact, you can briefly outline what you would like help with. This will allow us to evaluate whether it would be appropriate to set up an initial assessment session.

The initial consultation is a longer session, lasting two hours. In this time I can get a thorough understanding of your areas of difficulty, and you can get a  clear idea of the way I work.

We can then decide whether to arrange a block of sessions and I can estimate the number of treatment hours required.

Please use the contact form to send an inquiry or email: sharonlewis@me.com


I offer training for clinicians (including psychotherapists, counsellors, psychologists, GPs and psychiatrists) in Intensive Short-Term Dynamic Psychotherapy.  Courses range from introductory level to a three year training in ISTDP and can also be offered in-house.
ISTDP training focuses on advanced psychotherapy techniques such as:

Monitoring unconscious signaling of anxiety in the body, and specific regulation techniques.

Identifying maladaptive defense patterns and providing the patient with the option to replace these with adaptive coping strategies.

Identifying and intensifying the somatic experience of emotions in the here and now.

Trainings take place in Oxford and Central London
and can also be arranged in-house.
