Clinical Experience

I completed my doctorate in Counselling and Psychotherapeutic Psychology in 2003. The training consisted of three components: academic, research and supervised practice within the NHS and in Student Services. This led to Chartered Counselling Psychologist status with the British Psychological Society.

Counselling Psychologists are trained to use a variety of therapeutic methods so as to be able to adapt the therapy to the particular needs of the individual. I trained to use Cognitive Behavioural Therapy (CBT), Dialectical Behaviour Therapy (DBT), Psychodynamic and Humanistic/Person centred therapies. I have a particular interest in the use of Positive Psychology in therapy as overcoming difficulties is only part of the journey to becoming happier. I am a member of the International Positive Psychology Association (IPPA).

I have particular experience of diagnosis and treatment of Borderline Personality Disorder and of high risk individuals presenting with self harm/parasuicide, self-destructive behaviours, addictions and other multi-impulsive and risky behaviours.

I have been in private practice since 2006 and I assess, treat (and write reports when necessary!) a broad range of mental health problems with adults, teenagers and children. I have considerable experience with treating depression, anxiety disorders (including general anxiety, panic disorder, health anxiety and OCD), Post Traumatic Stress Disorder, addictions, eating disorders, adjustment disorders, anger and stress management. I also work with teenager and young adult difficulties, deliberate self-harm and extreme emotions.

From 2002-6 I worked as a Senior Clinical Psychologist at tertiary level in the NHS within a specialist psychology service within Surrey and Borders NHS Trust). This service comprised forensic psychology, personality disorder and learning disabilities services and a specialist Dialectical Behaviour Therapy Programme. I gained experience with a broad range of severe and enduring mental health problems: psychosis, personality disorders, chronic and severe anxiety and depression as well as those who experience extreme emotions, self-harm, self-destructive behaviours and parasuicide/suicidal behaviours.

I have also worked in student counselling services, general adult psychotherapy, Asperger clinic and learning disabilities services.

Before returning to clinical practice I founded a market research consultancy. Research Works Ltd (now based in St Albans, Herts). As a researcher I specialised in qualitative research (eg focus groups, in depth one to one interviews) for Government public health campaigns in various areas including addictions (smoking, drugs, alcohol), Sexually Transmitted Diseases (including AIDS), and skin cancer (sun awareness) as well as brand and product development programmes.
