Chartered Clinical Psychologist


About me

I am a Chartered Clinical Psychologist with over 10 years experience of clinical work with a variety of client groups presenting with a wide range of mental health difficulties, both in the private sector and in the NHS. Over the course of this work, I acquired extensive experience of several evidence-based psychological therapies scientifically proven to produce positive change in common mental health-related problems including difficulties with anxiety, depression, adjusting to traumatic/stressful events, low self-esteem, and relationship breakdown. I also have over 15 years experience of carrying out high quality research in the fields of child and adolescent mental health, parenting, and attachment. My research and clinical interests also include the understanding of mental health difficulties based on continuum views of experience (e.g. paranoid beliefs along a continuum of severity, from nonclinical to clinical levels).

Besides my private practice, I have until recently held a part-time NHS post as a Highly Specialist Clinical Psychologist in an inpatient rehabilitation service offering treatment to adults with complex and enduring mental health difficulties.

Registration and professional membership

I am registered as a Practitioner Psychologist with the Health & Care Professions Council (HCPC) and I am a Chartered member of the British Psychological Society (BPS).

Therapy approach

My approach to psychological therapy is integrative, tailoring the most effective treatments to each client’s specific difficulties or concerns. I also emphasise goals and change-based therapies, which require a trusting and collaborative working partnership both in and outside sessions. To develop this trusting and collaborative stance, I aim to provide clients with a safe space in which they can feel heard and understood in a non-judgmental and empathic way, support them to identify their strengths, and promote their capacity to learn healthy ways of coping with psychological difficulties or distressing situations and achieve personally meaningful goals.

The psychological therapies I most frequently use are: Cognitive Behavioural Therapy (CBT), Compassion-Focused Therapy (CFT), Schema Focused Therapy (SFT) and Mindfulness-Based Cognitive Therapy (MBCT). Other therapeutic models that I draw upon include Acceptance and Commitment Therapy (ACT) and Dialectical Behaviour Therapy (DBT).

Regardless of which therapeutic approach is used, my aim is to provide clients with an opportunity to safely explore difficult thoughts, emotions and behaviours; gain insight into usual patterns of thinking, feeling and behaving and their impact on one’s life.

Working collaboratively with clients, I also aim to help them develop more effective ways of managing or relieving difficulties which may be causing them significant psychological distress or getting in the way of leading a more fulfilling and balanced life.

Areas of clinical interest

In line with my specialist clinical experience and research background, my main interests include working with:

  • Complex mental health difficulties (e.g. psychosis; bipolar disorder)
  • Anxiety disorders (e.g. OCD, panic, phobias, health anxiety)
  • Low Mood / Depression
  • Post-traumatic Stress Disorder (PTSD) – including single or multiple trauma
  • Personality disorders
  • Relationship difficulties
  • Low self-esteem
  • Emotional regulation difficulties
  • Anger / Problem behaviours
