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 broad range of mental health difficulties. I believe in working collaboratively with clients to develop effective ways of dealing with difficult experiences or challenging situations that may cause distress. I use several evidence-based psychological therapies, which are 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 10 years experience of conducting research in the fields of child and adolescent mental health, parenting, and attachment. More recently, 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).

I currently hold 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.

I am a member of Hampshire and Surrey Psychology, which assures you that your call or email will be responded to; ideally the same day but certainly within 24 hours. If I am unavailable or my caseload is full, our practice manager will be able to advise you which of our therapists might also be suitable for you to talk to if you wish.

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.
