About me
I am a UKCP-registered integrative existential psychotherapist with over 20 years’ experience providing psychotherapy and counselling to adults in private practice, the NHS, and university settings. I also offer clinical supervision to both trainee and experienced practitioners. My approach is engaging, compassionate, and grounded in creating a safe, confidential space where we can explore and make sense of the challenges you’re facing. Depending on your needs, our work may be focused and goal-oriented—addressing specific issues—or open-ended and exploratory, allowing us to uncover the deeper meanings and patterns that shape your life. My Therapeutic Approach As an integrative therapist, I draw on a range of complementary modalities to tailor therapy to each person’s unique situation. My primary orientations include: Existential Psychotherapy This approach helps you explore life’s deeper questions—such as meaning, freedom, responsibility, and authenticity. Together, we’ll look at how you create meaning and relate to yourself, others, and the world around you. This process can support you in meeting life’s challenges with greater awareness and purpose, helping you live in a way that feels more authentic and fulfilling. Dialectical Behaviour Therapy (DBT) DBT is an evidence-based approach that supports emotional regulation, relationship health, and practical coping skills. Our work will balance acceptance and change—learning to accept yourself as you are while moving toward the life you want to live. DBT integrates mindfulness, emotion regulation, distress tolerance, and interpersonal effectiveness skills, and is particularly helpful for emotional dysregulation, BPD/EUPD, eating disorders, and complex trauma. Cognitive Behavioural Therapy (CBT) CBT is a structured, practical approach that helps you understand how thoughts, emotions, and behaviours influence one another. Together, we’ll identify unhelpful patterns and develop new ways of thinking and responding that align with your values and goals. CBT focuses on building concrete skills to reduce distress and enhance wellbeing. Psychodynamic Psychotherapy By integrating psychodynamic perspectives, we can explore how past experiences and unconscious processes shape your relationships, emotions, and patterns of behaviour. Bringing these dynamics into awareness fosters greater self-understanding, freedom, and fulfilment in life and relationships. Compassion and Mindfulness-Based Therapy This approach encourages a kinder, more accepting relationship with yourself and your experiences. We will explore how mindfulness—cultivating presence and awareness—and compassion—responding to suffering with understanding—can support healing and emotional balance. These principles underpin all my work, fostering resilience, clarity, and warmth toward yourself and others. Areas of Specialism I have a lot of experience with a broad range of issues, and some of these that work well with my integrative stance are: Depression Anxiety Relationship difficulties Self esteem and identity issues Anxiety disorders (including OCD and phobias) BPD/EUPD Complex trauma Additional Services Clinical Supervision I provide supervision to trainee and qualified counsellors, psychotherapists, and counselling/clinical psychologists. Research Supervision As a teaching consultant and research supervisor at the Existential Academy in London, I offer research supervision for students undertaking Master’s and Doctoral studies with qualitative methodologies. Spiritual Development For those interested in spiritual growth, I offer guidance—either integrated within psychotherapy or as a separate process. This may include support for those following a particular tradition or pursuing a personal path, as well as meditation reviews for those wishing to deepen their practice.
