Existential Psychotherapy

Making space for what it means to be human.

I offer existential psychotherapy in person (Brighton and Hove) and online (UK, Europe and internationally) to provide a thoughtful, non-judgemental space to explore what is happening in your life, deepen your understanding of yourself, and find new ways of approaching life's challenges.

Primarily I work with people who have experienced trauma (particularly neglect and sexual violence), dissociation, facing existential and life crises, and/or have complex family relationships.

Existential psychotherapy offers a relationship where you can explore these experiences at your own pace, and understand their impacts on your sense of yourself, others, and the world around you. Therapy is not about having all the answers. It is about exploring questions you have about your life, making sense of your experiences, and discovering ways of living with more meaning and purpose, and in ways that feel right for you.

Clinical supervision

I offer existential-phenomenological clinical supervision for counselling psychotherapists, psychotherapists and counsellors.

My practice focuses on supporting practitioners working predominantly with clients who have experiences of:

  • trauma and dissociation - particularly sexual violence, domestic violence, intimate partner violence, abuse and neglect.

  • relationships and psychosexual concerns - specifically around trauma-related impacts.

  • familial complexity.

  • existential and life crises.

  • neurodivergence - particularly autism, ADHD and complex presentations.

With colleagues I have also co-developed a specific approach to existential-phenomenological clinical supervision, which focuses on the incorporation of movement and somatic processes in psychotherapeutic practice and relationships.

He is best known for his work on existential approaches to interpersonal trauma, having published academic books, articles and papers in the field.

Additionally, he has written and taught on existential and critical phenomenological approaches to neurodivergence. He is also currently editing a collection focused on formulation, bringing together the wide variety of traditions within existential psychologies, psychotherapies, counselling, and therapies, which is due for publication in 2027 (SEA).

Existential movement practice and psychotherapy

All of our existence emerges from movement, and our moving bodies are the means by which we have a self, relate to others and experience the world around us.

Frequently we find ourselves grappling with questions, dilemmas and experiences that are indescribable and cannot be put into words. Existential movement psychotherapy starts with your non-verbal, felt-sense of your moving body.

I offer existential movement psychotherapy in person (Brighton and Hove), and primarily I work with people who have experienced trauma (particularly neglect and sexual violence), dissociation, facing existential and life crises, and/or have complex family relationships.

Existential movement psychotherapy offers a relationship where you can explore these experiences through a greater sense of your body-in-movement, and through our movement dialogues. There is no right or wrong way to move. You don’t need to be a dancer or have any previous experience in movement to do existential movement therapy. The work begins wherever you are, with curiosity, openness and respect for your own pace.

In addition to existential movement psychotherapy, I have developed a range of existential movement practices and have delivered PlayFight workshops, which more specifically explore the relationships between play, assertion and aggression, including the thresholds and boundaries within these.
