Originally from the UK, and with a Welsh background, Steve has worked in the mental health field in New Zealand since 1998, initially in a residential setting with adult clients who had a range of complex mental health issues.

Since October 2021 Steve has been working solely in private practice, with clinics in Thames and Paeroa.

Trained initially in an eclectic model of psychotherapy, Steve seeks to first understand the individual client’s needs and concerns, so that an appropriate treatment approach can be identified. Over the years Steve has drawn on a wide range of modalities, including CBT, DBT,ACT, IDT, TA, and mindfulness approaches. He has a keen interest in the psychoanalytic field and associated literature, as a way to best understand how past experiences can often underpin current distress.

Steve has had experience working with depression, anxiety, physical and sexual trauma, and a wide range of other issues, as well as in the assessment and treatment of children and adolescents with complex presentations. Steve is qualified in the assessment of Autism Spectrum, and has an interest in this area.
