What Sets Pieter’s Approach Apart

Pieter’s work in forensic settings is guided by both compassion and clarity. He recognises that behind every case is a human being with a story, challenges, and the potential for change. Where appropriate, Pieter integrates trauma-informed care and evidence-based modalities such as Schema Therapy and Dialectical Behaviour Therapy (DBT).  This all happens within the context of keeping our communities safe.
