Darin is well known for his work with children, adolescents and adults with Autism Spectrum Disorders. Darin has set up award winning early intervention services in Western Australia for children with Autism Spectrum Disorders and related conditions. He was initially trained in Applied Behaviour Analysis (ABA), Clinical Behaviour Analysis and Functional Analytic Psychotherapy. After many years working with developmental specialists and clinicians his frustration at not being able to bridge the gap from ABA to complex behavioural and emotional domains lead him to Relational Frame Theory (RFT). He has since applied Relational Frame Theory (RFT) to hundreds of developmental programs for children with Autism Spectrum Disorders and special needs and continues to practice clinically using therapies developed from RFT such as Acceptance and Commitment Therapy (ACT) and other third wave Cognitive Behavioural Approaches.

Darin has lectured at the tertiary level and has provided over 150 training courses to a wide range of populations in the medical, health and public settings.  He is a sought after speaker in the use of evidence based practice to promote psychological wellbeing and development around the world having been invited to speak in the UK, Europe, the US and most of Australia.
