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.
