Antonio Mendoza-Diaz, PhD



University of Sydney Master of Psychology (Clinical, ongoing)

University of Sydney PhD (Clinical Child Psychology)

Tony is a provisional clinical psychologist currently completing a Master of Clinical Psychology at the University of Sydney. Tony has always believed in early intervention, knowing that childhood is a critical period for lifelong health. This motivated him to complete a doctorate (PhD) in clinical child psychology from the University of Sydney, where he trained under Professor Mark Dadds at the Child Behaviour Research Clinic, focusing on children with conduct problems and oppositional behaviour.

From there Tony moved on to other early intervention projects, working in developmental psychiatry for over 5 years, focusing on neurodevelopmental disorders like autism and working in close collaboration with a range of health services. Tony receives regular individual and group supervision from experienced clinical psychologists.
