MEET THE TEAM

John Rebullida

Founder & Behaviour Support Practitioner

Meet John, a seasoned professional in the disability sector since 2014, specialising in ABA therapy for children and adolescents. He’s dabbled in various ABA approaches, from DTT to PRT and VB, and began his journey as a junior therapist at the Lizard Centre in Sydney. Now, as an independent therapist and the founder of The Sky’s The Limit, his mission is to train, connect, and support dedicated therapists partnering with families seeking behavior therapy services.

Driven by his passion for helping vulnerable children, John ventured into Child Protection with the NSW Department of Communities and Justice in 2018 and later joined a not-for-profit organisation in 2019, gaining valuable experience in Case Management in children in out-of-home care. It was a tough role but rewarding to be helping families in need, he aspired to expand his impact beyond just children, leading him to the NDIS Quality and Safeguards Commission in 2021, where he audited positive behavior support plans and restrictive practices.

Today, John is a lecturer teaching behavioral psychology at university and he also works part-time as a Behaviour Support Practitioner for a nation-wide NDIS-registered service provider. With a Bachelor of Psychology from Macquarie University in 2017 and a recent micro-credential from Monash University in Positive Behavior Support Practices, he is working towards becoming a Board-Certified Behaviour Analyst.

John doesn’t get much spare time so he enjoys spending quality time with his cat and family.
