Born and raised in Sydney’s inner suburbs, Dr John completed his primary and secondary schooling locally before commencing tertiary studies at the University of New South Wales in 2001. He graduated with a Bachelor of Commerce in 2004 before pursuing dentistry at the University of Sydney, where he graduated with Honours in 2008.

During his dental training, Dr John developed a strong interest in orthodontics and undertook research in the field. He authored a thesis examining sleep apnoea and the effects of mandibular orthopaedic functional appliances on posterior airway space, which was later published in the Australian Orthodontic Journal.

After graduating in dentistry, Dr John gained broad clinical experience over six years working as a general dentist across rural New South Wales, including Dubbo and the Southern Highlands, as well as Sydney’s western and south-western suburbs. This period provided him with a strong foundation in comprehensive patient care.

In 2014, Dr John was accepted into the highly competitive University of Sydney Orthodontic Program, where he completed his specialist training and graduated with a Doctor of Clinical Dentistry in Orthodontics. During his specialist studies, he conducted clinical research into accelerated orthodontics and root resorption, which was subsequently published in the European Orthodontic Journal.
