Meet The Team

Dr John CoolicanOrthodontists
Having been born in Sydney, John grew up in Bourke. For his high school studies, John attended St Ignatius College, Riverview as a boarder where his love of sport was developed and nourished.
After gaining his Bachelor of Dental Surgery at the University of Sydney in 1979, John worked in general practice in Gladesville, Ashfield and then Wollongong. In his spare time, he played Rugby for Australia and toured Argentina, New Zealand, France and Fiji with the Wallabies.
In 1985 he went to New Zealand for postgraduate studies in orthodontics at the University of Otago and gained his Master of Dental Surgery in 1987. The following year John joined Dick Abbott in practice at Chatswood and when Dick retired in 2002, John took over the practice. In 1989 he became a Fellow of the Royal Australasian College of Dental Surgeons.
John has been a Clinical Tutor (postgraduate orthodontics students) at Westmead Hospital and was on the Executive Committee which organised the 7th International Orthodontic Congress in Sydney in 2010. For relaxation John plays golf and runs half and full marathons to burn off surplus energy. Kayaking and mountain bike riding also helps keep the fitness levels up.
John and his wife Colleen live in Pymble and have four children. He still manages to be involved with rugby and is President of the NSW Rugby Union
