Dr Kosy grew up in Wollongong and moved to Sydney to complete his Bachelor of Dental Surgery degree. After working in the Illawarra, he moved to Newcastle where he practiced dentistry for thirteen years. His keen interest in orthodontics led him to undertaking a Diploma in Clinical Dentistry majoring in Orthodontics, Implants and Advanced Restorative Dentistry which led to an invitation from the University of Adelaide to join the three-year Doctorate in Clinical Dentistry in Orthodontics programme. This provided him with excellent training and experience with the best new methods and materials in the treatment of juvenile, adolescent, and adult orthodontic concerns. In parallel, he completed special needs orthodontics courses, including the treatment of temporal mandibular joint dysfunction, obstructive sleep apnoea and cleft lip and palate. While working as a senior registrar at Adelaide Dental Hospital in the last year of the programme, he was seconded to the world renowned craniofacial unit at the Adelaide Women’s and Children’s Hospital and the cleft lip and palate unit at Flinders University. In the same year, he travelled overseas to become one of the first post-graduate orthodontic students in Australia to successfully sit the examinations for Diploma Membership of Orthodontics of The Royal College of Surgeons of Edinburgh. He returned to the city he loved and set up home in Newcastle. He renamed his practice ABC Orthodontics with the aspiration to offer the Hunter community the very best in orthodontic treatment. To support that, he regularly attends local and international continuing education seminars and conferences, so he can continue to provide patients with the latest proven orthodontic technology and techniques. Dr Kosy has been made a Member of the Faculty of Examiners in Orthodontics for the Royal College of Surgeons in Edinburgh and also recently became the consulting orthodontist for the Maxillo-facial Surgery Department at John Hunter Hospital.
