Far more than orthodontics, he is renowned for providing insights into airway issues in all age groups. This enables his approach to orthodontics to be holistic in nature, and results in changes to quality of life that far exceed traditional orthodontic approaches. He is highly sought-after as an educator, and bases his lectures on the positive impact this combined treatment approach can achieve. He is also passionate about sharing the benefits his philosophy provides from a practice-management point of view.  



Dr Mahony’s education in the field of orthodontics is extensive. He completed his Dental Degree at the University of Sydney before undertaking his Masters Degree in Orthodontics at the Eastman Dental Hospital, Institute of Dental Surgery, in London. He then went on to complete a Diploma in Orthodontics at the Royal College of Surgeons in Edinburgh.

He passed the post-graduation examination in the field of orthodontics at the Royal College of Dentists in Canada. He also attained a postgraduate qualification in Dentofacial Orthopaedics from the Royal College of Physicians and Surgeons in Glasgow.

He has a Membership in Orthodontics qualification from the Royal College of Surgeons in England.



Dr Mahony is based in Sydney, where he teaches in state-of-the-art learning facilities that provide superior environments for both theoretical and practical training. He is a talented presenter with the inherent ability to present information clearly, succinctly and in a way that inspires and resonates with his audiences.
