Dr Ethan Zappala

Ethan was born and bred in North Queensland. For Ethan the choice to study and pursue a career in dentistry came when undertaking observational placement during high school. During this time Ethan grew to appreciate all aspects of the profession. The mastery involved within the profession drew Ethan’s attention the most, never being one to shy away from a challenge he became determined to achieve clinical excellence himself.

Following high school Ethan went straight on to study a Bachelor of Dental Surgery at James Cook University in Cairns. Studying through a rural university allowed Ethan to learn much more about the health system and issues faced within rural communities...

During university Ethan provided dental services throughout North Queensland at both public and private dental clinics. Following university Ethan stayed in Cairns at a private dental practice offering a full complement of general dental services. It was shortly after university that Ethan became very fond of restorative dentistry and saving teeth. His pursuit of clinical excellence means that he never settles for second best and strives to ensure all patients receive personalised treatment

Ethan moved to the Sunshine Coast in early 2019 to continue developing his skills within private practice and all aspects of general dentistry. Ethan has since broadened his knowledge and honed his clinical skills to ensure he continues to provide the best dental experience possible by completing a Post Graduate Diploma of Aesthetic and Restorative Dentistry. These studies allowed Ethan to further enhance his skills in dental fillings, crowns, veneers and smile make-overs. Ethan endeavours to bring his enhanced knowledge and skillset to all his patients providing the highest quality results. Keeping in line with his love for saving teeth Ethan enjoys performing Root Canal Treatment and greatly enjoys its complexity.

Outside of work Ethan enjoys staying active, he is enjoys most outdoor activities and is an avid fisherman. Originally being sceptical about moving so far from home and family, Ethan has fallen in love with the Sunshine Coast and everything it has to offer. Ethan plays in several local social sports competitions to stay active whilst getting to know the community around him. When not in the office or on a court or field, tinkering around the house with DIY projects takes up the remainder of Ethan’s time.
