Dr Farmer is passionate about orthodontics and the difference it can make in the lives of his patients. He works long hours caring for his patients but also somehow seems to find the energy for a full-on life outside work.

Dr Farmer grew up in Charters Towers and graduated from UQ with first class honours in 1985. After a few years working as a dentist in Mount Isa, he returned to university to study orthodontics for a further three years. He has also been a clinical supervisor at UQ.

When Dr Farmer is not working, you might find him riding a dirt bike, playing touch football or tennis, relaxing with his wife and children, overseeing his farm or showing his support for the Reds or Broncos.

His idea of the perfect holiday is a walk on the wild side. His wilderness trekking has already taken him to the Kokoda trail and Mount Kilimanjaro – but he’s always looking for the next adventure. Work too takes him overseas, where he attends orthodontics conferences in order to stay up-to-date with the latest research and treatment.

Kent works at ethos orthodontics Upper Mt Gravatt, Browns Plains, and Algester branches.


Marcus is a self-confessed ‘dentistry nerd’. Ever since he had braces as a child in Brisbane he has been fascinated by the ‘gadgetry’ and now channels this passion into ensuring the best innovations in orthodontics reach his patients.

Marcus studied dentistry at the University of Queensland and it was there that he met Kent Farmer, the other founding orthodontist of ethos. Marcus graduated in 1985 with first class honours and spent six years working as a dentist in Melbourne and Brisbane before returning to UQ to do his master’s degree in orthodontics. Marcus has served as an external examiner for post-graduate students and is involved in numerous professional and school-based committees.

With a love of ‘the great outdoors’ you might find Marcus trekking, skiing, sailing, dirt biking or rounding up cattle on his family farm.

With his wife Christine, their three teenage sons and the cattle farm to look after as well, life is never a dull moment for Marcus. Fortunately, he wouldn’t have it any other way.


Dr Chang was a pharmacist before switching to dentistry, in search of a career that would allow her to get to know patients better and make a greater difference in their lives.

Early in her dental degree, Dr Chang developed an interest in cosmetic dentistry. She graduated from the University of Queensland with first class honours and was awarded the university medal for academic excellence.

Dr Chang migrated to Australia from Hong Kong over 20 years ago and is tri-lingual, speaking fluent Mandarin and Cantonese as well as English.

She chose to specialise in orthodontics because she enjoys working with young people and seeing the difference a smile can make for them. She likes nothing better than to see the photos from her patients’ graduations or formals where a beautiful new smile shines through.

In her spare time, Dr Chang enjoys shopping, more shopping, traveling, bush-walking and cooking meals with her husband.
