Meet Our Team

Home » About Ethos » Meet Our Team

We want you to feel welcome whenever you walk in the door at ethos. So expect a warm smile, a friendly greeting and ongoing support.

Your smile starts now

At ethos, we genuinely care about our patients’ comfort and well-being, and we want you to have a great experience. All our orthodontists and support staff are passionate about the possibilities that good orthodontic treatment can create.

Our founding orthodontists, Marcus Tod and Kent Farmer, have more than 50 years experience between them, so as well as being technical experts, they know a thing or two about patient care.

Marcus and Kent make it a priority to create an enjoyable, dynamic environment for patients and staff alike. Of course, they take their work seriously, and hand-pick only the best orthodontists to work at ethos – and work on your smile!

Dr Kent Farmer

BDSC MDSC(QLD) MRACDS

Kent 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.

Kent 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 Kent is not at ethos, 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.

Kent’s 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 our Upper Mt Gravatt and Browns Plains branches.

Dr Marcus Tod

BDSC MDSC(QLD) FRACDS FADI

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.

Marcus works at our Upper Mt Gravatt and Clayfield branches.

Shari graduated with first class honours in Dental Science from the University of Queensland in 1990. She worked in a busy private dental practice in Brisbane for a number of years before deciding to return to postgraduate study to specialise in orthodontics.

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