Thorne Dental Team


Dr Geoff Thorne

I graduated from the University of Queensland in 1983 after being awarded a scholarship from Queensland Health. After practicing in North Queensland and Tasmania I moved to Armidale with my wife Karen and two young children ten years later.

Armidale, with its excellent educational facilities, national parks, and supportive community has proved an excellent place to raise a family and, since we arrived, Karen and I have welcomed another two children to our family!

I enjoy all aspects of dentistry and am particularly interested in the role of interceptive (phased) orthodontic/ orthopaedics in developing a beautiful smile, and how dentistry can play a role in treating sleep apnoea.

I ensure that I keep up to date by enthusiastically continuing my education and have undertaken additional training to become experienced in comprehensive restorative work and implant dentistry.



Dr Peter Norton

I graduated from the University of Adelaide Dental School in 2004 with prizes in Dental Clinical Practice and Prosthodontics, and admission to the Dean’s List.

I joined Thorne Dental in 2005 and lived in Armidale for five years. I now live between Sydney and Armidale.

I believe in a no-nonsense approach to dental care. I have a particular interest in preventing dental problems for my patients through education and a range of preventive treatments. I also enjoy offering a range of services in cosmetic dentistry and restorative dentistry.

Dr Monica Lee


I previously lived in Singapore and South Korea before moving to Australia in 2010. I hold a Bachelor of Nursing as well as a Doctor of Dental Medicine, which I obtained from the University of Sydney in 2018. That year I also won the Royal Australasian College of Dental Surgeons (RACDS) Academic Prize for Research.

Following this, I worked as a dentist in Sydney and Newcastle prior to joining the team here in Armidale. My main focus is preventative care because it is about empowering the patients to be in control of their own oral health. I’m also interested in developing more surgical skills in the future.

I love being part of a supportive team that works cohesively to provide a positive experience for patients, especially those with dental anxiety.

Outside of the practice, I enjoy yoga, bushwalking, and catching up on Korean dramas and films.

Dr Johnson Ye

I was born and raised in Perth, and studied a Doctor of Dental Medicine at the University of Western Australia (UWA), graduating in 2020. At UWA, I was also the recipient of the John Prichard Memorial Prize for Dental Public Health. I moved to Armidale for a tree-change as I prefer the weather a bit cooler in summer. I believe in making the most of what I have been given for the greater good, so I’ve chosen to help people improve their oral health.

My areas of interest are:

  • Preventative dentistry – educating patients on small changes can greatly improve oral health and quality of life.
  • Minimally invasive dentistry – modern materials and approaches now mean treatments can be less destructive and more comfortable.
  • Keeping abreast of the latest dental technologies and upskilling – the modern world is in a state of flux and dentistry is no exception.

I enjoy being a dentist because it provides an unparalleled opportunity to engage with a broad cross-section of the community and help to improve the lives of patients.

I’m a self-confessed “history, politics and economics nerd”, a huge Formula One racing fan, I enjoy watching cricketer Steve Smith score runs, watching documentaries, and listening to indie rock. I’m a fluent in Mandarin Chinese and love to use metaphors!
