About Us
TIO International is a global network of Specialist Orthodontists dedicated to innovation and technology, with a focus on clear aligner treatments. Supported by over 25 digital marketers and growth coaches, we foster innovation and help orthodontists plan, adapt, and grow their practices using the latest marketing and clinical tools.

Our Story
TIO was built by an orthodontist for orthodontists. Over 15 years ago, our founder Dr Grant Duncan made a decision that would forever change the way he practised orthodontics. With the expansion of our programme across Australia, New Zealand, the UK & Ireland and North America, now you can make that change too.
‘After starting just 10 Invisalign® cases a year, I grew to 300 Invisalign® cases in 3 years, and I now treat more than 450 Invisalign® cases a year over 90 clinical days across Australia. Throughout Australia, the UK, Ireland, New Zealand and North America, all of our members are able to tell their friends and colleagues similar success stories to my own.’ - Dr Grant Duncan
