Really inpatient, if you are 5 minutes late and you will be rescheduled to 2 months’ later date. Worst service ever.

Highly recommend. From my son's first consultation a few years ago with Dr Southall to getting braces with Dr Clare and the continued care with Sharyn, the process has been easy, well explained, and made affordable for us. The whole team at GSO has been great to deal with.
Angelique Fourie
I would like to give a very BIG thank you to Dr Natasha Clare and the rest of the amazing staff. I highly recommend Greater Springfield Orthodontics, especially for adult braces. My braces were barely visible & just took 17 months to give me the smile I wanted! The whole process was seamless and very easy going, to my surprise. The Suresmile Technology was great! The kind reception staff were very flexible with my schedule & I was never afraid to ask questions and raise any queries. The whole team was just outstanding.Thank you! 5 stars.
