About Us

We are completely committed to helping you and your family benefit from beautifully straight teeth…

At AAA orthodontics in Albany Creek and Strathpine our mission is to treat you as we would want to be treated — with courtesy, with the latest technology and techniques and with full explanations of what is happening and why.

We know you have better ways to spend your time than sitting in our waiting room. Dr McMahon puts effort and takes pride in being on time for appointments. You want the best results from your treatment and so do we.

We strongly believe all of our patients deserve a smile they can wear proudly. At AAA Orthodontics in Albany Creek and Strathpine we will go through your treatment plan step-by-step with you and encourage any questions or concerns so we can achieve the best possible result for you or your family. It is never too late to straighten your smile and at AAA Orthodontics we also offer adult treatments to help you get the smile you deserve!
