Post Doctoral Certification in Orthodontics - Oregon Health Sciences University
Specialist Clinical Associate (Syd Univ)

'Dr Marshall provides each patient with personal care and concern for patients individual needs.'

Dr Marshall's aim is to create for each patient the best possible facial aesthetics, function and smile. Treating both the face and teeth according to the patient's needs. We call this "working with mother nature" or interceptive care.

Ken likes to assess children at nine years when he can see the 'blueprint' for further facial development, planning their treatment options early. This may often mean that the patient's orthodontic treatment won't require tooth extractions.

Dr Marshall has practised as a Specialist Orthodontist for over twenty years and as a result enjoys extensive clinical experience.

After attending North Sydney Boys High School, he completed a Bachelor of Dental Surgery degree at Sydney University with a Commonwealth Scholarship. He then practised as a dentist in North Sydney for some years before completing a Masters degree in Orthodontics at Sydney University, which requires both intensive clinical studies and research.

His special interest in facial growth led him to complete a further specialist degree in orthodontics at the Oregon Health Sciences University (Portland, USA). This faculty is an integrated medical, dental and nursing school with an outstanding international reputation for clinical excellence.

Dr Marshall teaches in the graduate orthodontic department at Sydney University and has received several prestigious clinical awards from his professional peer group.

Recently Dr Marshall's focus has been on developing Invisalign® clinical protocols. The new era of digital- based NO BRACES orthodontics. Dr Marshall is a Platinum Provider of Invisalign® and actively involved in mentoring fellow Orthodontists.

Dr Marshall supports our local community by sponsoring art and Performing Arts Awards in our local schools. He has a healthy ethos, which reflects in his hobbies that span soccer, yoga, mountain biking and anything aquatic. He also enjoys a fine meal in an excellent restaurant.

Dr Piller and Dr Marshall are both experienced Specialists in Orthodontics.
