He’s had more than 20 scientific articles published in international dental and orthodontic journals, and before coming to us spent 10 years as a senior lecturer in orthodontics at Otago University overseeing and supervising exceptionally complex orthodontic cases.

He’s also acted as an examiner in orthodontics for Australian universities.

In his downtime Andrew is family-focused and a keen traveller and cyclist. You’ll often find him tackling our scenic cycling tracks through bush and across adventurous terrain. He’s also an extremely talented handy man and created custom-made items for our clinic. Originating from Zimbabwe, he also has a great interest in African wild life.

Outside of orthodontics, Catherine looks forward to weekend travels in a 1960’s caravan, renovated by her husband, with their dog, Agnes.  She is also enjoying trying out the new cafes and restaurants that have popped up since she last called Hamilton home.

After graduating with a BDS from the University of Otago, Mark began his career at Waikato Hospital as a maxillofacial house surgeon. He spent two years in New Zealand and London in general dental practice before moving to Rochester, New York, where he qualified as an orthodontist at the Eastman Dental Center.

He then joined the cranial facial department of the Hospital for Sick Children in Toronto, Canada, as a clinical research fellow. He spent two years there before returning to Hamilton in 1988 to open his own practice and raise his family.

Mark is a published expert on the treatment of cleft palate in children, and is the consulting orthodontist for Waikato Hospital’s cleft palate team.

Outside orthodontics, Mark’s overflowing garage is a testament to his love of sport. If he’s not mountain biking, he’s playing golf or fishing. Mark lives with his wife and previously his 3 children on what he calls his ‘life sentence block’ on the outskirts of Hamilton.
