Our Orthodontic practice was established in approximately 1975 by Dr. Graeme O’Neil, originally located at 34 MacMahon Street. The practice was then taken over by Dr. Bill Choo in 1980. Dr. Kon joined Dr. Choo in 1998 and eventually took over the surgery following Dr. Choo’s retirement. We relocated in January 2004 to our current residence at 33 MacMahon Street.
Over the years, we have expanded our business to accommodate our patients’ needs. As such, we now have three associates (Dr. Chai Jankulprasut, Dr. Daniel Tan and Dr. Tiffany Huang) working with Dr. Luke Kon to assist in providing flexibility along with exceptional care to our patients.
In our surgery, each orthodontist cares for their specific patients. Orthodontic treatment will be carried out by this Orthodontist and certain procedures by our specially trained Hygienists. All treatment is under the supervision of the Orthodontist and is held to the highest standard of excellence. Periodically, should you require an appointment outside of your Orthodontist’s scheduled clinical hours, one of our other Orthodontists would be happy to provide assistance.




Dr. Huang is an enthusiastic and dedicated orthodontist who aspires to provide the best orthodontic care and creating beautiful smiles. She speaks Mandarin, Hokkien and English.
