Dr Bryan Liew


Dr Liew (Khai Yi) graduated with upper honours and earned a Bachelor of Dental Science from the University of Queensland. He is a proud member of the Australian Dental Association.

As a teenager, Dr Liew wore braces, which sparked his interest in dentistry. He began to observe nice smiles and wanted to one day help his own patients reach their smile goals.

Today, he is particularly interested in endodontics (root canal treatment), porcelain aesthetic restorations and biomimetic dentistry, which focuses on restoring teeth to a natural-like strength and function. Dr Liew is also active in professional courses to increase his expertise to better serve his patients’ needs. It always makes his day when patients can regain confidence in their smiles or recover from any discomfort their toothache caused.  

Outside of work, Dr Liew loves playing games, making music, and experimenting with specialty coffee at home. He is from Malaysia, where he learned to speak multiple languages, including English, Mandarin, Cantonese and Malay.

Today, Dr Kumar loves being a dentist—the perfect combination of health and artistry—and is committed to providing the highest standard of care to her patients. She also works in partnership with her patients, offering advice for at-home oral hygiene routines. She is known for her gentle technique and skill.
