About

Bio

I’m fluent in English and Mandarin and enjoy the ability to help patients who might not otherwise have access to care — whether they need help outside of standard working hours, are in a remote location, or are without insurance. I like to get to know my patients through multiple visits, to monitor chronic conditions closely, practice disease prevention, and help encourage and maintain healthy lifestyle habits. I truly believe a strong doctor-patient relationship is the key to positive treatment outcomes, and am grateful for technology that allows patients to schedule visits easily with a doctor they trust. In addition to being a family doctor, I’m a father to two young daughters. When I can, I like to keep up with the Toronto Blue Jays and Vancouver Canucks.

Specialties
