Dr. Cameron ChiangDentist
Hello! And welcome to my bio.

I grew up in Richmond Hill, majored in Neuroscience during undergraduate school, worked at Sick Kids doing research to help newborns with peripheral nerve injuries (brachial plexus) and then completed my Doctor of Dental Surgery training from the University of Toronto Faculty of Dentistry.

I believe in providing the highest standards of oral health care to my patients in a gentle and happy environment. I have always been a caring person and went into healthcare to make a positive difference in people’s lives.

I enjoy doing all facets of dentistry and I will always make sure that you are well-informed, well taken care of and satisfied with your oral health – my primary concern is the patient’s well being! By day I am a practicing dentist, but I also enjoy tennis, chess, movies and books – especially biographies.

Looking forward to seeing you in the chair!
