Dr. Sanford Bell

Greetings to you my friend!

I started practicing at Courtice Health Centre Dental in 2015. My focus is comprehensive and compassionate care that starts with the patient assessment. I promote preventive dentistry in team-oriented and educational fashion, where each patient and I feel free to express and discuss our mutual needs and concerns. Since treatment plans are objective to the patient’s needs, each one that we create is customized to that individual. This helps us arrive at a plan together. In as much, our relationship (patient and provider) is a two way road. This road allows us to work together -- ultimately bringing about the best results. 

Yours truly
Sanford Bell D.D.S.
