Greetings to you my friend!

I started at this practice in 2014, and practice concurrently in Courtice (Courtice Health Centre)
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.
