I had been coming here since I was young and had Dr. Hawryluk. I’ve now seen Dr. Steve Mastropole, and would give him a 10/10 for being an amazing dentist. My experience with him has been so great he is the only dentist I would like to see. He is very patient, kind, and considerate. He talked me through my whole procedure and made me feel very comfortable for something I was nervous about. Absolutely perfect service, I could not recommend enough!
