Found this site when searching on-line for someone in the Markham area to advise me on a replacement upper denture. I'm a senior who's had a full upper denture for over 50 years. Came across Sam's web site with positive reviews, so made an appointment. I was not disappointed. Very down-to-earth, informal approach, good advice and service. He's not happy until you are. I'm very happy with my new appliance and gladly recommend him.
