I just guessed at the number of years I've been seeing Dr Garhardt, but it's been at least ten. His friendly, professional staff makes me comfortable every time I go in for a cleaning. I just recently had a filling done, and I never felt even a prick from the shot, and unless I point it out, you would have a hard time finding the tooth that was filled. Everyone in my family feels the same way. A return customer for over ten years should tell you enough.
