The woman who cleaned by teeth on Monday, July 9th (don't remember her name), was very kind, gentle, and supportive. For so many years (before I came to your office), I received harsh reports on my teeth--and how I was managing them- to the point of dreading the visits. The kindness I have received over the years at your office has encouraged me to make changes in the way I take care of my teeth. It has also taken away the dread of coming.

As usal, I get the best care for my teeth here with Dr.'s Hume and Carpentier. In fact I drive for at least an hour to get here. They are proffessional and kind too. I am a bit phobic of dentists, but these two know how to help me relax. for instance I had a warmed neck pillow at my last visit. It really did help me relax for the teeth cleaning. Thanks Dr. Hume and Dr. Carpentier!

Lets face it, saying you enjoy going to the dentist is like saying you enjoy chewing on tinfoil. But honestly, I actually LIKE going here. The staff is friendly and professional, the facility is clean and inviting (which is saying something, remember this if a dentists office!). And most importantly for me, Dr. Carpentier completely takes the fear factor out of every visit. He communicates clearly and explains whats what without scaring the hell out of you. Love this place!
