Wifey and I have been using Dorrow for several years and have no complaints. I've experienced cleanings, fillings, and fixing a chipped molar and everything has been great. Once I had dental hygienist that may have been considered a bit over-zealous, but man were my teeth clean.
Wifey had some straightening
Invisalign-type stuff done as well. She visited a few dentists in CH before and the cost difference for this was
significant.
FWIW, my mother works for a dentist who I still go visit when I'm home. He made a comment that the filling work I had done at Dorrow was good.
Based on our experiences, I can recommend Dorrow.
