Dr. Quigley is the best dentist I have seen in my entire 67 years of gnashing and gnawing and otherwise abusing my teeth. He has taught me about proper brushing technique, grinding and surface wear, periodontal disease, the importance of flossing, and how to minimize dental caries. Recently, he has even diagnosed a small growth on the gums which needed to be excised and biopsied in order to rule out the presence of pre-cancerous cells. (This was not detected by my ENT doc, so I am very lucky to be a patient of Dr. Quigley.) A+++ Recommendation!
