My experiance with Dr. Cornatzer and his staff was excellent. Everyone I met, or spoke with on the phone was pleasant and personable. All communication was clear. Dr. Cornatzer performed several examinations. He explained what they were, and what they revealed. He also explained the path forward. I am grateful for his expertise, attention and care. Thank you !

I have been a patient of Dr. Cornatzer for 10 years and while I have always considered him an excellent dentist with an office staff that is a pleasure to deal with (treatment coordinator Bonnie Bolinski could not be more helpful or pleasant to talk to!) I am absolutely thrilled with the job he has done giving me a new smile! I really could not be happier with it and wanted to make sure I took the time to say so! I really could not have imagined how far my expectations would be to exceeded when this process started. THANK YOU DR CORNATZER! If you are looking for a good dentist there are probably a lot of them but if you want a GREAT one - call Dr. Cornatzer. :)

The staff is always friendly and puts the kids at ease, plus they really care about helping the kids understand what they need to do to keep their teeth healthy. I also really appreciate that they don't try to push unnecessary procedures. We're treated more like family/friends rather than just a patient.

Highly recommend!
