Always the best doctor visit. Setting up the appt. was unusually bad though. 1st) someone told my sister it had been a year and a half since my last visit and asked her to give me a hard time. It was a little more than six months, because of the scheduling problems I am about to outline. But also, my business is not to be shared if it is negative. 2) I called many times to make an appt., but had trouble finding a good time for one. Finally, I left a voicemail on the doctor line and someone left me a message regarding two times. I called to confirm one of them and not only did they not know what I was talking about, the woman said there were no available apps., even though I had just been called. She must have been new because she didn't know me and was actually rude - which is not the Kreitzberg way.

I LOVE DR. K!!!!!!

I cracked a tooth over the weekend. I was in first thing Monday morning and he was able to put a crown on the tooth. I was on my way within an hour!

Everyone is always so friendly. I had my teeth cleaning first with MaryEllen then my fillings with Dr. Kreitzberg. MaryEllen is very gentle and makes the cleaning less stressful. Dr. Kreitzberg is always singing happy tunes and does great work. I had 2 fillings done at once and the novocain is always the worst part. But I didn't feel anything when he gave me the shot. I highly recommend a visit and everyone will make you feel comfortable.
