Dr. Knapp (and his team) is top notch. Dr. Knapp is an amazing dentist who I trust unconditionally. His passion for patient care is evident

I was really anxious about having a root canal & had many questions. His response was that I could take Valium. He also quickly suggested that I could have the tooth removed. Only after many questions he did a good job explaining the procedure to me. I know it was the end of his work day but he should feel ashamed of his obvious lack of caring. I felt like he was just waiting for me to hand over the cash. Will ask for different dentist in the future.

It all seemed very rushed - very unlike my experience at smaller dental offices. I was quickly passed off between 4 different people. The dentist seemed a little disheveled and only looked in my mouth for about a minute. I had the inkling that they were being complimentary of my teeth in order to keep me as a patient. I havent been to a dentist in 5 years (which they knew).

I used to like Dr. Knapp alot. Very Gentle and concerned. From this experience of appointments things have changed. You have to read all the comments to get a fuller picture. But he became very short, definately not as gentle as usual. The whole experience has become very uncomfortable and once I finish this work I need I will not be back. I have never been treated this poorly by people making so much money off of me. Worst service experience in my lifetime.
