Dr. Knapp took his time figuring out what he wanted to do. I felt he really cared about my tooth problem and wanted to solve it so it would not happen again.

I marked I had discomfort because I had two fillings done. Dr. Knaap & his assist were great in easing the work being done. Am grateful they had time to fill them as I was scheduled for a routine cleaning & exam. Wonderful service!!

Dr. Knapp always does a great job. I know he is a busy man, so sometimes we have to wait for him or it seems like he is rushed to see everyone. This last visit though, we had a good amount of time with him.

Used a very condescending tone. Made me feel bad for having poor teeth health.

a filling he had done needed re-doing. they did it that day, which was appreciated. But it was done quickly and carelessly. He didnt even smooth it out between teeth after, so now, when I floss it shreds the floss. Id rather he not done it if he was going to do it so rushed.

for having seen a new dentist it was obvious that his qualifications in communication, sincerity, and client centered treatment was achieved .
