While Dr. Berdan was very nice, he did not immediately address the problem for which I originally went to him. Instead, he decided that I needed deep scaling (when they clean between your gums & teeth), which took approx. 4 sessions and required me to pay $125 out of pocket for each session. Then he started to treat me for my original problem, by which point, I was tired of going to him and abandoned my treatment plan. He seems competent, and again, very nice, but just be careful when agreeing to services that you don't necessarily need.
