Dr. Kostoryz has performed several root canals on me. My first one really hurt, but he was very concerned and did his best to make sure I was comfortable during the process. The others he did with no pain at all. One was through a new porcelain crown unfortunately, but he did a wonderful job of covering the crown with like material to make it "pretty".
I will definitely use him again....if I HAVE to..hehe.
