The staff at Dr. Whitner's office were all very friendly. I had a root canal done, and he seemed to do a good job. However, he didn't explain the procedure very well when I asked him. He's not one to volunteer much information about what is going to happen and how it went. I went to him because he's the only endodontist who took my insurance in a 30 mile radius. I would go to him again if I needed another root canal.
