I live in phoenix and had to have a root canal. Finding a good Dr in the area was a challenge as an endodontist is so specialized. My root canal was pain free and I felt very comfortable with Dr Doyon who did my procedure. I got a thorough education on what he was going to do and it put me at ease. I also heard about some of the horror stories about what can happen if it is not done right. Yikes! I was so thankful to find, in my opinion one of the most skilled. I hope you don't need one, but if you do this Phoenix endodontist I did feel comfortable giving a good review for, and that says a lot
