Unfortunately, I have had 4 root canals. Fortunately, Dr. Peterson has done all of them. He is completely professional, but is also warm and friendly and has a great bed-side manner. He is very gentle- I actually dozed off during one of my root canals! The procedures have all been a complete success with little or no pain following. Dr. Peterson's staff is awesome, from the front desk to the assistants. They could not be nicer or more accomodating. I can't say enough positive things about Dr. Peterson and his group. I highly recommend them!
