I went to Dr. Riordan for the very first time and he is amazing!!! I have had three attempts at a root canal by other dentists and was determined to have my tooth pulled. But Dr. Riordon was sure we could complete it and he did an amazing job! He even text me on Sunday to make sure I was ok. I am very afraid of dentists, but I have a lot of confidence in Dr. Riordan, he's amazing!
