I just had my 4th root canal done by Dr. Doering. Every time I go there , the staff is always friendly and willing to answer any questions I may have. Dr. Doering is very kind, patient and answers all of questions completely. He talks me through every step of the procedure. I have never had any pain during any of the root canals done by Dr. Doering. I would never go anywhere else to have a root canal done. I would recommend Dr. Doering to anyone!
