My appointment was for a root canal but after examining the tooth Dr Withrow, pointed out some problems that could happen that could not be determined until he began the procedure. He took a lot of time to discuss it with me and we felt the best procedure would be to extract the tooth. He then took the time to find an available oral surgen in the area. He found one that was available to do the extraction immediately. This was a big help as I was visiting from out of town and needed treatment at that time.

One of the decisions I had to make about my treatment was while I had stuff in my mouth making it almost impossible to talk. I had to type all my questions to the doctor which was fine but I would have preferred being able to talk it over ahead of time.

Dr Withrow and his assistant were very friendly and professional. They were very concerned about my comfort, my understanding of the procedure and asking if I had any questions. Dr. Withrow I thought had a very pleasant and professional doctor/patient "bedside" or in this case "chairside" manner.

Dr Withrow is always gentle and caring. I always go to him when I'm having tooth problems. This time he and the office manager stayed after work hours to perform a root canal for me as I was going on an extended trip the next day - above and beyond expectations - but I knew he'd take care of it for me - he always does!

He and his assistant were friendly, nice, funny (made me feel mentally and physically comfortable). The best part is he always, even before the root canal believed me when I said this one tooth hurts like it was all in my head according to other dentists and when he open it up he said, "I see an infection, now you know it was not in your head there really was a problem and now we are fixing it." That was great news and I was so happy I I teared up, the pain is virtually gone now. Thanks so much for believing and helping me Doctor. :)

waiting for an hour just to tell them they needed to pull my tooth. The time spent with someone was roughly ten minutes. I had to take time off work to wait around in the office and didn't feel the service was prompt at all. The doctor spoke in a bunch a words I didn't understand to the assistant and then looked at me and said basically we need to pull your tooth and then had me wait another 15 minutes just to tell me that he'll have my primary dentist call me. Very frustrating.
