My experience with the doctor and his assistant was great. My tooth extraction went well. I was very nervous but they explained everything and was very patient. They were very pleasant and professional.

I was there for an extraction and an implant. I was dreading this so much, and so scared, but procedure went very quickly. Only had a slight bit of discomfort. Everyone was very nice and did their best to explain everything and reassure me. Dr. Then was wonderful. Would definitely recommend this practice!
