Everyone was so nice! Dr. Townsend and his assistant were great! They let you know what was going to happen during all the procedures and always asked if you were OK and comfortable with everything. I will definitely go back if I need to, and would gladly refer others to go there.

I 100% recommend Great Northern Endodontics to everyone!! The entire staff is so welcoming that I felt totally relaxed. This was the second time I had had a root canal, and I actually looked forward to being there again! Dr. Townsend is so caring and thoughtful that he keeps asking if it hurts! I experienced absolutely no pain from beginning to end. Plus…. He has a tv above the chair for his patients’ entertainment!! Dr. Townsend and his staff are the best ever!!
