I have gone to Dr. Warren for years and have generally been happy with the treatment, facilities, scheduling, billing, etc. I had a few bad experiences with one particular hygienist who talked so much that she didn't pay attention to her work, and would frequently jab my gums or lips . However, all the other staff and the doctors have been pleasant and professional, and they usually provide me a free toothbrush, floss and mouthwash after each visit.
