"Doctor Rufner isn't just great he's amazing! Very thorough, derailed, took the time to explain things in great detail, didn't rush at all just simply amazing. You can tell he really cares and has compassion for me as a patient. I also noticed he was trying to take more of the natural approach of healing instead of expecting a medication to mask everything. I really wish all doctors now days were as organized and patient as he is. In this day in age it's very hard to find good care, I feel I have truly gotten extremely lucky"
