    "Dr. Rufner is just amazing! His treatment plan got me into remission, and it is always a pleasure to visit him. I’m not one of those people who are afraid of doctors/hospitals, but if I was Dr. Rufner would most certainly change my mind in that regard. He is very attentive to your concerns, and always explains his treatment decisions thoroughly. Every time I leave his office I feel confident that we have made the right decision for me and my treatment plan. Thank you Dr. Rufner!"
