    "Dr. Rufner and his staff are always prompt, professional and pleasant. The subject matter when seeing an Gastroenterologist is not the easiest to discuss and yet Dr. Rufner has the natural ability to put the patient at ease when discussing symptoms, diagnoses and treatments. I recommend him without any reservations."
