John Ross Clark: Caring, compassionate, listens. Very concerned with how the patient is doing. Knowledgeable at a very high level, Answers all my questions, thus demonstrates the patience of a saint. Modest to a fault. Wry sense of humor. Respected by everyone to whom I mention his name: other MDs, his office staff, and all the nurses I have met, as well as other patients.
