I find that Dr. Mark takes all the time he needs to take to fully explain any illness you have. He will refer you to expert people and is a very sincere man trying to give the very best possible care. I even experienced him attending the wake of a patient who had passed on, giving explanation to relatives about the terminal illness. More like a real "small town" Dr. Welby! Great doctor. Has a head full of detailed info on illness and helps senior citizens out with samples at times.
