Dr. Mark has been my primary doctor for many years. I still come back to him as my primary doctor even though I live and work in California temporarily. He's very courteous, listens, and spends time during my visit. I trust his recommendations. And when I need something like work related issues, like clearance, I can get results mailed to me. Only thing, when I call the office, it'll take couple of days to get back to me. In general, service is great!!
