First visit with Dr Yan was good, considering the reviews on this page. Second visit was horrible. First, she took almost an hour to get into the room. Then she blatantly falsified my nerve test by forcing my legs to flex more than I could physically flex them, thus getting the results SHE wanted. She then skated over the fact that my MRI shows severe stenosis saying, "I see one, two bump but nothing to worry about." I said, "Then what's causing my issues?" She said, "What issues you have?" I explained everything again. Then she put me through the same battery of tests she'd done at my first appointment. Then she opened my lab work which showed several abnormal markers and said, "I see 1 low abnormal and I'm not worry about it." I asked about the others and, no kidding here folks, she said, "I'm not smart enough to diagnose your condition." I asked, "Then why are you a doctor?" She repeated, "I am not smart enough to treat you. You follow check out sign to exit."And left very quickly.
