Dr. Yan is truly a lifesaver for my parent, who was hospitalized for two months due to severe pneumonia. With remarkable precision, he diagnosed the root cause as vasculitis and immediately initiated the appropriate treatment. Thanks to his expertise and swift action, my parent’s life was saved. We are deeply grateful for his care and dedication.

I was in the hospital for a week feeling very ill. Five doctors and all their tests couldn't figure out what was wrong with me. One day Dr Yan, (new to me), said he was reviewing my case and had an idea of what I had. He was correct! Also I had a rare disorder. Dr Yan is a life saver to me! I am constantly amazed at how intelligent and wise he is. His compassionate and caring bedside manner is very genuine. I'm so thankful he walked into my hospital room 11 years ago!

I have dealt with a lot of nephrologists, but he is by far the best and the most educated. He is very patient and genuinely wants to help his patients as much as he possibly can. He goes out of his way to find solutions for problems and help his patients. He is very caring and always has his patient's best interest at heart. He is not just a great doctor, but also a great human being.

Had a 4way by-pass and having kidney failure, was told by another Doctor I would not make it without my kidneys shutting down. Dr Yan said he felt he could overcome this and he DID.
