Dr. Gu should not be practicing medicine. I have never met a doctor less caring, less professional and less involved with his patients care than Dr. Gu. He is administratively and technology challenged and he gets annoyed and agitated when you ask any questions about your treatment. He also never calls to tell you the results of your scans when they have been posted in the portal for over a week. Dr. Gu should not be patient facing as he is unable to explain anything about the treatments he is providing. When he finally blesses you with his presence (which is rare), he offers no useful information and only gives one word answers if you are lucky enough for him to even answer your question. I am surprised that MSK would tolerate this type of care from one of their doctors. read more
