Dr. Deng is a horrible doctor. I only went there following my favorite PA who has already left because of how horrible he is. I have a perfect set of circumstances that make one lab test show up bad when it isn’t. It has actually been written about in JAMA. I saw him one time because my PA was out sick and he started in on my meds being wrong because of this one test result. Completely ignoring that all my others were in perfect range. When I tried to tell him this he told me to be shut up he was talking. He said he was the doctor and I didn’t know what I was talking about. Well the 3 specialist I have seen over the years all say I’m right, JAMA says I’m right.... but besides that I don’t appreciate being told to shut up.
