Again, very thorough. DR. Unnithan always investigates to get to the root of any problem I may have. I can explain my concern of a pain. I don't come in with minor pain. She sent me to a couple of Doctors. Turns out I had a gallbladder removal and two kidney surgerys last year. I now have another issue. I had a CT scan amd Xray. I some sort of spine issue. Still waiting for results. Like I said, she really wants to get answers. I am so satisfied, so grateful.
