    She’s not warm or compassionate. She doesn’t explain what she’s doing for your care. She’s comes off as judgmental.

    She explains things so that I understand. Also Dr Nguyen believes in doing things naturally instead of pills. I have been that way for a long time. She is very caring. Dr Nguyen makes sure that things are corrected by retesting.

    The blood tests were, as I understand, sent to :LabCorp. In order to view the results, I had to establish an account, even though we have been going over there for years. The attempt to establish an account was a pain, and I just quit!
