    Surprised w casualness and lack of preparation for meeting. He suggested the possibility of a test that was already ordered and he read results for the first time when I told him it was ordered weeks prior. No blood work suggested very surprised at the gloss over kick the can down the road approach.

    I trust Dr Lee implicitly

    The care provider concentrated mostly on his part as the surgeon. The problem that I mentioned about the device was left to me to follow up on.
