      Dr Warneke was compassionate, respectful, down to earth, and totally present to me and my husband. By that I mean he looked me in the eye and heard what I was saying. He took his time as if he hadn't a care in the world or any other patient waiting in the wings. I have the utmost confidence in him being my oncology specialist.
