      The only slight negative was that it all felt a bit rushed. Nevertheless I was given numerous opportunities to ask any questions that occurred to me however as a 72 year old it's hard to keep up sometimes hahaha

      He is very straightforward, no sugarcoating, which is what I want in a doctor. What I have is devastating, his words are truthful, but also comforting in his tone of voice. Will definitely keep him as my oncologist and recommend him.

      It was a very solid conversation with really good information and direction. We felt Dr. Allen was sincere and knowledgeable.
