How likely are you to recommend Dr. Weiss?

(Select your rating)
I have come to know, respect and admire what an amazing MD he is but it's beyond that. He's an amazing Human being. After only being his patient for a few years, I had a major crisis which lasted 21 days in the hospital. He was honest, empathic and was so respectful of my situation, Thankfully, I do not need Dr. Weiss every week or every month, but when I received notice of his retirement, as happy as I am, I felt a sense of panic. No one knows more about me than this amazing, humble MD.
