How likely are you to recommend Dr. Shum?

I honestly have not met a more amazing doctor. I saw him TWO times after being diagnosed and after coming from a “hot shot” Beverly Hills oncologist, Dr Shum was 5 stars! He spent so much time with us going through treatment options, pluses and minuses of each treatment method, and was patient and pleasant. Amazing bedside manner which other doctors DO NOT have. He even thinks “outside the box” which many doctors do not. I don’t have enough amazing words to describe how good I feel!
