How likely are you to recommend Dr. Sierocki?

(Select your rating)
Dr. Sierocki was my oncologist when I lived in Princeton NJ. He helped me very much when I was first diagnosed with gist (gastrointestinal stromal tumor) in my small intestine. He provided capable and competent support to me, both medically and emotionally, during a very uncertain and difficult time in my life. Although gist is fairly rare, he made excellent medical decisions before, during, and after surgery. His advice is very practical and effective.
