Dr. Zelkowitz exceeded my expectations and then some. I was diagnosed with breast cancer 5 days before my visit with him and had no idea what to expect. Dr. Zelkowitz took time to speak with me and my mother and husband (who had lots of questions). He could see I was overwhelmed and explained everything step by step. Additionally, Dr. Zelkowitz moved quickly to help plan for the next steps. I loved his caring and direct approach.

This review is for Dr. Zelkowitz! He is the best oncologist. He is caring, smart, up to date on current science and medical thinking. If every physician would be like him, this world would be a much better and healthier place! Can’t recommend him enough! (Or maybe I should keep him a secret so we can get our appointments easily.) 😉
