Patient Reviews
Sep 24, 2023
Dr. Greenstein performed a Colon Resection on me in June of 2022. I travel almost two hours to get to his office but he is the best and came highly recommended. He and his surgical team are very down to earth and take the time to listen and respond to your concerns. For those of us that travel from a far they realize we are away from our families and they go out of their way to make us feel very welcomed at the hospital at all times. My surgery went well and the chemo that followed thereafter was not as bad as I imagined. He makes sure that the cancer center makes you feel as comfortable as possible. He is the best and I am happy to be alive thanks to him.
