    How was your appointment with Dr. Greenstein?

    Jan 25, 2022
    Dr Greenstein has done two surgeries on my son, an ileostomy and then a reversal. Both were done laparoscopically with great success. There is no doubt Dr Greenstein is a talented surgeon but he also has an excellent bedside manner. He was always available to answer our questions, didn’t rush out of the hospital room and gave us flexibility since we live out of state. His office staff was responsive and very easy to deal with. We are so very grateful to Dr Greenstein and his staff!
