    How was your appointment with Dr. Klonsky?

    Jun 30, 2021
    He is the best general surgeon. I’ve gotten two surgeries from him and he is the best. He’s really nice and friendly. Very caring and tells you everything you need to know. I would recommend him to anyone. There is no other surgeon like this one! I’ll be coming here for every surgery I need.
