As a cancer survivor, I am blessed to be able to see Dr. Koc every 6 months for the last 10 years. He has an excellent bed side manner, shows genuine care and concern for any questions, and takes the time to listen to what I have to say during the appointment. I have never had to wait more than a couple of minutes when I had an appointment with Dr. Koc (and most of the time, I don't have to wait at all). He is prompt and efficient. His job is not easy, but he maintains a calm, professional demeanor at every encounter (and he has a good sense of humor).
