Right away Dr. Kazemi and his great staff quickly put me at ease on a day nobody looks forward to. The anesthesiologist was terrific (slightly funny) and before I knew it I woke up and I was leaving in an hour feeling fine. They even walked me down the elevator and outside to where my father was waiting for me so he didn’t have to wait inside, I know with everybody wearing a mask these days you can’t see your facial expressions but I’m very sure if you could that the people in this office would be smiling. Job well done! Thank you all so much

I love doctor Young. He has been in my family for 5 years. He helped my husband during his time and was always honest and gave us multiple options when we needed it. I went to him today after turning the big 5-0 and during the whole process he was so responsive. He remembered me the minute I came in. He made me feel comfortable. I told him I was scared and he provided me all of my options and gave me the option to chose. I asked him which was the best option and he let me know right away. I was still nervous going in but I was reassured that he had my best interest. This is someone that you can go to for colonoscopy that will actually ease you through the process. Thank you Dr. Young!
