"As before, everyone at Central Illinois Endoscopy Center was fantastic! Dr. Penn was very welcoming and upbeat both before and after my procedure. The anesthesia they used was great, and I was clear headed enough immediately after to remember everything he told me. I would highly recommend Dr. Penn if you are in need of a colonoscopy."
