I have rarely seen so many virtues in a doctor. In addition to guiding me through my ulcerative colitis process and explaining the steps to follow and potential problems thoroughly and repeatedly, I can say that Dr. Faiz is a highly experienced IBD surgeon, even anticipating possible complications. It is also worth highlighting his accessibility and calmness, which are so important during tough times."
