I have seen this doctor a couple of times in the past, once for a colon resection and was happy to be referred to him for my current medical problem. He is the BEST!

Had my consultation with dr Casillas yesterday for my colonoscopy and polop removal surgery slated for December. He was kind, compassionate, and explained everything that I am to be expecting for my upcoming surgery. His staff made me feel comfortable, answered all my questions and eased a lot of my stress.
