Dr. Casillas is a very skilled, knowledgeable surgeon. He takes the time to thoroughly explain procedures and options. His calm demeanor is very reassuring. I was so impressed with him, and so grateful for the excellent outcome of the surgery.

My last visit was my last visit. Dr Casias,in my experience, choses not to communicate with other surgeons on my case. He blindly performed a procedure without imaging or the experience of someone more qualified and as a result. My life has been impacted in a very difficult way ever since. I regret that I trusted him. He did exactly the opposite of what he told me he would do. Problem is ,he knows it and refuses to take personal responsibility and simply say,I'm sorry this happened.

Dr. Casillas took over practice of Dr. Julio Solla whom I used for 15 years. Dr. Casillas is incredibly thorough, very "patient sensitive" and is another one of the exceptional bright Stars at UT Medical. It takes a very special physican to practice in the Colon / Rectal arena, he's tops. Had a recent colonoscopy, he was very thorough with diagnosis to find diverticulitis, discussed treatment options, etc. Engages and listens to patient very well. Highly recommend.
