Dr. Haas serves as Chief of Division of Colon and Rectal Surgery and
 Director of Clinical Research and Quality Outcomes at University General Hospital. Dr. Haas is also a faculty surgeon at St Luke’s Hospital, The Methodist Hospital, and Memorial Hermann Hospital in the Texas Medical Center. Dr. Haas serves as a member of the New Technologies Committee, Quality Assessment & Safety Committee, and the Research Development Committee for the American Society of Colon and Rectal Surgeons and as such is heavily involved in the promotion of quality outcomes and best surgical practices. He is also an adviser on minimally invasive laparoscopic colon surgery for Applied Medical and Ethicon-Endo Surgery.

Dr. Haas earned his M.D. from the University of Texas Medical School at Houston, where he was inducted into the Alpha Omega Alpha Medical Honor Society. He completed his General Surgery Residency at St. Joseph Hospital, and his fellowship training in Colon and Rectal Surgery at The University of Texas Medical School Fellowship Program.

A nationally-recognized expert in advanced laparoscopic surgery for colon cancer treatment, Dr. Haas is also known for his expertise in benign diseases such as rectal prolapse, polyps, diverticulitis, inflammatory bowel disease, ulcerative colitis, pelvic floor dysfunctions, and Crohn’s disease. Dr. Haas has also developed academic and research programs that incorporate best practices following Minimally invasive colorectal surgery. His research program has published numerous manuscripts and publications in prominent peer-reviewed surgical journals. Dr. Haas and his research fellows have presented at prestigious surgical meetings throughout the world regarding laparoscopic and robotic techniques, single-incision surgery, best outcomes and minimally invasive approaches.
