University of Texas Affiliated Hospitals


In 1971 Dr. Donald Butts became the first graduate of The University of Texas Health Science Center at Houston Colon and Rectal Surgery Residency Program. One year later, Dr. Butts and Dr. James Hampton joined their separate practices to form Colon and Rectal Clinic, which has been the cornerstone of the institution's ACGME colon and rectal training program. Dr. H. Randolph Bailey joined the clinic in 1974 and was a major influence in the program as Program Director and Chief of Colon and Rectal Surgery at UTHSCH for over 20 years. Dr. Michael J. Snyder graduated from the UTHSCH program in 1998 and became the Program Director in 2005. In 2015 we became UT Physicians Colon and Rectal Clinic. The program currently has twelve board certified colon and rectal surgeons, many of whom trained under our direction. Our physicians have 128 years of experience in the specialty collectively. We are fully committed to your training and are confident that your experience with us will prepare you for a successful clinical and/or academic career as a colon and rectal surgeon.
