Colon and Rectal Clinic Provides Surgical Fellowship Training

CRC Houston Surgical Fellowship Training In addition to providing quality and experienced colorectal disease treatment to its patients, the Colon and Rectal Clinic (CRC), with its roots in the Texas Medical Center, has been training general surgeons in the specialty of colon and rectal surgery for over 30 years.

Dr. James Hampton, a prominent and highly talented colorectal surgeon in Houston, had the vision of building a colorectal surgical clinic that would serve the needs of Houston's growing community. In 1971, CRC founder Donald R. Butts, M.D.,F.A.C.S. became the first graduate of the fellowship program which is affiliated with the University of Texas Medical School at Houston. In 1975, CRC assumed management of the program. Currently, Dr. Michael Snyder is the fellowship program director.

Since that time, more than 100 surgeons (including 20 women) have completed training in the CRC program and are in practice throughout the United States as well as Australia, Canada, Italy, Hong Kong and Mexico. Our training program prepares fully trained general surgeons for board certification in colon and rectal surgery.
