Board Certified American Board of Colon & Rectal Surgery

Clifford Simmang sees patients from all over Central and West Texas. His patients choose to travel the extra distance seeking his extensive experience and naturally gentle, caring disposition. Many have expressed similar sentiments:

As a leader in the field of colon and rectal health, Dr. Simmang served as one of only five members on the Laparoscopic Education Committee for the American Society of Colon and Rectal Surgeons. As the top recognized national experts, these five surgeons were responsible for teaching all Fellows training in colon and rectal laparoscopic surgery on a national level. He continues to lecture and teach advanced laparoscopic surgery around the country. He has almost 100 articles published in various medical journals and has served on editorial boards for four of those journals.

Even with the travel demands of his professional responsibilities, Dr. Simmang makes time for each patient in his office and carefully and personally discusses their diagnosis and treatment. He is always happy to answer questions and share a bit of his immense knowledge. He specializes in sphincter sparing procedures for rectal cancer, laparoscopic colorectal surgery and the evaluation and management of hereditary colorectal cancer conditions. His practice encompasses colorectal disorders including Crohn’s disease, diverticulitis, hemorrhoids, and screening, diagnostic and therapeutic colonoscopies.
