Colon and Rectal Surgery Team

The Colon and Rectal Surgery team offers high-quality care for patients with disorders of the colon, rectum, and anus. We collaborate with many providers at our medical center to ensure you receive complete and personalized care for your condition.

Our medical center is also an academic center, or teaching hospital, which means that in addition to offering expert care for our patients, our doctors also educate residents and medical students in the fundamentals of colon and rectal surgery.

You will meet some of us at your first visit. Your initial care team may include a surgeon, associate provider (nurse practitioner, physician assistant), nurse, resident, and medical student. Depending on your condition and treatment, your care team may expand to include a dietitian, wound ostomy care nurse, medical oncologist, radiation oncologist, radiologist, gastroenterologist, urogynecologist, pathologist, and providers of support services.

For patients with rectal cancer, your care is coordinated by a rectal cancer multidisciplinary team, which includes physicians specializing in colon and rectal surgery, radiation oncology, medical oncology, pathology, genetics, and radiology.

We take pride in giving you the best care possible.
