Cleveland Clinic's Colorectal Surgery educational program offers a 1-year ACGME accredited residency following the completion of a general surgery residency in the US or Canada. Our four ACGME positions are filled through the national residency matching program. In addition, we offer a 1-year fellowship for international trainees who have completed their general surgery residency. Appointments to the fellowship are made on a competitive basis and can be initiated via communication with our chairman, educational program director, or coordinator.

Our educational goal is to improve the knowledge and skills of our trainees in the full spectrum of colorectal surgery. Opportunities include patient evaluation and management, critical decision making, operative skills, clinical research, residency and hospital administration, medical student teaching, and a structured teaching program and conferences.

Our surgical staff includes over 20 surgeons with diverse clinical, research, and administrative expertise and interests. Many are well-known leaders in the field.

Colorectal Surgery continues to change and evolve with increased understanding of pathophysiology, enhanced technologies, and multi-disciplinary approaches to improving treatment outcomes. Our department is at the forefront of these advances, with a commitment to educate our trainees to become leaders in their chosen field.

Training Environment

Our residents develop a rich clinical experience across the spectrum of surgical practice: a quaternary care research hospital, high volume community hospitals, the major regional trauma center and safety net hospital, and ambulatory surgical centers. All of our locations have excellent nursing, case managers, ancillary staff levels (with physician assistant on each service and physician assistant and general surgery junior support on the high volume services) allowing fellows to concentrate on their role as surgeons. One rotation per academic year will be spent in our regional service, which is comprised of our Beachwood Surgery Center and Hillcrest Hospital.

Cleveland Clinic

Cleveland Clinic was founded in 1921 by George Crile Sr., a general and endocrine surgeon; Frank Bunts, a neurosurgeon; William Lower, an urologist; and John Phillips, an internist. It was a new kind of medical center: a physician-lead, not-for-profit, integrated hospital and group practice, equally dedicated to patient care, research, and education. Cleveland Clinic quickly became a world renowned training hospital, medical school and research institute, known for offering the most advanced medical care. Cleveland Clinic's main campus consists of 41 buildings and more than 85 operating rooms, with constant expansion and renovation. Cleveland Clinic’s subspecialty surgeons are at the forefront of surgical care and are behind its reputation as a top-ranked, quaternary care hospital with an international referral base, and high volume critical care transfer service, that cares for the most complex patients.

Cleveland Clinic is immediately adjacent to the University Circle Neighborhood, home of the Case Western Reserve University, the Cleveland Orchestra, and the Cleveland Museum of Art. Cleveland Clinic is centrally located and accessible from the downtown, east, and west side residential neighborhoods.
