The American Foregut Society proudly honors our distinguished members with the Fellow of the AFS (FAFS).

Unique by design, the American Foregut Society codifies the multidisciplinary standard to which we all strive. Becoming a Fellow of the AFS requires the expected commitment to excellence and a track record of leadership, but also requires the practitioner to move outside the silo in which they practice.

The AFS seeks to promote both academic and clinical collaboration from all those working within the foregut space; being designated a Fellow of the American Foregut Society therefore demonstrates the ultimate commitment to caring for patients with foregut disorders.

The American Foregut Society (AFS) brings Foregut Surgeons and Gastroenterologists together to advance science in the field, guide and foster collaboration, and positively impact treatment paradigms. Advancement to Fellowship within the society represents a commitment to high standards and continued progress. The title of Fellow acknowledges a Member’s prior achievements and dedication to improving care for patients with foregut disorders. Fellows will therefore serve as liaisons to the community, fellow practitioners, and patients as well as paragons of the modern practitioner.
