The mission of the College, founded in 1932, is to advance world-class care for patients with gastrointestinal disorders through excellence, innovation, and advocacy in the areas of scientific investigation, education, prevention, and treatment.

More than 18,000 physicians from 86 countries are members of the ACG. Through annual scientific meetings, the American Journal of Gastroenterology, Clinical & Translational Gastroenterology, and the ACG Case Reports Journal, as well as regional postgraduate training courses and research grants, the ACG provides its members with the most accurate and up-to-date scientific information on digestive health and the etiology, symptomatology, and treatment of GI disorders.

ACG's advocacy in the public policy arenas and the work of the ACG's 24 committees have made tremendous strides with many premiere accomplishments to improve the future of clinical gastroenterology and the quality of care available to patients with GI conditions and diseases today. The information exchange and training acquired through College membership provide physicians with the knowledge necessary to offer the most effective patient care and to meet the challenges of today's changing health care system.
