Gastroenterology & Nutrition

The faculty of the Loyola Gastroenterology Division are nationally recognized for their expertise in general gastroenterology, pancreaticobiliary disease, inflammatory bowel disease, gastrointestinal behavioral medicine, and gastrointestinal motility disorders. We utilize innovative techniques and interventions to help serve our patient's needs. We work closely with other disciplines at Loyola to provide comprehensive and coordinated care for all our patients.

Our faculty are involved with clinical supervision, didactic teaching, and research mentorship for medical students, residents and fellows. We train up to 12 fellows and promote their development into clinical leaders in the field.
