Gavin Barr graduated from UNSW with MB. BS (Hons1) in 1976. After postgraduate training at Sydney he was admitted as a FRACP in 1983. He spent 2 years in Oxford pursuing further clinical and endoscopic work as well as research into inflammatory bowel disease (IBD).

He then returned to Australia in 1984 and established his Gastroenterology practice, with rooms in Mosman and Macquarie St. He has a vast experience in all aspects of Gastroenterology and Hepatology but his particular interests have been in IBD, interventional endoscopy and functional G-I disorders.

He is a member of the Gastroenterological Society of Australia, is also a Fellow of the American College of Gastroenterology and is currently fully accredited in endoscopy, colonoscopy and ERCP with The Conjoint Committee for The Recognition of Training in Endoscopy and has an exceptionally low complication rate from all procedures.

Gavin is well known for his ready availability and prompt communication with GPs. He has a commonsense but thorough approach to clinical problems. He particularly focuses on detailed history taking, to not only help achieve a clinical diagnosis but also to rationalise investigations and management strategies.
