Dr Gavin Johnson


Medical interests: Gastroenterology, endoscopy, ERCP, pancreaticobiliary medicine, gastroenterology and endoscopy training.



As a Gastroenterologist and a dedicated medical educator I am able to bring the very latest evidence-based medicine to my practice. I find the most rewarding aspect of my work is spending time with patients so that I understand their concerns and so that they are fully involved with their management and treatment plan. I see patients with a variety of abdominal and intestinal complaints; my specialist interest is endoscopy (including ERCP), and pancreaticobiliary medicine.


I see patients with problems or symptoms related to the liver or the digestive tract. My specialist interest is in panceaticobiliary medicine (problems related to the bile duct and panceas) and specialist endoscopy, including ERCP.
