The Division of Gastroenterology marks the academic retirement of Dr. Stephen Collins following a remarkable 45-year career at @McMasterU. From founding the Intestinal Diseases Research Institute and navigating its evolution to the @Farncombe_GI Farncombe Family Digestive Health Research Institute, supporting innovation at McMaster University Faculty of Health Sciences as Assistant Dean of Research, teaching and mentoring hundreds of trainees, and providing compassionate bedside care as a highly astute clinician, Dr. Collins has left indelible marks on our institution. Thank you! @CanGastroAssn @ontario_gastros @MacDeptMed

The @McMasterU Division of Gastroenterology bids a fond farewell to Dr. Smita Halder after 16 years of innovation, leadership and compassionate care for all of our patients with gastrointestinal disorders. Wishing her all the best as she takes on a new leadership role at Toronto Metropolitan University school of medicine! @Farncombe_GI @CanGastroAssn @ontario_gastros
