Short Bio

Dr. Trotter was born in Ottawa but grew up in Vancouver and received most of his post-secondary education at the University of British Columbia (BSc – Physiology- 1981; MD 1985, PhD 1990). Following his Anatomic Pathology Residency at UBC, he did a Dermatopathology fellowship for one year in London, U.K., at St. John’s Institute of Dermatology. Dr. Trotter is a Diplomate (Dermatopathology) of the Royal College of Pathologists (U.K.)

Dr. Trotter began his career as a pathologist at Vancouver General Hospital in 1994, and moved to Calgary in 2000. He was the Division Head, Anatomic Pathology and Cytopathology for Calgary Laboratory Services and the University of Calgary from 2002-2008, acting Department Head 2004-2005, and directed the immunohistochemistry laboratory from 2003-2014. Dr. Trotter returned to Vancouver in April 2015 and is currently the Head of the Department of Pathology and Laboratory Medicine at Providence Health Care. His major research interests are in skin cancer, especially melanoma, and in workload/quality assurance issues in laboratory medicine.

Dr. Trotter is the Past-President of the Canadian Association of Pathologists (CAP-ACP) and has served on the CAP-ACP Executive off-and-on since 2001. Dr. Trotter is married with three grown daughters. If he could spend all his time hiking, climbing, and skiing, he probably would!
