A medical doctor, Dr Mark Trozzi has been practicing Emergency Medicine for the past twenty-five years. Graduating in 1990 from the University of Western Ontario, he is an Advanced Trauma Life Support professor with the College of Surgeons of America, and holds teaching positions at Sunnybrook Health Sciences in the Advanced Life Support Department, as well as with both Queen’s University and the University of Ottawa. On call in multiple emergency units during the Covid-19 pandemic, including an ER designated specifically for Covid-19, he now refuses to participate in practices he considers unethical and unscientific, that have been imposed by Covid-19 policies. He currently dedicates himself full-time to research, public education, and activism and is an active member of Take Action Canada and Canada Health Alliance. Mark is also a Director of EbMCsquared CiC. His written and video material can be found at www.drtrozzi.org.
