Michael Semple, DO
Dr. Michael Semple grew up outside Denver, CO. He attended the University of Colorado at Boulder for his undergraduate studies majoring in biochemistry and minoring in chemistry and history. Afterwards he went to medical school at ATSU Kirksville College of Osteopathic Medicine, then completed emergency medicine training in Detroit, MI at Beaumont Farmington Hills hospital. He worked in underserved community hospitals in St. Louis for a year prior to returning to training and starting Toxicology fellowship here at Barnes-Jewish Hospital. Originally Michael’s interests in toxicology started in undergrad while obtaining his biochemistry degree, now his interests have blossomed towards plant and mushroom toxicology…as well as corny jokes. Away from the hospital Michael enjoys any activity in the mountains, especially skiing and hiking. In addition, he plays hockey weekly, after which he regales anyone in the office that’s willing to listen about how he put the puck “up top where momma keeps the peanut butter” (we aren’t sure what he is talking about).
