Mark Hanak, MD
Resident Physician, Class of 2023
Department of Anesthesiology Featured Member: February 2021
Mark is one of the current CA-1 residents in the Department of Anesthesiology. Originally from the Washington D.C. suburbs, he attended the University of Virginia for both undergrad and medical school. Following graduation he moved to St. Louis with his girlfriend, Alison, who is an OBGYN resident here at WashU.
When choosing a residency, he was drawn to the department’s diverse faculty and clinical opportunities. “I wanted to be able to learn from not just the national but also international leaders in the field. There are many ways to approach anesthetic management and getting to train here broadens one’s perspective.”
Outside of the hospital, Mark enjoys running, snowboarding, cooking, attending concerts (pre-COVID), and spending time with Alison and his 1 year old Pyrenees/Shepherd mix, Osley. They recently moved into a house and Mark is excited to start up a home garden this Spring.
