The cast of Chicago Med has changed a lot throughout its 10 seasons, and although some actors leave, many eventually return, including Brian Tee. Tee starred as Dr. Ethan Choi in the first eight seasons of the One Chicago TV show, making him one of the medical drama's original cast members. When Chicago Med began, Ethan was a Resident in Gaffney Chicago Medical Center's emergency department. Eventually, he got promoted to Chief Resident, then became Attending Emergency Medicine Doctor, and, finally, the character ended his time on the series as the Chief of Emergency Medicine.
