Dr. Andrew Dennis grew up in the 1970s watching Emergency, S.W.A.T. and Adam 12 - hit television shows that featured paramedics, police officers and an intrepid SWAT team. Today, Dr. Dennis lives all three of those shows.
He's a trauma and burn surgeon in Chicago's Cook County Hospital - one of the busiest urban trauma centers in the country - where he treats on average more than 20 critically injured patients a day. He's a sworn police officer and member/medical director of two Chicago regional SWAT teams. Dr. Dennis founded Citizen MD that teaches life saving tactics to law enforcement officers, educators and corporate leaders. Additionally, he is a surgical inventor and active clinical researcher.
As a trauma surgeon and law enforcement officer Dr. Dennis is unique in his ability to handle life threatening situations in the hospital and in the field. Through Medical Tactics, he has developed an educational program to teach non-emergency workers how to handle trauma situations - whether that involves workplace violence or a distraught teenager intent on shooting up a school. He is widely quoted in the media as an expert who speaks about law enforcement and trauma care.
