Shaun Gogarty, MD

Truly understanding addiction is at the root of addressing it, and few people have had first hand experience with addiction like Dr. Gogarty. More than two decades as an emergency physician put him at the forefront of the opioid crisis. He witnessed the devastation as ever-increasing numbers of people were injured and killed by heroin. Worse, he dealt with the crisis personally as it unfolded in his family. A science educator before becoming a physician, Dr. Gogarty can make the most complicated topics easily understandable. Presently practicing addiction medicine keeps him attuned to the struggle of this problem. His extensive experience presenting to everyone from medical and behavioral health experts to elementary school students has honed his ability to help all people fully understand the tragedy of opioid abuse disorder and yet provide hopeful solutions.
