Damian Brezinski has used all kinds of equipment to save lives, including stethoscopes, stents, defibrillators and guitar picks. Whether it’s teaching some of the biggest names in the music industry (Kenny Chesney, Def Leppard, Justin Bieber, Maroon Five) how to do CPR, or inserting balloons into a patient’s artery to treat heart disease, Damian has made it his life’s work to keep the heartbeat, and the music beat, alive.
