A TRAGIC LOSS BECAME A LIFESAVING MISSION

Greg Creswell lost his life during a choking emergency in a crowded restaurant. His family founded GregO₂ so more public spaces could be prepared—and fewer families would experience the same preventable tragedy.

Our Mission

GregO2 exists to prevent choking deaths, by placing anti-choking devices where people eat and gather, and by teaching people how to respond in the moments before EMS arrives. We started in Chattanooga, and we're not stopping here.
