These episodes are a must listen for anyone curious about all things drowning. From professionals to public.

Dr. Justin Sempsrott is an emergency medicine physician and drowning specialist who’s spent the last two decades advancing drowning resuscitation. We split this episode into a two part recording in order to discuss in detail everything from physiology to advancements in care, global policy, studies, science, and every aspect of drowning management from prevention, to water rescue, conscious victims, and all the way to the hospital. Justin's extensive experience is a valuable asset to the lifeguard project podcast as it makes our community in tune with the latest updates in the world of water rescue and drowning prevention.

Justin started as a beach lifeguard in Jacksonville Beach, Florida in 1996. In 2006, he co-founded Lifeguards Without Borders after seeing the massive and preventable global burden of drowning, especially in low- and middle-income countries.

He’s provided consultation, training, and medical education across the world working with lifeguards, nurses, physicians, and responders in places like Peru, Portugal, India, Bangladesh, Vietnam, Australia, Nicaragua, Ecuador, Canada, and beyond.

In the last five years alone, Justin has lectured on drowning resuscitation to more than 10,000 prehospital providers including U.S. Air Force PJ’s, Navy SEALs, and other special operations medics. He has also helped spearhead numerous studies which have become the latest science for industry wide as well as statewide drowning protocols, most recently in San Luis Obispo County and in conjunction with the Lifeguard Project.

He also brings experience from wilderness medicine and mass gathering medicine, serving as Associate Medical Director for the Burning Man Medical Operations and continues to work in several emergency departments.
