I am Marc Pullis, the Safety Coordinator at Hennepin County Medical Center (HCMC) in Minneapolis, MN. I was first introduced to diving in 2003 where I served as an EMT / Firefighter in the Marshall Island on Kwajalein atoll where I obtained my advanced SCUBA diver license. I began my professional career in hyperbaric medicine in 2007 at HCMC while working with both a Vacudyne quad-lock multiplace and ETC monoplace chambers. In 2012, I was made Safety Coordinator while installing a new Fink Engineered triple-lock multiplace chamber. My specialties include developing and implementing a preventative maintenance and education programs, design and development of hyperbaric components and ancillary equipment needed for safe and successful treatments of both chronic and emergent treatments.
