Bill Reese, WFR

As a teenager, Bill formed an interest in medicine and training while helping his mother become a Registered Nurse. Realizing the rewards of training and education, he began a lifelong, progressive path of medical study. After learning the basics of first aid and sports injuries while serving as a football coach, Bill became a Radiology Assistant at a local hospital, where his knowledge of human anatomy and physiology were further developed. Since then he hasn’t stopped learning. He continues to use his skills to unofficially address the needs of injured and ill patients across the globe. Bill has encountered patients suffering from malaria and tuberculosis in the Democratic Republic of the Congo (DRC), malaria and influenza in Ghana, routine injuries and exotic insect bites in Jamaica and Mexico, and even heat-related illness in Peru. Seeing the value of medical training when separated from definitive care, Bill earned his WFA and WFR certifications, and is a graduate of The Pathfinder School’s Advanced Survival Program. Bill’s wide range of study in other countries as well as in various parts of the United States has provided an expansive knowledge around improvised medicine in austere environments.
