Our Faculty

AdventureMed is led by a group of motivated outdoor enthusiasts who believe that quality first response care is critical for community safety, and should be available to anyone regardless of environment or background.

AdventureMed’s faculty is comprised of medical professionals with extensive experience in wilderness medicine. The majority of our faculty and staff have extensively taught Advanced Wilderness Life Support courses, and have practiced wilderness medicine as both an avocation and occupation. We prioritize in-field experience, and continued hands-on experience and education for our staff.

Their professional affiliations include: major teaching universities, The U.S. Army, search and rescue teams, National Ski Patrol, and the Wilderness Medical Society. Many of our faculty have taught our courses since its inception, and have practiced wilderness medicine as both an avocation and occupation.

Our experienced instructors and collaborators have contributed to many of the currently accepted protocols for the treatment of injuries and illnesses in wildnerness environments.
