Dr Ross Hofmeyr

Founder & Medical Director

Medical Doctor (Specialist), Senior Instructor, Curriculum Advisor

Proudly South African, Ross was born and educated at the continent’s tip in Cape Town.  An avid outdoorsman with more than 20 years backcountry and mountaineering experience, Ross is most in his element in the rugged Cape Mountains, but a passion for adventure in wild places combined with his love of challenges has taken him from baking deserts to mountain peaks and frigid icecaps.  
Since qualifying from the University of Stellenbosch, his professional fields of interest have centred upon acute and critical care, trauma, anaesthesia, aeromedical, emergency and wilderness medicine.  He is a long-serving member of the mountain rescue team, Divemaster, and volunteer flight doctor for the Red Cross Air Mercy Service.  Ross has expedition experience from around the world, including serving as doctor and overwintering Expedition Leader for the South African National Antarctic Expedition.
After shifting his predominant focus of specialisation to anaesthesia and critical care, he now serves as a Consultant Anaesthesiologist and Clinical Research Fellow in Airway and Thoracic Anaesthesia at the University of Cape Town.  Ross’s research interests include all facets of airway management, aeromedical care, extreme physiology, point-of-care investigation, and thermoregulation.  He is a keen course director, instructor, speaker and #FOAM enthusiast with numerous publications.
A founding partner of WildMedix, he is responsible for the expedition medic program, medical protocols, clinical oversight and quality assurance.  When not providing care in the hospital or abroad, Ross is usually to be found in the wilds, committing random acts of aviation and/or adventure.
