Kevin Vann

Critical Care/ICU/Trauma Registered Nurse and trekking guide. Graduate of the Arizona Heart Institute and specializing in cardiovascular medicine. Kev is now one of the very few people on the planet to have summited the 7 summits – the highest mountain on every continent – Everest in Asia, Aconcagua in South America, Denali in North America, Kilimanjaro in Africa, Elbrus in Europe, Mount Vinson in Antarctica and Kosiosko in Australia. Notably, he has also climbed Cho Oyu. He is the first person ever to canoe the entire length of the Duck River in Tennessee (268.5 miles…solo)!


Dre Marie-Kristelle Ross

Cardiologist, specializing in sports cardiology and cardiac rehabilitation. She is also a qualified diving physician and is involved in the field of high altitude medicine. MK first joined the guys in 2009 on an EBC trek and summit of Island Peak. Combining strength and compassion in equal amounts and an incredible capacity for organization, she brings an added dimension to the team. She has helped lead numerous treks to EBC and has multiple summits of Island Peak and Lobuche East. She has climbed to the top of Elbrus, Kilimanjaro and Aconcagua and summited Cho Oyu with Thundu and Rob. She tried to climb Mount Everest twice and was on the mountain at the time of the fatal avalanche in the icefall in 2014 and during the countrywide earthquake in 2015. These events have restricted her Everest aspirations, but have brought her ever closer to the region and people of Nepal that she so loves. Full disclosure… Rob is proud to say that he is MK’s husband!
