Meet the Global Adventures Team

Ronnie Muhl


In 1979, Ronnie Muhl read The Impossible Victory by Peter Habeler, and this was the birth of his passion to climb Everest. His dream came true in 2007 when he summited Mount Everest from the North Side. Ronnie has also climbed Kilimanjaro, Aconcagua, Denali, Elbrus and Kosciusko, put together the first South African expedition to Broad Peak in Pakistan, and has also been known to scale a few rock climbing routes.

He was born in the Johannesburg region of South Africa and now lives on the southern point of South Africa in a village called Simonstown. He is married to Elizabeth Bool, who joins him on all of his adventures and is as passionate about the mountains as he is. He has three incredible children and is someone who continually strives to be a better father, husband and human being. Ronnie has extensive experience as a team leader and is passionate about helping others achieve their dream and change their lives.

Elizabeth Bool


Elizabeth first trekked in the Himalayas in 1987 and her passion for the mountains was then born. She returned in 2011 to trek to Everest Base Camp on her own and without a porter. She accompanies Ronnie on all of his expeditions and has summited Kilimanjaro and Elbrus, besides having spent extended time on Aconcagua and in the Base Camp of Everest during the expeditions that Adventures Global runs on both sides of the mountain.

She assists with all international logistics and travel arrangements for all of the expeditions run by Adventures Global, and is a firm proponent of the idea that people should fill their lives with memories and not things.

Shelli first discovered a passion for adventure travel when she joined Adventures Global on a trip to Everest Base Camp in November 2016. Since then, she has become a fierce ambassador for the Adventures Global brand, while also handling their social media, blogs, newsletters and communications. Shelli recently completed the challenging Machu Picchu Inca Trail in August 2017 and plans to tackle the Camino de Santiago pilgrimage in Spain in May 2018 and Great Wall of China in 2019.
