Graham Hornsey and Carmen Gloria Monjes are a husband and wife team who are the ground anchor of The Patagonia Mountaineering School, taking care of all the operational and logistical requirements. They have lived and worked in Patagonia together with their 12 year old daughter Karen for the last 16 years. During this time Graham and Carmen Gloria have amassed an impressive total of 30 years combined experience administering wilderness and adventure expeditions together with extensive experience working with government departments, authorities and non-governmental organisations.

Megan Irving, originally from the UK, has been walking in the mountains for as long as she can remember. But she never really expected to make a career out of guiding. Way back when, she was a member of The Patagonia Mountaineering School's second ever expedition. She was later invited to come back via our internship program. Through hard work and dedication, she has become a sterling guide. She has climbed in the Himalayas, Alaska, the US and Canadian Rockies, as well as the mountains of Europe. When she's not climbing, Megan enjoys cycle touring (she has cycled across Europe on a tandem bicycle) and cooking.

Joos Ilsbroux, originally from Belgium, came to Chile in 1995 and forgot to go home. After traveling all over South America, he became the first westerner to train with the prestigioius Venezuelan Alpine Rescue Team. He came back to Chile in 2002 and has been guiding ever since. He is a Wilderness First Responder, a Leave No Trace Trainer, and is an Avalanche Safety I practicioner. In the offseason, Joos enjoys climbing and trekking in the many mountains near Coyhaique.
