Management and Operations

Jonathan Cassidy

Owner and Director

Jonathan had the good fortune to join a team of Bolivian guides on an expedition to Huayna Potosi in May 2000 and has kept in close contact with them since. He has been out into the mountains throughout the country countless times now with these guides and is extremely confident of their experience, ability and conduct with people of all levels of skill and experience. It is for this reason that he is working with them in this company.

He is likely to be the person you will deal with by email before departing for Bolivia. He has led and organised expeditions for a number of organisations throughout his career and has an accumulative experience of over 20 years working and travelling in South America. If you have any questions regarding these trips or any other area of travel within South America, you should not hesitate to ask his advice.

Miriam Centellas

Owner and La Paz Operations Manager

Miriam studied tourism at university and has since worked in the Bolivian travel industry for the past 20 years. As secretary for the Club Andino Boliviano for a number of years, her experience arranging and overseeing remote expeditions grew immensely. This post also means that she has been working alongside some of the country's most presigious and experienced guides for many many years.

She speaks English, French and Spanish and you will no doubt have some contact with her once out in Bolivia.

Itinerary Planning and Pre-Departure Support

Hugo Centellas

La Paz Operational Support

No Bolivian Mountains expedition will be without the careful attention to detail of Hugo, preparing food supplies and equipment - arguably the most important part of a successful time in the mountains. Just to add further weight to the family feel of this business, Hugo is in fact father of owner Miriam, and will quickly become the adopted father of everyone that comes to visit!

Guides

Jose Mamani

Leading Mountain Guide

A qualified mountain guide, Jose has worked in the mountains for the past 20 years and is one of our most experienced mountaineers.

He has completed courses from the National School of Ski and Mountaineering of France (ENSA), the Club Andino Boliviano, the Spanish Federation of Mountain Sports (FEDME).

He has worked with the Spanish and US embassies as a mountain guide, and currently spends about 50% of his waking life on the mountainside!

Felix Guarachi

Leading Mountain Guide - UIAGM Certified

Felix began enjoying the mountains at the age of 24, and took part in his first formal training with a team of German Alpine instructors in 1990. His list of ascents includes that of accompanying ex-president Jorge Quiroga on Illimani.

He also has trained and worked in mountain rescue - both on rock and ice - and has worked as an mountain rescue instructor for the Military Geographical Institute of Bolivia.

He has completed the ENSA mountain training course, and was certified as a UIAGM guide in 2005.

Cecilio Daza

UIAGM Certified Guide

Cecilio is one of the most qualified local guides in Bolivia. In 2000, at the age of 26, he took part in a mountain course organised by ENSA in Bolivia, and then moved on to gaining the IUAGM aspirant guide title in 2005. His skills and abilities clearly stood out in that last course, as he was offered a scholarship to travel to Chamonix in 2007, and was sponsored to become qualified as a full UIAGM guide at that point.

He has since guided many delegations from embassies and other diplomatic entities throughout the ranges in Bolivia, and we are delighted to have him as part of the team.
