I have been working as a mountain guide in patagonia, for the last 20 years.Managed mountain hut, and climbing along the andes from Puna to Patagonia.And have time to teach calculus and physics in the university,(when bad weather reach mountains!!!).Traveled to Antartica for working in glaciology.Now I focused in treks in small groups, to places no so usual.Low impact tecnics, enjoy and care the nature, with the customers.
