Juan Speroni

Guide: Aconcagua

Juan was born in Buenos Aires, but grew up in the province of Salta. It was there, surrounded by a landscape framed by the imposing Andes mountain range, that he took his first steps on those 3000 and 4000-meter peaks. He developed a love for climbing in adolescence, and quickly began to navigate 5000 and 6000 peaks with ease. In 2000 he summited Aconcagua, marking the first of countless expeditions to the top of the peak. After becoming certified by the Argentine Association of Mountain Guides, Juan established an impressive international guiding career, with successful expeditions in Argentina, Bolivia, Peru, and Patagonia. Aside from guiding Aconcagua expeditions with Alpine Ascents each season, he also guides independently across northwest Argentina and Chile.
