Cerro Penitentes 2-day guided ascent in Mendoza

Andes Specialists is a guiding company founded in 2012 with a clear mission: to transform a passion for high-altitude mountaineering into a professional, adaptable, and reliable service. Created by Maximo Kausch, the company was born from his dream of turning a lifelong connection with the mountains into a project focused on deep knowledge, real guiding experience, and personalized service.

We operate exclusively in the Andes, not only in the most iconic mountains, but also in remote and rarely visited regions where few — if any — guides work. Our clients recognize us for our flexibility and ability to adapt to their goals, just like the mountains that inspire us.

All of our expeditions are led by certified guides, and we place special emphasis on a guide’s professional experience in the field — not just their personal climbing résumé. We believe that strong logistics, leadership, and group care are what truly define a world-class mountain guide.

Maximo Kausch, the founder, personally leads most of our expeditions. When he’s not available, clients are guided by handpicked members of his trusted team. Maximo has led over 10 expeditions to 8,000-meter peaks, several to 7,000-meter peaks, and more than 90 to 6,000-meter mountains. He has climbed over 250 extreme altitude peaks, reached the summit of K2, and currently holds the Guinness World Record for the most 6,000-meter peaks climbed — with 89 summits officially recognized.

At Andes Specialists, guiding isn’t just about reaching the summit — it’s about going beyond the obvious, with safety, expertise, and genuine connection.
