From the beginning, our mission has been a simple one, “Be a premiere Aconcagua expeditions outfitter, committed to providing the finest-quality trips, with highest safety standards and care for every client.”
Even if we are a new company, Martin Grech and his wife Valeria Martin have more than thirty years in the Aconcagua´s world.
For twenty years Martin and Valeria provided leadership to some of the most important companies in the industry. Today their names are respected and well known in the world of climbing, synonymous with the talent and ethical job.
Ascending Aconcagua as a 16-year-old, Martin began his trajectory from mountain climber to mountain guide to an executive. With 30 years of experience, Martin has been offering his support and professionalism to more than 1,200 expeditions from all over the world.
