Choosing who leads you into the Himalaya is one of the most important decisions you'll make before your climb ; so here's exactly what that decision gets you.
IFMGA-Certified Leadership on Every Expedition
Every GMT Adventures expedition is led under the direct guidance of Gesman Tamang, an IFMGA-certified mountain guide and one of Nepal's most experienced high-altitude leaders. With six Everest summits, six Manaslu summits, and an Annapurna I ascent without supplemental oxygen behind him, the standards applied to your climb are the same standards he has trusted with his own.
21 Years of High-Altitude Rescue and Crisis Experience
Gesman has led numerous high-altitude rescue and recovery operations, including technical crevasse extractions and long-line helicopter evacuations on Everest and Annapurna. That experience shapes every route decision and safety call made on your expedition ;judgment earned in moments when it mattered most.
International Expedition Experience Beyond Nepal
Our leadership's experience isn't confined to Nepal. Gesman has led expeditions on Lenin Peak (7,134m) in Kyrgyzstan and Aconcagua (6,961m) in Argentina, bringing international mountaineering standards and a broader range of high-altitude experience to every Himalayan expedition we run ; from trekking peaks to full 8000m mountaineering expeditions.
Structured Training Before Every Summit Push
Every climber receives structured pre-summit training, tailored to the technical demands of your specific route ; whether you're heading to Everest Base Camp, attempting Ama Dablam, or taking on a full 8,000-meter expedition. You arrive at your summit push ready, not just acclimatized.
