Our Story

Our story begins with a couple’s passion – a passion for the greatest mountains in the world: the Himalaya. As guides and adventurers husband and wife team Sonam and Pasang Lamu Sherpa spent many years exploring the Himalaya’s magical valleys and ancient ways, setting the standards for mountaineering and climbing these magnificent peaks. The Sherpa people have traditionally been known as ‘the guardians of the Himalaya’

As Sherpa, we know and love this region and it is in this role that Sonam wished to share this knowledge and love with others. On his return from a season work in the French Alps, he knew he had to turn this journey of the imagination into a reality. In Sonam words “it was when standing on the summit of the 6,632m peak, Thamserku, that I decided to form a company that would offer everyone the opportunity to discover and appreciate the beauty and challenge of these awe inspiring mountains.” And so the Thamserku Company was born, establishing itself in a tiny office in central Kathmandu.
