In Tendi’s Own Words…
My name is Pasang Tendi Sherpa. I was born in 1983 in Sankhuwasabha district, in a very remote mountain village in the eastern part of Nepal called Khembalung.
I started my career as a trekking porter at the age of 13 years old, and my first summit of Everest was in 2004 when I was only 21 years old. To date, I have summited Everest 17 times and many other mountains in Nepal, South America, North America, Antarctica, Europe, New Zealand, China, and Africa.
Besides my climbing profession, I am deeply involved with my own charitable organization, Tendi Sherpa Foundation, and Nepalko Sathi Association to support the poor community in the remote villages of Nepal. So far, we have supported more than 60 children with the scholarships, built two suspension bridges, and a monastery in the Khembalung region.
After many years of mountaineering training, I finally passed the high-level mountain guiding course in 2011, which is affiliated with the International Federation of Mountain Guides Association (IFMGA).
I have been travelling around the world for public conferences over the past 11 years, and among them, I have had the opportunity to give a talk at the headquarters of Facebook, Apple, and Google in LA, USA, and I was invited as the guest of honor for the Mountain Film Festival in Switzerland and France. During my traveling around I got chance to be interviewed featured in many popular news medias such as BBC London, CNN, Times Radio UK, RTS television Swiss, TV5 Monde France, National Geographic Magazine and many others.
I am a Co-Founder of the Himali brand, which is a brand for mountaineering apparel based in Boulder, USA. Through this brand, we were able to help the Tengboche Monastery, the Himalayan Rescue Association clinic at Everest Base Camp, and the Icefall doctors of Sagarmatha Pollution Control Committee-SPCC.
Sasha Sak
Sasha Sak

- Over 100 ascents of Mt Elbrus
- Guides in Russia, on Kilimanjaro and on Aconcagua
- Is a fully trained, professional Russian/English translator
Sasha is an indispensable part of many of our CTSS programs. She is a Mt Elbrus and Kilimanjaro specialist but has recently expanded her repertoire to other regions of the globe including Aconcagua. Sasha has amassed well over 100 ascents of Mt Elbrus over the years and is one of the most respected guides on the mountain. Sasha got her Avalanche 2 certification in the United States and her Wilderness First Responder certification in Sweden.
All of our clients love Sasha and she has become one of our most popular and sought-after guides. She is incredibly strong, competent, and skilled while being incredibly caring and helpful to each and every one of our clients. I know of few climbers that have gone home not thinking of Sasha as a friend for life.
Sasha is originally from the Ural Mountains in Russia where she grew up fashioning her own climbing gear out of household items and challenging herself in the surrounding hills. She studied as a translator at St Petersburg State University before deciding that she loved the mountains more and becoming a full-time mountain guide. Sasha has never looked back and is incredibly passionate about her job.
When not guiding, Sasha would like to be nowhere else more than water skiing in Washington State or ice climbing in Ouray, Colorado! If you climb Elbrus or Kilimanjaro with us you will most likely have Sasha as a guide.
