I met Birendra when I moved to Kathmandu, and he offered to arrange my trip to Everest Base Camp. It was a great experience all around - he is very willing to modify your itinerary to suit your needs, and runs a very professional and trustworthy company. He really cares that you have a great experience visiting his country, and I would highly recommend hiring him and his team! Our guide for the trek was Sonam, and he was excellent - very friendly and funny guy, and he made sure we were always comfortable. He was willing to change the pace to suit us as we wanted to either push a bit harder or take it easier.
