I had the opportunity to meet Shiva about two weeks ago when we started our 5 day journey from Kathmandu to Poon Hill. In the process, I didn't just get to know Shiva the guide, but also Shiva the person.  It was obvious Shiva knew the mountains as seen by his knowledge of the terrain, his physical shape and the fact that he's been to Everest base camp over 50 times and is not even 30 years old.   Shiva is honest, friendly, personable and funny.  He listens well and will go out of your way to ensure that your needs are met, albeit the direction you'd like to take on the hike, the type of food you'd like to eat and the tea house you'd prefer.  I highly recommend him and plan on hiking with him again next year.
