Mike Hamill

Director and Lead Guide of Climbing The Seven Summits

Mike Hamill is a 6-time Everest summiter, world class mountain guide, and author. He oversees every CTSS expedition.

A veteran climber, Mike has built his vast experience over twenty years as a senior mountain guide across all seven continents. Known as the foremost expert, he authored the book “Climbing the Seven Summits” and has made 6 laps of the acclaimed Seven Summits mountaineering challenge. In 2008 he completes the circuit in just over 200 days.

Expeditions under Mike Hamill’s guidance have maintained a 91% expedition success rate overall with an 80% client success rate on all expeditions.

An adventurer by nature, Mike has skied to the South Pole, cycled unsupported across the United States, competed at a national level as a nordic skier and is an ultramarthoner, cyclist, traveler and philanthropist. He began his climbing career on the steep rock and ice of New England and New York State while obtaining a bachelor of science from St. Lawrence University in Canton, New York. He is originally from Hanover, New Hampshire, and Bridgton, Maine.

His love for the mountains and adventure continues to compel him to travel the globe and connect with the local mountain communities, particularly the Sherpa of the Khumbu region. This bond was his impetus in creating the “Tiger of the Snows Fund” a not-for-profit that provides grants to further education of mountain tourism workers and their families.

Mike is a familiar and well respected face in the mountaineering community. He is passionate about imparting his knowledge, skills and experience to inspire others to harness their full potential in the mountains.
