Mike Hamill is the owner and founder of Climbing the Seven Summits and is one of the world’s premier high-altitude guides and expedition leaders. Mike has led more climbers to the summits of 8000m peaks including Everest than any other guide- 200+ summits on 31 X 8000m expeditions with an unparalleled success rate.

Mike began his climbing career on the steep rock and ice of New England and New York state. He hails from Hanover, New Hampshire but currently splits time between Seattle and Sydney, Australia.

Mike has been guiding for two decades and is a veteran of well over 120 major high altitude expeditions including 13 to Mt Everest, 11 to Cho Oyu, Manaslu, Shishapangma, the South Pole, Vinson, Denali, Putha Huinchuli, and Ama Dablam, 50 ascents of Mt. Rainier to name just a few. He has summited Mt Everest 6 times, lapped the famed Seven Summits 6 times, and climbed 2 X 8000m peaks (Shishapangma & Cho Oyu) in 8 days, one of only a few people in history to do so.

In 2012, Mike released “Climbing the Seven Summits,” the definitive guide book to the Seven Summits, with The Mountaineers Books. Mike was on Discovery Channel’s “Everest Beyond the Limits” in 2009 and has written for such publications as The Wallstreet Journal and Rock and Ice magazine.

Mike started the Tiger of the Snows Fund, a US based 501(c)(3) non-profit, in 2015 and remains Executive Director of the Fund. The mission statement of the Fund is to facilitate education for outdoor tourism workers and their families in underserved communities. A portion of all proceeds from CTSS goes to the TOTS Fund and each year Mike organizes a fundraising climb of Mt Rainier to benefit the TOTS Fund.

Mike was compelled to start CTSS because of his love for sharing the mountains and his knowledge of them.
