In loving memory of Mike Gardner (1991 – 2024)

Michael Gardner was raised by mountains. He was a second-generation mountain guide who spent his childhood in the Teton Range in Wyoming, the San Juans in Southwest Colorado, and the Himalayas. Michael’s life was undoubtedly shaped by time spent in the mountains.

His guiding apprenticeship began informally at age eight under the tutelage of his father and led him to become one of the youngest guides in the U.S. In addition to his lifelong relationship with guiding and climbing, Michael was a professional skier on the World Tour circuit for many years, and in 2014, he received his bachelor’s degree in Education.

Michael was continually drawn to the wildest reaches of the planet—from Antarctica to Alaska and the Himalayas. For Michael, being in the mountains was more than just a profession; it was a lifestyle. He found inspiration in pursuing his own alpine objectives on some of the wildest peaks in the world, and his legacy leaves behind multiple first ascents and ski descents across Alaska, the Himalayas, and the Western U.S.

Michael will be deeply missed and remembered by the Climbing the Seven Summits team.

Ossy is one of our Mt Everest, Mount Vinson and Aconcagua specialists.

Ossy was born and raised in Ecuador and knows his country’s peaks intimately. He has climbed Pik Lenin, the difficult West Face of Huayna Potosi, Pumori, Aconcagua’s South Face, the Dolomites, and throughout South America, the Cassin Ridge on Denali among many other routes.

Ossy is a fully internationally certified IFMGA guide.

Sydney is a Colorado native, so naturally, she has been in love with skiing since she was 3-years-old.

At 18 she started her guiding career as a raft guide in the front range of the Rockies and became enamored with working in the outdoors.

For years she honed her backcountry skills skiing and climbing in France, Chile, Colorado, and Tahoe, and she is so happy to be able to share her love for human-powered adventures with others.

Sydney has worked at Squaw Valley on Ski Patrol for 4 seasons and guiding was a natural progression. Recently, she was accepted to the AMGA’s Ski Guide track. Once the skiing dries up in the summers, you can find Sydney guiding trips on Mount Shasta and working in the Tahoe basin.

Tomas was born in Patagonia, Argentina and at an early age as became a climber in the Nahuel Huapi National Park.

He is a certified Mountain Guide from the EPGAMT and a member of the Argentinean Mountain Guides Associations (AAGM) and has extensive experience leading expeditions on Mt. Aconcagua, which he has repeatedly ascended, as well as on other peaks in the Central Andes, Patagonia, Pakistan, Chile, Peru, Bolivia, Antarctica including 14 expeditions to Vinson and in the Himalayas in Nepal. During the winter season, he guides backcountry skiing, mostly on the volcanoes in Patagonia. He feels very privileged to work as a mountain guide and to be able to share experiences with people that have the same passion. He lives in Buenos Aires, Argentina.
