On July 27, 2014, my birthday, I became the oldest American to summit K2. The professionalism and skill of Garrett Madison was key in this achievement. His attention to detail, plus leveraging his extensive Everest experience gave our team the best chance to summit and descend safely and quickly on arguably the world’s toughest mountain.

Climbing Kilimanjaro was my first big mountain adventure. I had no idea how much fun and how rewarding it would be. All of the logistical details were handled by Garrett Madison and the program seemed very streamlined and well thought out. For climbers wanting a great program on Kilimanjaro I strongly recommend going with Garrett.

The expedition was everything and more. The summit was great, but the team was the bonus — Garrett, man we got on so well. That made K2 for me. You selected well and were the perfect leader allowing us to be the mountaineers we are. Words won’t express my gratitude in the overall expedition.

I’ve been very fortunate to have Garrett Madison as my guide on five high altitude climbs. As one of the top mountain guides in the world, Garrett possesses extraordinary expertise, athleticism, and passion for climbing. He not only keeps his clients safe, he ensures that they have a truly unforgettable and fun experience.

Thank you Garrett Madison for taking my family and I on an unforgettable adventure to Africa! We wanted to climb Kilimanjaro and do a safari, but most of us had little or no hiking experience, nor had we traveled much outside of the US. The experience greatly exceeded our expectations, and changed our lives forever.

I had a magnificent time in Africa with Garrett Madison. Everything was first class. Garrett puts his climbers, at all times, first. Garrett always made sure I was taken care of. It was a fantastic experience.

Thank you for a journey of a lifetime Garrett. I had an absolute blast and I can finally say I climbed with Madison Mountaineering. THE ONLY WAY TO GO ????

I’ve had the great fortune of climbing with Garrett on several expeditions. He is, quite frankly, the ultimate guide. His knowledge, skill set, temperament, and judgement are unparalleled. Safety is key. After all, climbs only count if they are round trip. And he makes it fun! I can’t imagine climbing without him.

Garrett / Madison Mountaineering is the most professional, organized, flexible and creative guide services I have used. The preparation and dissemination of detail prior to climbs is exemplary, knowledge imparted while in the mountains superb, and memories created from these trips irreplaceable.
