Founder & Managing Director
Welcome to Alpinist Climber Expeditions.
At Alpinist Climber Expeditions we believe that extraordinary mountains deserve extraordinary leadership, and that belief is the reason ACE exists. When I founded the company in 2021, my vision was simple: to build a premium high-altitude expedition company rooted in professionalism, trust, and an uncompromising standard of safety, the one built on a genuine passion for high-altitude mountaineering, not just the pursuit of summits.
As a certified IFMGA Mountain Guide, I have spent years climbing and leading expeditions across the Himalaya and Karakoram, including on Everest, K2, Makalu, Dhaulagiri, Manaslu, Lhotse, and Ama Dablam. Every one of those mountains is different, but they've taught me the same lesson that a successful expedition is the result of teamwork, precise planning, sound judgment, and a strong commitment to the people who trust you with their journey.
That understanding shapes everything we do at ACE. We focus exclusively on quality over quantity, and we design each one with the same care, experienced leadership, personalized support, and logistics held to the highest international standard, from arrival to summit and safely home again. We keep our teams small so every guest receives the attention they deserve while ensuring sound decisions at every step.
Since our founding, we've had the privilege of guiding climbers, professional athletes, explorers, and adventurers from around the world - supporting first Himalayan summits, alpine-style ascents, 8,000-meter expeditions, and world-class speed and projects without supplemental oxygen. We've shared in personal milestones, national firsts, speed records, and historic ascents. Those achievements belong to the climbers who earned them, but they also speak to the strength, experience, and professionalism of the team standing behind them.
Our commitment doesn't end at the summit. It extends to responsible mountain practices, environmental respect, and a level of safety and service that defines every detail of the experience. Every climber who joins ACE becomes part of a team that values preparation, integrity, and relationships built to last well beyond a single expedition.
Whether your ambition is an iconic Himalayan peak or the challenge of an 8,000-meter giant, we are honored to be your trusted partner on that journey.
Thank you for considering Alpinist Climber Expeditions. I look forward to welcoming you to an exceptional mountain experience on your next great adventure.

Alpinist Climber Expeditions
Alpinist Climber Expeditions (ACE) was founded on a clear vision: to deliver premium, professionally led high-altitude expeditions built on uncompromising safety, world-class logistics, and expert mountain leadership. It was the first step on a journey that would soon reach the world's highest summits.
ACE welcomed its first international climbers, Christiane De Jong and Rogier van Keulen, on pioneering expeditions that laid the foundation for the company's growing international reputation.
Later that year, ACE organized the Himlung Himal Speed Project with Benedikt Böhm and Prakash Sherpa, setting a remarkable base-camp-to-summit record of 6 hours 35 minutes - a performance sponsored by DYNAFIT that showcased ACE's ability to manage elite high-altitude projects.
ACE successfully led an alpine-style expedition on Pumori and a summit of Nuptse with Christiane De Jong and Prakash Sherpa. In recognition of his achievement, Christiane De Jong received one of the Netherlands' highest alpine honors from the Dutch Alpine Club.
Later in the year, ACE managed the Cho Oyu Speed Project with Benedikt Böhm and Prakash Sherpa, completing base camp to summit in 12 hours 35 minutes, once again sponsored by DYNAFIT - another world-class high-altitude performance under ACE leadership.
ACE successfully led an Everest expedition without supplementary oxygen. During the climb, Lenka Poláčková became the 10th woman in history to summit Mount Everest without supplementary oxygen - a landmark moment for women's high-altitude mountaineering and a testament to ACE's expertise in supporting elite expedition goals.
In August, ACE organized the Spantik Speed Project, once again supporting Benedikt Böhm and Prakash Sherpa in another world-class alpine performance.
In spring 2025, ACE organized the Flash Everest Expedition, where Karel Abraham completed an extraordinary Czech-to-Czech Everest expedition in just 14 days - a feat made possible by exceptional planning and logistics led by Prakash Sherpa.
Later that season, ACE led a successful K2 expedition under the leadership of Prakash Sherpa, achieving two historic milestones: Kah Shin Leow became the first Singaporean to summit K2 without supplementary oxygen, and Lenka Poláčková became the first Slovak woman to summit K2 without supplementary oxygen.
After five years of growth, world-class expeditions, and historic achievements, Alpinist Climber Expeditions steps into a new chapter with a refreshed brand identity and logo.
This isn't just a visual change - it reflects who we've become. It carries the experience we've gained, the trust we've earned, and our ongoing commitment to raising the standard of premium high-altitude expeditions.
Our new identity is more than a new look. It's renewed ambition, continuous improvement, and an unwavering commitment to excellence.
2021-2025 was our foundation. 2026 marks the beginning of our next ascent. New Identity. Higher Standards. Greater Ambitions.
From our first alpine climbs in 2022 to world-class speed projects, summit records without supplemental oxygen, and historic ascents on Everest and K2, every milestone has shaped who we are today. ACE has grown into a standard high-altitude expedition company recognized for world-class logistics and expert mountain leadership.
Looking ahead, our vision stays clear: to combine international guiding standards with the unmatched expertise of a Nepal-based IFMGA Mountain Guide and an experienced local team - delivering professionally managed expeditions, personalized service, and exceptional mountain leadership to climbers from around the world.
Every summit tells a story. Let ACE help you write yours. Partner with our expert team for a premium, safety-first expedition experience - backed by a proven legacy of record-breaking ascents and world-class mountain leadership.

Beyond these landmark achievements, Alpinist Climber Expeditions has quietly built a legacy across Nepal, Pakistan, Tibet, and the wider Himalayan ranges. From technical alpine ascents and 6,000-8,000-meter expeditions to bespoke private climbs and elite speed projects, ACE has guided mountaineers from around the globe toward their personal summits - safely, and with purpose.
Our portfolio spans iconic peaks including Everest, K2, Cho Oyu, Himlung Himal, Pumori, Nuptse, Cholatse and Kyajo Ri, among many others across the region. Each expedition carries the same signature: expert leadership, meticulous planning, uncompromising safety, and a genuinely personalized approach to every climber we guide.
Today, ACE is recognized as a trusted, premium high-altitude expedition company - delivering world-class logistics and mountain leadership while supporting record-setting climbs, first ascents, speed projects, and life-changing Himalayan experiences.
Many expeditions rely on seasonal guides with limited experience or prioritize speed over skill.
Our IFMGA-certified guides are seasoned alpinists with decades in high-altitude terrain. We lead with quiet confidence and deep technical know-how, not ego or hype.
Guiding often begins and ends with logistics. There’s little focus on your personal journey or progress.
We coach, train, and challenge our climbers to grow mentally, physically, and technically. Every summit with us builds your skills, strength, and confidence.
Crowded routes, poor acclimatization, and environmental shortcuts are too often the norm.
We are Nepal’s first guiding company focused exclusively on alpine-style expeditions. With small teams, tailored pacing, and a respect for the mountain, we maintain world-class safety standards and a high summit rate, without compromising the environment.
Good news from the Khumbu Region. The weather at Ama Dablam Base Camp has improved since this morning, and the mountain is now clearly visible. Ama Dablam (6,812 m) is one of the most beautiful peaks in the Himalayas. After a few hours of changing weather, it was a great moment to see it clear and bright from camp. Weather can change fast in the Everest Region, so our team keeps checking the conditions through the day. Clear spells like this one help us plan with confidence and keep everyone safe. Take a look at the photos below to see the view from Base Camp today. Ama Dablam, clear and bright from Base Camp this morning. Planning a climb in the Himalayas?
