A San Antonio Pilates instructor who traded a decade-old dream for the high peaks, and found her family among the mountains of Nepal and Pakistan.
Those who knew Sarah Mallory Geis describe her the same way, again and again: a bright light. She was the kind of person whose energy filled a room before she said a word, the friend who turned a Nintendo afternoon into a lifelong bond, the client who became so devoted to helping others feel strong in their own bodies that she built a business around it.
She was 39 years old, a proud daughter of San Antonio, Texas, and a woman who spent her final years chasing something she had only recently discovered in herself: a love for the mountains.
Geis died on July 30, 2026, in an avalanche on Broad Peak, the world’s twelfth-highest mountain, in Pakistan’s Karakoram range. She was one of ten climbers lost that day.
But to understand her only through that loss is to miss almost everything about who she was. This is a story about a woman who built a life at home, then had the courage to leave it behind to build another one, higher up.
A Life Built at Home
Long before Broad Peak, before crampons and high camps, Sarah Mallory Geis’s world was San Antonio. She worked alongside her father, George Geis, in the family’s real estate business, and for more than a decade she ran her own Pilates studio in the city. Owning that studio, and helping her clients feel good in their own bodies, had been a dream of hers since long before she opened the doors a dream she had held onto for more than ten years before it became real.
She gave her time to the wider community too, serving as a former board member of San Antonio Sports, an organization devoted to youth fitness and to bringing major sporting events to the city. The organization would later remember her for her “bold spirit, generosity, and commitment.”
Friends and family describe a woman who was positive, smart, ambitious, and a natural athlete, with a deep love of travel, hiking, and the outdoors.
Her lifelong best friend, Caitlyn Anthony, remembers a childhood built on the small, ordinary joys of growing up together playing Nintendo and Mario Kart, watching movies, sharing Happy Meals a friendship that matured, in time, into shared adventures, including a 2021 hike up Angel’s Landing in Utah. Geis carried a camera everywhere she went, too, building a following as a travel photographer with a restless eye for a good view.
But somewhere along the way, running her studio, coaching her clients, building her business, Sarah Mallory Geis began to change. And she let herself notice it.
The Leap of Faith
In February 2026, she closed the Pilates studio she had spent more than a decade building. She explained the decision to her followers on Instagram in words that have since become some of the most quoted of her life:
“Saying goodbye to a big chapter to make room for new magic… Owning a studio and helping people feel good in their bodies was a dream that started over a decade ago. It’s been an incredible journey and I’m so thankful to everyone who supported me during this chapter.”
She admitted the decision had taken over a year to make. A “nagging feeling that life has bigger plans for me” kept surfacing, she wrote, and for a long time she resisted it, afraid that walking away from something she had worked so hard to build would make her selfish, or a failure. But she had reached a simple, hard-won conclusion about herself:
“The truth is I’m not the same person I was when I started this venture. We are allowed to change and grow, and have our dreams evolve along with us.”
With her last client sessions wrapped up, she joked that she now had just one remaining client to train for the foreseeable future: herself, whom she called “incredibly high maintenance.” And she named, with startling clarity, exactly where she suspected this new chapter was headed:
“So here we go. Taking a giant leap of faith into the unknown to see where life goes. I have a sneaking suspicion there will be lots of helmets, harnesses, and crampons involved.”
It takes a particular kind of courage to walk away from something you built with your own hands, especially when it was once your dream. Geis had that courage. She was ready to become someone new, even if it meant starting over.
Finding the Mountains
Her interest in mountaineering was, by outdoor-world standards, a recent development. Friends say she began focusing seriously on it about three years before Broad Peak, filling that time with training, multi-day trips, and expeditions further and further from home.
In January 2026 she joined a women’s ice-climbing weekend in Colorado, still relatively new to the discipline, where fellow climber Kimberly Hardman remembered her as a natural athlete who already carried real mountaineering experience from Nepal, and who respected the mountains and the risks they carried.
That experience included summits of Lobuche East, at roughly 20,075 feet, and Mera Peak, both in Nepal’s Khumbu region near Everest Base Camp serious high-altitude climbs, even if still short of the 8,000-meter mark. It was on Mera Peak that she formed one of the defining friendships of her climbing life, with Pakistani guide Sohail Sakhi, who had led her on that mountain and who would later guide her on Broad Peak as well.
Geis told the story of that Mera Peak climb herself, in a post that captures her sense of humor and her willingness to trust her own body. The plan had been a standard one: reach high camp from the village of Khare, rest, then push for the summit overnight. But the weather had been unpredictable, and when a clear window opened, Sakhi had another idea.
“About halfway up to high camp, I get that look from @sohailsakhii that means one thing: he’s plotting… What if we go in one push and try for the summit for sunset? My initial reaction was ya, I think only the professionals like him and our guide can do that. But he was right, I did feel great and there’s only one way to find out what my body can do, so why not try?”
They climbed 1,500 meters, about 5,000 feet, in seven hours, and reached the summit for what Geis called the most spectacular sunset, with the mountain entirely to themselves. Looking back on it, she gave the credit to her friend and guide:
“Oh you guys are sickos,” she said with a giant grin — “grateful to my friend and fellow sicko @sohailsakhii for seeing more in my abilities than I do myself most days.”
That was Sarah Mallory Geis in the mountains: bold enough to say yes to the harder, riskier plan, but never blind to it. Those who climbed alongside her were consistent on this point she was not reckless. She trained deliberately, she listened to guides she trusted, and she understood exactly what she was choosing to risk each time she went higher.
The Big Objective
Broad Peak, at roughly 8,047 to 8,051 meters, or about 26,400 feet, would be her first attempt at an 8,000-meter mountain one of only fourteen such peaks in the world, and her first major expedition in Pakistan.
In mid-June 2026, she posted about a new pair of boots bought for the trip, describing it in her own words as her “first big kid climbing expedition,” and hoping, as she put it, to get “this body and these boots up Broad Peak, the 12th highest mountain in the world.”
She traveled with the Pakistani outfitter Moving Mountains, joining a larger ten-person international team from different operators that included the renowned Nepali mountaineer Nirmal “Nims” Purja, Omani climber Nadhira Al Harthy, Chinese climber Wang Zhong, and Nepali climbers and guides including Pur Bahadur “Yukta” Gurung and four others Sherpas.
Once again, Sohail Sakhi was by her side as her guide, the same partner who had shared that sunset summit on Mera Peak.
Before she ever reached the mountain itself, Geis paused to take in the journey there. Climbers and expedition teams typically fly or drive into the town of Skardu from Islamabad, where they complete government paperwork, attend briefings with the tourism ministry, and finish their final gear checks before a six-to-seven-hour jeep drive to Broad Peak base camp. Somewhere along that road, Geis stopped to write about what she was seeing.
“The scale and beauty of Skardu is hard to grasp, even in person. This view was worth every step.”
It reads now like a farewell, though of course she did not intend it that way. For Geis, Broad Peak was simply the natural next step in a passion she had already invested three years of training, travel, and trust into. She was not new to the mountains. She was ready for a bigger one.
The Mountain and the Loss
On July 30, 2026, an avalanche struck the team as they climbed between Camp 2 and Camp 3, at roughly 6,580 to 6,600 meters, around midday. Contact with base camp was lost. Search and rescue teams, including Pakistani authorities and the military, worked against difficult weather and terrain to reach the site. In the days that followed, it was confirmed that all ten members of the expedition had lost their lives, including Sarah Mallory Geis and her guide and friend, Sohail Sakhi.
Her family asked for privacy as they processed what they called an unimaginable loss, while focusing on bringing her home. In a statement, they said what so many who knew her had already been saying for years, in their own words:
“A bright light who was loved deeply by her family and friends. She will be profoundly missed.”
They said they were heartbroken not only for their own family but for all ten families touched by the avalanche that day, and expressed gratitude for the outpouring of support that followed.
What Remains
Her father, George Geis, remembered a daughter who was positive, smart, and capable of nearly anything she set her mind to, and who had made it clear that hiking and mountaineering were exactly what she wanted to do with her life.
Her lifelong best friend, Caitlyn Anthony, has been careful to insist that Sarah Mallory Geis was so much more than the way her story ended a woman whose ambition and drive inspired the people around her to go after the things they loved, too.
San Antonio Sports, where she had once served on the board, called her a dear friend who lived with extraordinary courage, curiosity, and a deep sense of adventure. They praised her bold spirit, her generosity, and her commitment to her community, and said they would remember her not only for the remarkable heights she reached, but for the energy and enthusiasm she shared with everyone fortunate enough to know her. The impact she made, they said, will never be forgotten.
Sarah Mallory Geis spent most of her life building something steady at home in San Antonio, a business, a community role, a decade of routine and purpose. Then, at 39, she allowed herself to want something else, and had the courage to say so out loud, boots and crampons and all. She found, in the mountains of Nepal and Pakistan, a friend in Sohail Sakhi who saw her potential before she fully saw it herself, and a version of herself she was only beginning to discover.
As of now Sarah Mallory Geis and her guide, Sohail Sakhi, went missing together on Broad Peak, the same mountain they had both worked so hard to reach she chasing her first 8,000-meter summit, he guiding her toward it just as he had on Mera Peak. They had trained for this, trusted each other for this, and in the end, the mountain took them together.
She did not get to see where that leap of faith would ultimately lead. But she got to feel it, fully, up to the very end on a sunset summit she was told only professionals could reach, and on a jeep road into Skardu, looking out at a view she called worth every step.
Our condolences go out to the Geis family, to Sohail’s family, and to the families of all ten climbers lost that day on Broad Peak to everyone who loved someone who never came home from the mountains they gave their lives to.
