He is trained in eco tourism, Leave No Trace techniques, and holds his Wilderness First Responder certification. Besides his obvious interests in trekking, mountain and ice climbing, he also enjoys mountain biking and horseback riding. With his first forays into rock climbing school in the central Chilean Andes, Jaime began to explore its mountains and interpret its geography, getting to spend more time in the outdoors in the city. He is a devoted lover of nature and mountains and enjoys using each field trip as a new opportunity and space for meditation.


Guillermo (Willie) Benegas

Willie spent his youth climbing in Northeast Patagonia with his father and twin brother, Damian. This served as a strong background for a developing climbing career, which took off when he and Damian moved to the States at age 21. They headed straight for the big walls of Yosemite, where in the years to follow they made over 40 ascents of El Capitan. Each year Willie has returned to Argentina to guide trips on Aconcagua, a mountain which he has climbed over 50 times. These ascents include the difficult South face, and a speed record which held for five years. In 1995, he made an impressive first ascent of the North face of Trango Tower in Pakistan. He has since led over 20 Himalayan expeditions, including nine Everest summits, Cho Oyu, Ama Dablam, an attempt on the North face of Jannu, and a new route on Nuptse, dubbed The Crystal Snake, which earned him and Damian the prestigious Golden Piton Award. Willie has also set speed records in Africa on Mt. Kilimanjaro and Mt. Kenya, with his brother has made three attempts on the highly coveted Pakistani peak Latok 1 and has done first ascents on the big walls of Baffin Island. Having also climbed dozens of Bolivian and Peruvian peaks, he has earned a place among the elite in the world of high altitude alpinism.

Nicholas Malik

Ask Nick what he’s thinking about and you’ll get an answer somewhere between bacon, skiing, and climbing. What might be lacking in his range of thoughts, he surely makes up for with his deep and loving admiration for the outdoors. Going for weekend camping trips with the family growing up, Nick caught the bug for the mountains in California’s Sierra Nevada range (and occasionally a few fish). Later, he attended the Colorado Rocky Mountain School where he furthered his knowledge of the mountains and learned to climb and telemark ski. College brought him to the rugged San Juan Mountains and blazing desert of the Southwest where he completed a BS in Cellular & Molecular Biology.  Nick has climbed extensively in Southeast Utah and the Teton Range developing a soft spot for Wingate sandstone.  He now calls the PNW home, and with his AIARE Level 2, Wilderness First Responder, and LNT Master certificate, he’s ready to give you the experience of a lifetime!

Gary Newmeyer

Gary started his climbing career while enlisted in the US Navy in Washington State, swapping shoes with his roommate and doing a little bouldering. Before taking his climbing to the next level, he first had to do a 7-month deployment in the Middle East. Bitten by the climbing bug, he learned as much as possible without being able to touch rocks. Knots and hitches during down-time at work, self-rescue and anchor systems from the bunk beds in his room, and reading climbing books before bed. This turned out to be a great way to get a solid foundation with which to expand on. After serving, Gary moved to the land of sunshine in beautiful Durango, Colorado. He has since then became an AMGA Certified Single Pitch Instructor, AMGA Apprentice Rock Guide, and an AMGA Apprentice Alpine Guide. Gary has also completed an AIARE Level 2 Avalanche Course and is a Wilderness First Responder. Gary loves climbing the sandstone cracks of the desert. Get in touch to climb in the Southwest region with Gary today!

Lyra Pierotti

Lyra had her first view of the mountains on hikes atop the shoulders of the Tahoe Summer Music Festival's tuba player, back when she weighed less than a tuba. This exposure led her to study ecology and pursue rock climbing.  While studying at UC San Diego, she worked as a guide for her university’s outdoor program. She led rock climbing, backpacking, and sea kayaking trips, and also taught field ecology for several San Diego-based outdoor education programs.  Lyra spent a year living in the French Alps, studying geology, climbing, and skiing. Shortly after her return, pining for more mountain adventures, she relocated to the Eastern Sierra. Dropping plans of going back for a masters degree in ecology, she started guiding on Mount Shasta in the summers – and was thus hopelessly hooked. She has since guided rock, ice, and alpine climbs in Yosemite and all over the Sierra, and teaches avalanche courses. Lyra’s international guiding trips include successful trips on Aconcagua and Mexico’s volcanoes, as well as obscure mountaineering adventures in Baja, and trekking in Italy’s Dolomites. Lyra is an AMGA Certified Rock Guide, an AIARE Level 1 avalanche instructor, and holds a Wilderness First Responder.

After several years working as a Physician’s Assistant in Native Alaskan villages and volunteering medical services around the world for African Zulu tribes, Haitian villages, and Amazonian natives, Thai has returned to the world of guiding. In 2007 he was the winter with the U.S. Antarctic program guiding various science groups around the frozen continent. He has guiding experience in Nepal, the Andes, Denali, New Zealand, and the Cascades. Fluent in Spanish and with a degree in Latin American studies, he has a wealth of knowledge to share about the Andean communities.


Tino Villanueva

Tino is a northwest native and calls the Cascade Mountain Range his home. These days he embraces his status as a citizen of the world, regularly splitting time between South America, Asia, Europe, Alaska and Washington, climbing and skiing his way the world round. Tino enjoys all facets of climbing and is equally proficient on rock, snow, ice or skis, having accomplished first climbing ascents and ski descents in the Cascades, Alaska and the Himalaya. Aside from working as a Mountain Guide for the better part of a decade, Tino has worked as an avalanche forecaster, snow safety expert and professional ski patroller. He is also a heli-ski guide and an Athlete/Ambassador for Helly Hansen. Depending on the season, given a free moment you will find him cruising splitter cracks in the mountains or on the hunt for pockets of fresh powder in the most unlikely places. Tino truly enjoys sharing his time in the mountains, and his knowledge of them, with others. Tino holds a Bachelor of Science in Human Physiology from the University of Oregon. In 2013 Tino was awarded the Lyman Spitzer Cutting-Edge Climbing Award for his climbing achievements in Nepal. He is a Wilderness First Responder, Outdoor Emergency Care provider, AIARE Level 3 Avalanche certified, AIARE Certified Level 1 and 2 Course Leader, a Leave No Trace Trainer and is pursuing IFMGA/UIAGM certification as an active member of the AMGA.


Pavel Vorobyev

Pavel holds the coveted "Snow Leopard" award, which is earned from completing ascents of all five of the former Soviet Union's 7,000 meter peaks. When not guiding or skiing, he is busy working as the Technical Director of the Kyrgyz Association of Mountain Guides. In addition to many trips up Mount Elbrus and in the Pamirs, he has climbed on Nanga Parbat in the Karakoram and can be found heli-ski guiding.


Andrew Wexler

Andrew grew up the son of a textile salesman, far, far away from the nearest mountain. As fate would have it, he now finds himself living in the heart of the Canadian Rockies, guiding, climbing and skiing year round. When not climbing or skiing, Andrew can usually be found skiing or climbing. This monotony of character may have a myriad of drawbacks, but it has also seen him to the top of classic routes and peaks including Fitzroy, Ama Dablam, El Cap, Denali’s Cassin Ridge and Huayna Potosi’s West Face. Along with Mountain Madness co-workers Dylan Taylor and Joe Stock, Andrew has also spent what may be considered a ridiculous amount of time skiing across various ranges in Alaska. It is a rare occurrence to catch Andrew outside without his camera, and his photos and words have appeared in numerous national and international publications. He is a fully certified ACMG/IFMGA Mountain Guide.


Deana Zabaldo

Deana has lived and worked in Nepal for over six years and has traveled in more than 25 countries. With a journal and a pair of boots, she has explored Asia from its rice paddies to its mountaintop temples, including Tibet, Bhutan and Mongolia. More important than adding stamps to her passport are the friendships she builds with landless farmers, wealthy factory owners, sari-clad women, and hermit monks. She has an experienced eye for Buddhist art, a taste for local cuisine, and a keen interest in ancient traditions. Deana's first encounter with the Himalayas was as a Peace Corps Volunteer in a remote mountain village three days walk from the nearest road. Far from hot showers and internet connections, she used her hands both to eat rice and build classrooms. Later in San Francisco, she went on to direct cultural exchange programs and run a marathon. Charmed by Nepal (despite the lack of amenities), Deana returned to advise businesses and non-profits, teach yoga, and guide treks. Currently when she's not guiding, she is creating a sustainable artisan business in San Francisco and starting an orphanage outside Kathmandu. Deana is fluent in Nepali, holds a Wilderness First Responder certification, and will brew you the best coffee in the Himalayas! Moved by the spiritual and cultural vibrancy of the region, she's full of stories about Tantric goddesses, the Maoist insurgency, royal massacres, arranged marriages, secret explorations, and the realities of Shangri-La.

 “What would a guide be without someone to lead? Good weather, bad weather, easy, difficult, I need to sing the same tune. That was the gift of our mountains. Climbing to the summit one does his job, another is on vacation and the luxury of their efforts is friendship.” – Gaston Rebuffat, famous French guide
