OUR TEAM
Dian Irnani
Co-Founder and Marketing Director
Dian is the head of marketing and direction and the main driver behind JTRACE SG. Since 2005, she has been involved in the outdoor education industry providing outdoor adventure sessions, programmes and treks for various companies in Singapore.
She has been an avid climber and trekker since 2007 and her expeditions have taken her to pretty wild places like the jungles of Malaysia, volcanoes of Indonesia, Himalayas in Nepal and the Alborz and Zagros mountains of Iran and Turkey. She has lead numerous expeditions to Everest Base Camp in Nepal, Mount Kilimanjaro in Tanzania and Mount Elbrus in Russia.
Stemming from her experience, Dian decided to launch JTRACE SG as a co-founder to provide outdoor education and adventures to people in the region and share her passion through these means.
When not leading outdoor programmes and treks in Singapore or abroad, she enjoys kayaking, trekking and rock-climbing and spending family time as a mother and wife.
Jeremy Tong
Co-Founder & Chief Adventure Consultant
Jeremy Tong is a Singaporean mountaineer, educator and keynote speaker who turned high-altitude experience into practical leadership and resilience training. He co-founded JTRACE in 2018 to translate lessons learned on high-altitude expeditions into bespoke mountaineering programs, corporate training and outdoor education programs across Southeast Asia. His professional page can be seen here.
Jeremy has almost 2 decades of high-altitude expeditionary leadership experience, 10 years as an Outdoor Education Specialist in United World College South East Asia and is one of Singapore’s best known mountaineers. His expedition résumé span climbs across the world — including Mount Everest and 6/7 Summits of the World, which he uses as real-world case studies for expedition planning, risk management and leadership under pressure. His Mount Everest ascent is well documented by Channel NewsAsia here.
Jeremy’s work in outdoor education and community impact has been recognised locally: he was a recipient of the Singapore Silent Heroes award in 2019 and the Nanyang Outstanding Young Alumni award in 2020 for raising S$25,000 for the Singapore Cancer Society and Children's Cancer Foundation.
A frequent speaker and educator, Jeremy has been invited by academic and professional organisations to share his keynote, Dare To Climb: Building the “EVEREST” mindset — translating mountaineering practices into frameworks for resilience, teamwork and decision making in volatile and complex environments. His profile and outreach work are well documented in NTU/NIE features and Singapore media.
At JTRACE, Jeremy leads a team of certified expedition leaders and instructors to deliver practical, safely run programs — from basic mountaineering courses to experiential programs and hypoxic training — aimed at developing capable, confident climbers and future mountain leaders.
Mohammad Irfan
Expedition Leader
Irfan is an expedition leader whose idea of fun involves long days uphill, thin air, and the occasional questionable life choice in pursuit of a summit.
Having climbed across nine countries, from the volcanoes and jungles of Southeast Asia, mesmerizing beauty of Kyrgyztan to the icy slopes of Mount Elbrus and the trails of the Himalayas, he believes every mountain offers a lesson far greater than the view from the top.
Back home in Singapore, Irfan also leads basic survival courses, helping people build confidence, resilience, and practical outdoor skills beyond their comfort zones.
In 2025, he led Kyrgyzstan Basic Mountaineering Course and Mount Elbrus Expedition, supporting climbers beyond their perceived limits. Known for balancing adventure with humour and heart, he is passionate about creating meaningful experiences and proving that growth often begins where comfort ends.
