Jean-Mi Sarrazin

Jean-Mi Sarrazin – Owner, Technical Director/Designer

Born in the Southern Alps of France, Jean-Mi’s childhood was filled with mountain sports including downhill and backcountry skiing, rock climbing, hiking, spelunking, ice climbing and fly fishing. In his twenties, Jean-Mi followed his passion and became first a nationally ranked caving instructor and then a rescue worker with the French Spelunking Federation. In this time, he perfected his ropes skills, studied human psychology in order to be able to best help beginning climbers to overcome their own fears and stresses, learned advanced first aid and rescue skills and was then chosen to be part of the French Spelunking Rescue Team. For twelve years, Jean-mi served with this nationally recognized group of trained spelunkers who intervene in emergency climbing and caving situations in France and throughout Europe. In 1995, a group of Jean-Mi’s childhood friends had the idea of creating a suspended ropes park in the forest of the Queyras National Park. They asked Jean-Mi to join them and the aerial adventure park was born!

When Jean-Mi first arrived in the United States in 2007, adventure parks were still in their incubation stage. Since then, Jean-Mi has enjoyed not only helped to introduce and develop the aerial adventure park industry in the United States but has also recently loved adding treehouse and netted structures to his projects. He is very excited for the opportunity to keep bringing new concepts to future projects.


Born and raised in Australia, Mike came to Canada in 2006, to immerse himself in the Zipline and challenge course industry. He began with the construction of aerial parks followed by the management and operation of four very successful canopy tour parks. Mike started his own company, Aerial Parks, in 2010. He is heavily involved within our industry focusing on third party inspections, all operational / rescue training and high rope safety aspects for both operational and construction / rigging purposes ensuring that all are well versed working at height. His safety and construction / rigging skills have been utilized at many globally recognized sites such as Slotzilla Fremont Street Las Vegas, Fly LINQ Las Vegas, Niagara Falls, Nepal (World’s Steepest Zipline), Toronto Zoo, Mount Rushmore, Tanzania, Iraq plus plenty of Vail Mountain Resort locations. He occasionally assists Doppelmayer and Leitner-Poma with chair lift installations. Mike’s commitment to safety and the overall success for every business he assists is evident in his strong work ethic and his passion for the industry.
