Mountain Professionals

The company itself was founded by outdoor professionals and guides with decades of experience leading adventures around the world. Mountain Professionals has guided successful expeditions on many of the world's great mountains since 2005. The guiding and logistics network that built Mountain Professionals includes veteran staff that have spent a lifetime pursuing safe and successful adventures around the world.

Mountain Professionals LLC was a simple idea in 2000. This was the year that Ryan Waters and Dave Elmore met in South America, where both were working in the industry and both had the idea to start their own guiding company. As the guiding season progressed, so did the business plan. Culminating on an Aconcagua climb, which they call the "highest business meeting ever."

Over the course of the guiding season, Dave and Ryan spoke of their vision for an international guiding company which embraced their outdoor educational background, risk management skills, client care awareness and desire to deliver safe high-quality expeditions. Mountain Professionals was founded in 2005.
