Zach Vanderwall

Zach’s first Wilderness Medical Associates course was in Red Lodge, MT for a WEMT Upgrade in 2004. Those five days of training quickly put his previous three years of volunteer EMT work in perspective and prompted his decision to become a WMA instructor. He called Seattle home for 19 years, and the geography of the Pacific Northwest allowed him to hone his outdoor skills in the surrounding mountains, rock, and rivers. Zach’s pursuit of adventure has led him to various hot spots beyond the Northwest; including Cascade volcanoes, Bugaboo rock, and Mountains in Peru. He spent 10 years working at a camp and hosting college programs, which exposed him to guiding and instructing in an Experiential Education format. For 11 years, Zach has been an EMT utilizing his skills in rural settings, SWAT situations, movie sets, and even occasionally, as a father of thee boys! He enjoys living in western Montana with his wife and kids, where he divides his time between building houses and traveling to different venues as an instructor.

Toby has also worked with Outward Bound as a dog sledding guide, getting to be on trail with dogs for the past four winters has only increased his connection to the wilderness.
