David Gilligan
Senior Instructor

David Gilligan is a Senior Instructor at the Rule of Five Wilderness Company. David is a naturalist, a wilderness traveler, a writer and a professor. His work and personal interests have taken him to wild places all over the globe. For the last 20 years he has spent at least 100 days per year in the field, living in the open and sleeping on the ground.

He has taught natural history courses and led wilderness expeditions for Sterling College, Prescott College, and the Sierra Institute. His books include The Secret Sierra, Rise of the Ranges of Light, In the Years of the Mountains and Nature, Culture, Consciousness.

After beginning his studies in philosophy and religion at Flagler College in Northeastern Florida, he left for a few years to travel the continent and experience the diverse landscapes it offers. He resumed his studies at Prescott College in Arizona, where he studied natural history and ecology as both an undergraduate and a graduate student.

After a few years of working seasonally in the outdoors, David returned to Prescott College as a faculty member in the Environmental Studies and Adventure Education programs from 1999-2005. During this time, he explored the backcountry of the Sierra Nevada mountains in California and later other high mountains of the world, including the Icefield ranges of the Alaska-Yukon border country, the Highlands of Scotland, the Norwegian mountains, the Swiss Alps, the Nepal Himalaya and the Southern Alps of New Zealand.

Currently, David divides his time between his cabin in Vermont and the wild of the American West.

“There is a reason it feels good to be out in the natural world, paying attention to plants and animals, getting to know their life histories and the greater ecological systems they (and we) are enmeshed in. The practice of the naturalist: observation, description and interpretation of the natural world, is, essentially, the practice of being human. Our ancestors engaged in this same practice a million years ago and over the course of millennia it shaped and defined who we are. Every time we go out into the field and run our fingers over the surface of a leaf, catch the movement of an animal in our peripheral vision, note a change of light coming through the forest canopy or a shift in the feel of the air as the weather changes, we are living to our fullest potential.” – David Gilligan

Dusty Wessels
Adventure Motorcycle
Off-Road Instructor and Guide

Dusty Wessels co-founded West 38 Moto after logging over 200,000 miles on a wide array of big-bike Dual Sport and Adventure motorcycles over the last 10 years. As lead instructor and program developer, Dusty not only offers participants essential training, but experiences that go well beyond the typical paths well traveled.

West 38 Moto offers participants everything from foundational riding skills to ultra-advanced riding techniques. All this training is only amplified by Dusty’s infectious personality and energetic spirit. More important to Dusty than just riding is…riding with others. So engaging in end of day fireside chats are to be expected.

Having grown up with a Colorado-born can-do adventure spirit, Dusty can still be found fly-fishing across the west, backpacking through tree-lined forests, camping off his bike, or riding the remote deserts of Baja, New Mexico, Arizona, and California.

After serving in the Navy and a marketing and sales career in the adventure sport industry, Dusty re-discovered his passion for adventure by motorcycle. With numerous BDRs under his belt, thousands of hours and miles riding, camping, training, and exploring, he has found a natural fit in the adventure touring industry.

Present collaborations with industry professionals and companies seeking his advice and knowledge include Sena, Mosko Moto, Black Dog Cycle Works, BMW, and ADV Moto Magazine.

At Ro5 we know a quality practitioner is hard to find, but one with values, passion, and energy such as Dusty Wessels is a rarity. A credit to our industry and as a true expert of his craft, we are pleased to have him as part of the Ro5 Team!

Paul Ernsdorff
Adventure Motorcycle
Off-Road Instructor and Guide

As the co-founder of West 38 Moto, Paul Ernsdorff brings his long-time passion and involvement with wild explorations and motorcycles to experience the “paths less traveled.” In addition to offering trainings in the technical skills needed to ride these big bikes off-road, Paul and the West 38 Moto team “create experiences that impart the true essence of the Adventurer’s lifestyle.”

Paul’s can-do adventurous spirit can be tracked back to his teenage years, where he started riding a Kawasaki 750 turbo. Taking a short break from the 750 turbo and realizing turbos should not be on motorcycles, he shifted focus to sport-touring and adventure motorcycles. This was to pursue his interest of camping in remote places on motorcycles. This helped offset his 27-year career of being a software designer and developer.

Because of Paul’s lengthy career as a tech guy, he has insight and an uncanny ability to not only understand the why behind the how, but to communicate the information to others clearly. Paul is able to break down complex situations into manageable parts, which is what makes him a great trainer with excellent participant success.

In addition to West 38 Moto collaborating with industry professionals, Paul can often be found riding throughout the west on his 1200 BMW GS Adventure imparting the secrets of adventure riding. Paul’s commitment to others is steadfast; he expands participants’ horizons through adventure motorcycle riding.

As a practitioner of his craft, and a credit to our industry, we are excited for Paul to be part of the Ro5 team, bringing his expertise, experience, and talents to the trainings.
