Michele Johnson, Interim Executive Director

A West-side Detroit Street that ended with a cul de sac and a 30 acre park provided endless exploration for Michele while growing up, and led to abundant questions, thoughts, and theories about flora and fauna. Spending her summers in Battle Creek Michigan with a gardening and fishing grandmother, taking Sunday family drives across the border to Windsor, Canada to adventure in the outdoors, endless hours captivated by the Diego Rivera series of frescoes at the Detroit Institute of Arts, and camping trips just below the Upper Peninsula all led to Michele’s passion in scientific discovery and public health advocacy. From Detroit to Ann Arbor to Honolulu to Salt Lake City to the ultimate journey to Moab, Michele has experienced a diverse landscape of people, flora, fauna, and Joy. Prior to settling here in Moab, she was Director and Biosafety Specialist at the University of Utah in occupational and environmental health and safety as well as emergency management. Her professional career began as a specialist at the University of Hawaii in laboratory and agricultural health and safety. Michele received her BS in Botany from the University of Michigan and Masters in Public Health from the University of Hawaii. Always an advocate for making a difference in the lives of our planet’s youth, she has followed the philosophy of “Each one Reach one” and spent many years mentoring the young people in her life.

Program Managers

Brandi Atene

Ya'at'eeh! I grew up in Navajo Mountain, Utah. I am Navajo of the Bitterwater clan born for Towering House clan. Herding sheep on the weekends and during break from school. The landscape in Navajo Mountain paved the way for my love for the outdoors; rock climbing, sleeping outside with cousins, hiking down to Lake Powell to cool off and try and catch some fish. All this without “proper” gear, just the clothes we wore and a water bottle with crackers.

I attended High School in Tuba City, AZ and college at Kansas State University in Manhattan, Kansas. I majored in Architecture, Planning and Design. I played basketball at both schools. A walk on at University. I also ran Cross Country in High School. I coach basketball at the Jr High and High School level. I also donate my time as an official at local youth basketball tournaments.

Aside from my athletic abilities, I love the outdoors. Hiking, camping, fishing, and also being on the river.

I grew up around all kinds of animals. Cats, dogs, chickens, sheep, horse, and cows. Grandparents kept me involved with the livestock. Started with Redwood Llamas in Spring of 2018 for a weeklong hike with Canyonlands Field Institute for their annual Rainbow Bridge Trek. Something about being cut off (electronically), from the rest of this modern world is soothing. Hearing the sounds of nature; animals, wind, casual chats with friends and family. My son always tells me, “Just us, outside, having fun, is the way it should be”, I agree.

Brett Wylder

Growing up in Northwest Arkansas, Brett spent most of their free time outdoors. Encouraged by their parents, Brett started early with climbing and camping which eventually led to paddling. Brett has also worked professionally in Wildland Fire and Wilderness Search and Rescue.  Before coming to CFI Brett founded and directed an outdoor education program at a chartered high school in Arkansas and led upwards of 15 wilderness canoe trips. Brett holds a Bachelors in Media Communications and an Associates in Outdoor Recreation and Leadership as well as certifications in Wilderness Therapy. As a lover of all things public lands, Brett could talk your ear off about conservation, stewardship, ethics, and public land legislation. Outside of work you might run into Brett climbing, fly fishing, gravel biking or trail running with their partner and two dogs.
