Todd Kolberg

Owner, ACE L1-L4 Lead Instructor - Los Angeles, ACE L5 Certified Guide, Canyoneering & Rappelling

Growing up in Wisconsin, Todd spent summers camping at his aunt & uncle’s campground, swimming in ponds on the farm, waterskiing in the river, and snowmobiling in winter. After moving to Los Angeles, Todd attempted to overcome his fear of heights by taking accelerated free-fall skydiving training, He soon started looking for something closer to the ground that was more social, more scenic, better exercise, and more enjoyable. He quickly got turned on to canyoneering and has since explored canyons throughout the western states as well as islands in the Caribbean. A certified Wilderness First Responder, Todd is also a full-time lecturer at USC, loves to teach, and is thrilled to share his love of canyoneering with others.

Jason Marvin

L1 Instructor, Canyoneering & Rappelling

I have been an outdoor enthusiast since 2003, mainly revolving around outdoor cross-country travel and exploration. I finally found out about the exciting sport of canyoneering in December of 2013 and began training with Uber Adventures. Focusing on learning the fundamentals and safe practices of canyoneering I quickly realized I had the canyoneering bug. In this sport, the things I find most satisfying are: 1) being able to safely descend deep into these beautiful, rarely seen places, and 2) the camaraderie and teamwork that I have not experienced in any other sport.

Derek Lorentz

ACE L1-L4, Lead Instructor for NV courses

Born in Arizona, I’ve spent most of my life loving the endless recreation the desert southwest has to offer. While you might find me taking my two kids climbing, hiking, mountain biking, or just outside in general, on-rope in a canyon is where we are happiest. The diversity of technical challenges, scenery and companionship in canyoneering has proven to be second to none and can “scratch the itch” and bring people together like no other sport!

After graduating from The University of Michigan I travelled to Scotland and completed a graduate degree in Outdoor Education from the University of Edinburgh: I worked with Indiana University Outdoor Adventures and received my EMT and Wilderness EMT certifications, eventually becoming a Paramedic and Professional Firefighter. Today I run backpacking trips across the US and instruct Wilderness First Aid, Wilderness First Responder and Wilderness EMT courses.

Ben Lewis

Owner, ACE L5 Certified Guide, ACE L1-L4 Lead Instructor - Las Vegas, Canyoneering & Rappelling

Originally from the Midwest, the Great Plains didn’t offer enough vertical excitement for me and I knew I’d eventually leave. That opportunity came with a new job travelling the world with Cirque Du Soleil. I spent my free time of the next decade as an Ecotourist hiking, paddling, and playing in the wilderness. I settled down in Las Vegas in 2014 and Canyoneering quickly became my favorite outdoor activity. When not descending canyons, you’ll most likely find me Ultra running in the desert and mountains.

Cort Wright

L1-L4 Instructor, L5 Certified Guide, Canyoneering

Cort grew up exploring the outdoors in the west with his family.  Hiking, backpacking and rock climbing being some of his favorite hobbies.  It wasn’t until 2009 that he was first introduced to the sport of canyoneering as a guide for an adventure company in Moab, UT.  It was here that Cort’s passion for the sport grew and inspired him to learn as much as he could.  It didn’t take long to realize that canyoneering was a sport of zero margin for error, which led Cort to seek out instruction and guidance from industry experts.  This passion for knowledge and best practices led Cort to Uber Adventures and the ACE Canyoneering courses.  Cort now manages at the same outdoor adventures company taking thousands of people through local canyons, and teaches the Moab courses for Uber Adventures.

Jason Shaffer

ACE L5 Certified Guide, Canyon Guide in Nevada

I have always loved the outdoors.  I was always stomping around the woods as a kid and after joining the USMC I learned land navigation, rapelling techniques, and put more miles on my boots than I could count.  When the opportunity came I moved to Las Vegas and that’s where my love of climbing and canyoneering was realized.  I started rock climbing and canyoning 9 years ago and during that time I received expert education from Uber Adventures from basic rappelling to the ability to guide groups of individuals with or without experience, and am looking forward to guiding locally.

Jeremy Eng

ACE-L1 Instructor, Canyoneering & Rappelling

Jeremy was born in raised in an area foreign to canyoneering, a village in the far-east, Columbia, Maryland.  He started following his love of the outdoors in 2001 and since then has spent most of his free time rock climbing.  At least it was that way until 2003 when Aaron Ralston showed us all the beauty of Utah slot canyons.  Jeremy saw these destinations and quickly sought out the sport of canyoneering.  Since then, with training from the ACA, Uber Adventures, AMGA, LNT, and REI, he continues to explore canyons and climbs throughout the southwest.  Jeremy is always excited to help spread the enjoyment of these addicting sports with others.

Cole Anderson

Owner, ACE L1-L4 Lead Instructor - Arizona, ACE L5 Certified Guide, Canyoneering & Rappelling

I am from Minnesota and grew up running and playing ice hockey. In high school, I got the outdoor bug while canoeing through the BWCAW and miss being able to do that. Backpacking, climbing,  and canyoneering have helped fill that void. I moved to Arizona in August 2014, but it wasn’t until April 2019 that I began technical canyoneering. Shortly after I began, I was able to join a group doing The Subway and have spent most weekends exploring canyons in the southwest since. The beauty of these canyons and the challenges they can  present are a big part of the reason I love this sport. I find it difficult now to leave the rope behind on any trip I take.
