Todd grew up in the countryside of south Georgia and first saw and fell in love with the American West during a backpacking trip to Yosemite. Prior to becoming a backpacking guide, Todd was a teacher in NYC and Atlanta. He has been guiding REI’s Grand Canyon north and south rim backpacking trips since 2008. Since then, he has completed nearly 130 backpacking trips into the canyon. Todd loves meeting each unique group and learning about people’s varied backgrounds and experiences while sharing his knowledge and love of the one-and-only Grand Canyon. A highlight of each trip is seeing the smiles on people’s faces when they reach the rim after four physically challenging but exhilarating days exploring one of nature’s greatest wonders.

Marci Lamoreaux

Marci gives credit for her love of the outdoors to her family experiences as a youth, growing up in the beautiful Rocky Mountains of Utah, hiking, exploring and backpacking. She enjoys the adventure of travel and exploring new sights which goes hand in hand with her desire to guide groups into the Grand Canyon year after year. Meeting new people and seeing them experience the incredible sights along the trail for the first time is always rewarding. Marci loves spending time with her family and supporting them in reaching their goals in life. She is an avid trail runner, ultra marathoner and triathlete and makes an effort to fuel herself with homemade foods and likes to try out new recipes on family and friends. Marci is thrilled to be part of the REI team and looks forward to the adventures that lie ahead.

Caitlin Nave

Caitlin is an enthusiastic, passionate Emergency Department Nurse and Nurse Educator who fell in love with the Grand Canyon 7 years ago on an REI trip just like the one you are about to take. Her enthusiasm and passion is just as evident when it comes to nature, the great outdoors and most especially the Grand Canyon. She looks forward to sharing all the fun facts and her love for the canyon with you and guiding you through this incredible place! When not serving her community in Northern Colorado she is practicing yoga, playing with her furchild, Franklin the Corgi, hiking with her husband and just enjoying/exploring the Rocky Mountains of Colorado.



Brian Marsh

Brian grew up at the foothills of Shenandoah National Park in Virginia and found his love of the outdoors at an early age.  Through cycling he discovered the Colorado Rockies and quickly made the transition to calling Carbondale, Colorado home.  His passion for the outdoors has brought him to become a guide in the Aspen area, focussing on activities such as hiking, rock and ice climbing, mountain biking, and ski mountaineering.  When he’s not guiding, Brian is the head bike mechanic at a local cycling shop in Basalt, Colorado. In his free time he tries to spend as much time as possible rock climbing, exploring new areas on foot, bike, or skis, and loves sharing these adventures with others.



Dave Spies

David Spies first laid eyes on the Grand Canyon in 2005. While floating through the great abyss on a raft he fell deeply in love with the canyon. The connection was so strong that he promptly drove home to New Hampshire, sold everything he owned, quit his career, and moved to Flagstaff. That began a continuing obsession with the canyon. He has been guiding at the Grand Canyon since 2006 and spends free time exploring off trail summits and side canyons throughout the canyon's beautiful backcountry. When not in the canyon David is usually rock climbing or mountain biking throughout the Colorado Plateau region. Sharing knowledge about the canyon and instilling outdoor stewardship in others is a life passion. Beware, exploring the Grand Canyon can become an unhealthy addiction. You have been warned!



Caitlin Jaramillo

Caitlin Jaramillo is an outdoor enthusiast who spends most of her time on top of the tall mountains or in the deep canyons of the West. Growing up on the southern California coast, she had little exposure the the prominent peaks of the intermountain west or the expansive desert of the southwest. It wasn’t until she moved to Flagstaff, AZ for her undergraduate program that she really found a connection with outdoor spaces. Caitlin quickly found every way to get outside whether that be backpacking, white water rafting, rock climbing, or snowboarding. Caitlin is a lover, supporter and steward of the places she spends time in and is passionate about sharing those places with others. While she’s not backpacking, you can find Caitlin running the rivers of the southwest as a river guide. She is excited to share her love and enthusiasm for the Grand Canyon with you!
