Natalie Brechtel

Assistant Guide

Natalie has been an outdoor professional for over 15 years, and has climbed and explored on all seven continents. Originally a San Diego native, she spent her youth camping and backpacking in the southwest. She currently travels all over the US to guide mountaineer trips, or to teach wilderness medical courses, but calls California home.

Lindsay originally began working in the Sierra in 2006. Now, a decade later, she bases in Bishop near the gorgeous landscape of impeccable granite. When Lindsay isn’t climbing you can catch her playing guitar and singing at local cafes.  Lindsay is an AMGA Certified Rock Guide, AMGA Assistant Alpine Guide, AAIRE Level 2, Certified Wilderness First Responder & a Leave No Trace Trainer.

More About Andrew

Being well-rounded, Andrew also does carpentry work and runs a maple syrup company. He would never tell you himself, but Andrew is a master at everything he does: he climbs as hard as he races down hills on skis, but his humbleness would never reveal it.  Andrew is an AMGA Certified Rock Guide and has a Wilderness First Responder.

Santa Barbara, where she did research and education on health, nutrition and movement.  She is certified as an EMT-B and Wilderness First Responder, and holds certifications from the AMGA, AIARE and is a Leave No Trace Trainer.  Natalie spent 5 years managing UC Santa Barbara’s outdoor program and ropes courses, feeding her passion for outdoor education.  She has worked for that National Park Service as a Park Ranger, and as part of Yosemite Search and Rescue. Chasing adventure, Natalie began an obsession with working and exploring in Antarctica.  At one point she spent over 14 months straight on the frozen continent and experienced winter in the coldest place on earth! She has been a part of the US Antarctic Search and Rescue, and Auxiliary medical team along with her work as mountaineer and in field camps.

In essence, Natalie has worked some of the most wild and remote jobs imaginable in the pursuit of outdoor exploration both for herself and others.   Helping others reach their goals, grow in confidence and develop a love for the outdoor is one of Natalie’s specialties.   It’s also the most rewarding part of her work.

When not teaching or guiding you can find her somewhere high up on a rock or deep in the mountains she loves.


Trevor Anthes

He has a close familiarity that comes from decades of playing, working, and living among these mountains. From alpine rock routes in the Palisades to ice climbs in Tuolumne and Yosemite, you will find him just as comfortable hiking the JMT in summer as doing a tran-sierra on skis.

More About Trevor

Consequently, Trevor is as willing to take a casual ski tour as to engage in a steep descent, or to scramble up an easy ridge as to attempt a technical rock climb, usually with his camera strapped to his chest capturing some future work that you can view at his website.  www.wildincognito.com

The best part of adventuring with Trevor is the constant smile you will see from him.  Whether its rain or snow, hard or tiring, Trevor never ceases to amaze you with a genuine, ear-to-ear smile…taking it all in.

“Trevor Anthes was fantastic, and I could not have asked for a better guide. Of course, it was great to have someone who really knows the route down at the 10 ft scale, as well as at the quarter mile scale.  He also gave me a lot of “room” to walk at my own pace and handle the difficult spots without overdoing the instructions.” Client – Stu Pettygrove
