I grew up in the mountains of Colorado bearing an active lifestyle and participating in a wide variety of outdoor ventures and team sports; specializing in basketball and volleyball and soccer. I played Division 1 volleyball my freshman year at the University of California, Santa Barbara, and finished school at Colorado State University. I found CrossFit in 2010 as a new refreshing outlet to my regular training routine and was immediately hooked. For me, it was a new challenge that was effective, stimulating, and just plain fun. Throughout my life, I have valued fitness from not only a performance perspective, but for the purpose of well-being, longevity, injury prevention, and overall health. 


At the time I was only a sophomore in college with an “undeclared” degree, but after finding CrossFit, my passion for health and fitness surfaced and I instantaneously declared and earned a Bachelor of Science degree from Colorado State University in Health and Exercise Science. I earned my first CrossFit Level 1 certification spring of 2011 and immediately began coaching and immersing myself in the world of health and fitness. I then moved to Jackson, Wyoming to complete an internship at Mountain Athlete under Rob Shaul where I met my boyfriend and co-owner of Targhee Athletics Joshua Rempel. Shortly after completing my internship, I had the opportunity to become the head coach and programmer for CrossFit Jackson Hole. In 2013 Joshua Rempel and I decided to share our passion with Teton Valley, Idaho and opened Targhee Athletics in October of 2013. 

When not in the gym you will find me dirt biking.

My passion for health and fitness continues to grow. Witnessing the continuous changes Targhee Athletics can produce in people’s health, well-being, confidence, and overall fitness, I am exceedingly excited to share it with Teton Valley.

I have been involved in sports and outdoor pursuits all my life. I was introduced to the idea of high-intensity gym training from an Outside magazine article covering Gym Jones in Salt Lake City, Utah.  At the end of the article, there was a list of similar gyms throughout the U.S., and Mountain Athlete in Jackson Hole, Wyoming was one.  In 2009, I contacted Rob Shual, and halfway through my first session, realized how unfit I truly was. I trained at Mountain Athlete up until the beginning of 2012, when I made the shift to train sport-specifically for CrossFit. You can become good at CrossFit in a few months, but it takes years of dedication to become great.  Through my journey of self-improvement, I have gained an amazing amount of knowledge from the athletes and coaches that I have had the privilege to meet, learn from, and train with.  For my own personal goals, performance is the driving factor.  But I am very passionate about helping those who want to improve their life-long fitness.

As a child growing up in Rochester, New York, Char O’Brien spent her weekends and summers in the nearby Adirondack Mountains. She has always found the outdoors to be relaxing and re-energizing.  In her youth, she played competitive soccer and found a true love for the team environment.  Moving to Teton Valley in 1996, she discovered mountain biking, hiking and skiing on a whole new level; it has become an essential part of her everyday life. 

Char and her husband, Steve, and their children Tanner and Izzy, find themselves busy with their sports, work and leisure time. They can often be found outside or in the woods camping, and bike riding and exploring the trails together.   

Over the past 20 years Char was a Love and Logic instructor, taught children with disabilities and assisted people of all ages. She finds the gym a grounding place of relief, joy and fun. 


In an effort to help others live a healthy life, Char calls upon her extensive experiences at other gyms. 

“It is a privilege to be a coach at Targhee Athletics.  Josh and Dayne are both amazing and have their hearts invested in their business. With a true love for athletics and the people of our community, they make Targhee Athletics an amazing place to work -  and workout.”
