About Us



    To me, fitness is so much more than just spending time in the gym. It’s about how that time and hard work effects every part of life. It’s about being strong and capable, avoiding injury, and if I’m being honest, staying active as long a possible. There is a reason why the West Slope is the best slope…we have endless access to adventure right in our own back yard! There is nothing better than “working out” without thinking about working out. I believe that one of the most beneficial ways to living a healthy life is finding things that you enjoy, that also happen to be active. Sweating while you have a giant smile on your face…winning! Combine that with muscular and core strengthening, flexibility, balance training, a healthy/happy diet and that seems to do the trick.

     I started my journey in Outdoor Education, and then spent three years as a wildland firefighter, where I really began to realize the benefits of strength and endurance conditioning in accordance with work and play. That led me to pursuing a career in health and fitness. I attended the National Personal Training Institute (Denver), followed by completing my BA in Kinesiology, Fitness and Health Promotion at CMU. Throughout eight years in the field, I have worked in collegiate strength and conditioning, personal training, teaching group fitness classes and have now landed in the dream of being a co-owner in our very gym/studio. Let’s hang out!
