Your Progress Stokes our fire
Seeing our members crush their goals fires us up! That’s why we never stop learning, listening to your feedback, and adding new classes—so you always get the most fun, effective, and inspiring fitness experience possible.
Why we do what we do
The core of what we do is so that our community can live a more adventurous life. Which for Trailhead is defined as shared experiences with loved ones. And although everyone’s adventure is different, from endurance races to being able to play with grandkids, the beauty is that consistency in the gym leads to a flourishing life outside of the gym.
Our Mission
At Trailhead CrossFit, our goal is to build a family of healthy, happy people who kick ass well into their 90s. We believe fitness is more than just exercise—it’s a path to a longer, more adventurous life. Rooted in fun and connection, we know that shared experiences with those around us fuel our greatest growth. Our purpose is to awaken a lifelong love for fitness by fostering a community that keeps that fire burning, helping every member thrive for a lifetime.
