More Than a Gym-A Community Committed to Lifelong Fitness.

A healthy life is a good life. We provide fun classes for you to be challenged, encouraged and successful. We believe in building relationships, coaching our members and caring for one another.

We’re the coaches at Trailhead CrossFit

The staff and coaches at Trailhead CrossFit’s mission is to educate, motivate, and connect with every member of our community, guiding you toward long-term success. Our passionate coaches are the heart of Trailhead CrossFit—not just as trainers but as people who have walked the same path as you. They started CrossFit to get healthier, lose weight, and build strength, just like many of our members. When they’re not coaching, you’ll find them on the trails, staying active, and leaning on the same community for accountability and support. Each coach brings unique expertise and energy to help you progress, overcome challenges, and reach new heights in your fitness journey. Your success is our success.

Snippet about balance, enjoying the outdoors, family and fullfilled life…

At Trailhead, being a happy person to us means feeling fulfilled in your life and the choices you have made. We focus on the positive and always seek to improve in all aspects of our life. We want the best for ourselves and others.

Remember, lighting someone else’s candle doesn’t put out your fire!

Instead it pushes you to shine even brighter.

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.
