The CFSTC Story:

In 2016, Jason was at a crossroads. As an IT business owner, his long hours and sedentary lifestyle had taken a toll on his health. Fitness had always been a struggle—his routines were inconsistent, and results never lasted. When he signed up for a Tough Mudder race that year, he hoped it would be a turning point. Instead, it became a wake-up call. A foot injury during the event led to an urgent care visit, where doctors revealed two hard truths: he was pre-diabetic and more than 40 pounds overweight.

Determined to take control of his health, Jason searched for a sustainable fitness solution. His wife suggested CrossFit, and he reached out to CFSTC. Within minutes, he received a response from Kim Wilkes, the owner, welcoming him to the gym. From his very first class, Jason was hooked. The intensity of the workouts, the camaraderie among members, and the unwavering support of the coaches made an immediate impact. CrossFit wasn’t just exercise—it was a lifestyle, one that challenged him physically and mentally in ways he had never experienced.

Over time, Jason’s dedication to the sport transformed not only his body but also his mindset. He lost weight, gained strength, and rebuilt his confidence. But beyond his personal progress, he discovered something even more rewarding: a deep passion for helping others experience the same transformation.

By 2020, that passion led him to earn his Level 1 CrossFit Trainer certification. Coaching became more than just a role—it was a source of joy and fulfillment. Jason thrived on seeing others achieve milestones they once thought impossible, and he dedicated himself to becoming a better mentor. He pursued additional certifications, including his Level 2 CrossFit Trainer and HSN Nutrition credentials, ensuring he could guide members not just in workouts but in overall health and wellness.

When the opportunity arose to purchase CFSTC and carry Kim’s mission forward, Jason didn’t hesitate. For him, this wasn’t just a business venture; it was a chance to give back to the community that had changed his life. He knew firsthand what it felt like to walk through CFSTC’s doors searching for a fresh start, and he was committed to making sure others found the same support, encouragement, and transformation.

CFSTC Today: A Vision Fueled by Experience

Under Jason’s leadership, CFSTC continues to thrive as a space where fitness meets community. His journey from an out-of-shape newcomer to a passionate coach and owner serves as an inspiration to every member who walks through the doors. He understands the struggles, the setbacks, and the victories because he has lived them.

At CFSTC, the mission remains the same: to create an inclusive, supportive environment where people of all backgrounds and fitness levels can push their limits, build confidence, and change their lives. Jason’s story is a testament to the power of perseverance, the impact of a strong community, and the belief that fitness isn’t just about working out—it’s about transformation, inside and out.
