Years Experience
The Founder
Amanda Barnett
Movement has always brought me joy. Even as a kid, I loved testing my limits and feeling what my body could do. That joy is what pulled me into the fitness world more than 25 years ago, and it's what still drives me today.
Fifteen years into owning Lacon Fitness and Tan, I realized something powerful: people don't just need a place to workout. They needed support, accountability, structure, and a community that believed in them. That realization is what sparked Thrive Fitness.
As a wife and mom of three, I know that staying healthy gives me more opportunities to have experiences with my friends and family. My mission is simple: create a place where everyone feels accepted, encouraged, and proud of their progress.
