Strive's Foundation

Strive Performance & Mobility was founded with a simple but powerful belief: fitness is for everyone. As a locally owned, family-run gym, we built Strive to be a place where people feel welcomed, supported, and challenged — no matter their starting point. We believe people are capable of doing hard things when they are supported by educated coaching, meaningful community, and purposeful movement.

Our team brings together strength training, group fitness, and physical therapy under one roof to help people move better, feel stronger, and stay active for life.

​​

"Strive is more than a gym to us — it’s a place we built for our family and our community,

and we’re grateful to share it with you."
— Casey & Kirsten Stauffer
