our story

BUILT HERE. BUILT FOR YOU.

ONYX Fitness Club is a locally owned fitness and wellness club founded by brother-and-sister team Ghaith Kurdi and Adelita Cheadle with a simple vision: to create the kind of gym our community deserves.

Our goal is to create a space where people come to work.

A place for serious training without the ego. A place where beginners can walk through the same doors as experienced athletes and feel like they belong. A place where quality equipment, personal training, thoughtful design, wellness, recovery, and a strong community all exist under one roof.

As a locally owned family business, we’re personally invested in what happens inside these walls. Every improvement, every piece of equipment, every coach we bring on, and every detail of the ONYX experience is considered with our members in mind.

We’re building ONYX around what we believe modern fitness should be: 24/7 access, premium training, experienced coaching, wellness, recovery, and a community of people committed to becoming stronger versions of themselves.

ONYX is still evolving—and that’s intentional. We’re constantly listening, improving, and investing back into the club to create something Santa Maria and the Central Coast can be proud to call their own.

This isn’t a corporate gym.

It’s personal.

It’s local.

And we’re just getting started.
