Our Story.
Your Gym.

St. John Fitness was built from the ground up by us, a husband-and-wife team with a shared belief that everyone deserves access to a great place to work out.

As a military veteran and a self-made entrepreneur, we, Thomas Kelly and Sybille Sorrentino, set out to create a fitness center that serves both the people who call St. John home and the visitors who want to stay active while enjoying everything the island has to offer.

What started as an idea grew into a locally owned gym built with our community in mind. We live here, work here, and care deeply about the island and the people who make it such a special place.

Whether you're maintaining your routine while on vacation, training for a specific goal, building strength, or simply looking for a place to move and feel your best, we're here to support you. Our goal is to provide the equipment, space, and welcoming atmosphere you need to make every workout count.

We're grateful for every member and guest who walks through our doors. Thank you for being part of our journey. We look forward to being part of yours.
