About Us

Built by Rescuers. Powered by Purpose.

Saint George Hyperbarics was founded by three friends who share a deep commitment to helping people heal.

After flying countless rescue missions together, they saw firsthand how powerful the right intervention can be at the right time.

That experience led them to one conclusion: People in Southern Utah deserve access to the same high-quality, medically supervised healing technologies used in elite recovery centers around the world.

High Standards, Close to Home

At Saint George Hyperbarics, we believe that effective healing happens when advanced medical care meets personal attention.

We use only medical-grade, steel hyperbaric chambers, made in the U.S. and cleared by the FDA, capable of operating up to 3.0 ATA. Our safety protocols, treatment plans, and patient experience reflect our shared background in emergency response: measured, precise, and always prepared.

This isn’t just wellness—it’s real medicine, carefully delivered.
