Our Origin

Why We Started

"Every patient deserves access to specialized wound care — without the cost and complexity of a hospital setting."

Hill Country Wound Care & Hyperbarics was built on a straightforward observation: too many patients with complex, non-healing wounds were being forced into expensive hospital-based programs — or going untreated altogether.

We set out to change that. By building a physician-led, outpatient specialty practice, we created a setting where patients receive the same advanced wound care therapies available in major hospital systems — at a fraction of the cost, closer to home, and with far more personal attention.

From day one, our model has been built around collaboration. We don't replace your primary care physician or specialist — we partner with them. Every treatment plan is coordinated with your total care team, ensuring continuity, transparency, and the best possible outcomes.

Cost-Efficient Specialized Care

Advanced wound therapies in an outpatient setting — the same clinical quality as hospital programs, without the hospital price tag.

No Hospital Admission Required

Patients receive cutting-edge treatments including hyperbaric oxygen therapy and cellular biologics as outpatients, preserving their independence.

Collaborative by Design

We work directly alongside your primary care physician, vascular surgeon, endocrinologist, and other specialists — keeping your whole care team aligned.

Built for the San Antonio Community

Three convenient locations across Greater San Antonio mean that specialized wound care is accessible to patients who need it most, when they need it most.

Community Involvement

Giving Back to San Antonio

Healing doesn't stop at the clinic door. We're proud to support the broader San Antonio community through partnerships that reflect our values.
