About Us

JAMES (JIM) SHEFFIELD, CHT

Program Director

Since 2003 until its recent closing, Jim Sheffield, had been the Clinic Director of the Nix Health Wound Care & Hyperbaric Medicine facility. “We were terribly sad to see the Nix close. It holds so much history and we have so many memories of the patients we met there and were able to help heal. We have treated a huge variety of conditions, including chronic wounds that would have resulted in amputation without treatment. We are excited to invite our patients to our new clinic, Optimal Healing Wound Care & Hyperbarics, at our beautiful, state of the art facility, conveniently located in the San Antonio medical center. We look forward to seeing our patients – old and new – and continuing our mission of helping people heal.”

In addition to working as Program Director,Jim Sheffield and the Sheffield family are founders of International ATMO which, for over 40 years, has been the premier provider of hyperbaric medicine management, consulting and education worldwide.
