We’re proud of our health system, and we strive to improve every day. Some of our successes include having Oklahoma’s only ACS Level II trauma center and northeastern Oklahoma’s only Joint Commission-accredited stroke center. We have one of Oklahoma’s only accredited women’s diagnostic imaging centers of excellence. St. John brought many advanced technologies to Tulsa, including the first endovascular operating suite, all-digital diagnostic radiology, the da Vinci surgical robot and the CyberKnife non-invasive radiation system.

St. John Medical Center is Tulsa’s first Magnet-recognized hospital for excellence in nursing, and it was recently ranked the #1 Oklahoma hospital in U.S. News & World Report’s 2017-2018 Best Hospitals rankings. 

These achievements reflect what is in the hearts of our experienced staff of doctors, nurses and team members: a commitment to serving northeastern Oklahoma through every challenge and triumph.
