TULSA/OKLAHOMA CITY, OK (Dec. 4, 2025) – EMSA, Oklahoma’s largest provider of pre-hospital emergency medical care, has once again earned national accreditation from the Commission on Accreditation of Ambulance Services (CAAS), a distinction only 1% of all EMS agencies nationwide achieve. EMSA received a perfect score, placing it among the nation’s most elite emergency medical service providers.

CAAS accreditation represents the gold standard in the ambulance industry. The process includes a detailed self-assessment and an independent, external review of all areas of an organization’s operations, including administration, safety, dispatch, clinical protocols, and continuing education, and concludes in a comprehensive on-site evaluation of more than 300 standards.
“Earning CAAS accreditation is an incredible achievement, reflecting the skill, professionalism and dedication of our entire organization,” said Johna Easley, EMSA President and CEO. “A perfect score demonstrates our unwavering commitment to setting the highest standards in patient care, quality, and continuous improvement across every aspect of our service.”
Only two ambulance services in Oklahoma currently hold CAAS accreditation, and only 215 nationwide meet the commission’s comprehensive standards. Achieving a perfect score through this process places EMSA among an even more exclusive group of emergency medical service providers.
“CAAS accreditation is the most respected benchmark in the EMS industry,” said Tammy Powell, Chairperson of the EMSA Board of Trustees and President of St. Anthony Hospital in Oklahoma City. “Earning a top score in such a rigorous independent evaluation of all areas of EMSA’s operation reinforces that our communities can trust they are receiving excellent EMS care every time EMSA responds.”
EMSA has held CAAS Accreditation since 2010 and goes through the reaccreditation process every three years.
