OU Health physicians earned more than 150 recognitions on 405 Magazine's annual Top Doctors list, including honors in prestigious categories such as Rising Stars and Legacy. Selected through an online peer nomination process, the recognition reflects the respect OU Health physicians have earned across the medical community.

This year’s Rising Star honorees from OU Health are John Burke, M.D.; Christopher Graffeo, M.D.; Thai Do, M.D.; Syed Muhammad Shakaib Quadri M.D., MS, and Scott A. Vadala, M.D. Legacy honorees are Jill S. Warren, M.D., and Mary Zoe Baker, M.D.

As the University of Oklahoma’s academic health system, OU Health trains the doctors of tomorrow and is uniquely positioned to serve all of Oklahoma. OU Health cares for the sickest patients as a top tier academic referral center and provides research driven, multidisciplinary care and unique, life altering services through destination programs with robust research to help patients achieve the best outcomes.

“Peer recognition matters because it reflects excellence at the bedside and in the lab and classroom,” said Ian F. Dunn, M.D., FACS, FAANS, chief physician executive for OU Health and executive dean of the University of Oklahoma College of Medicine. “As Oklahoma’s flagship academic health system, our physicians care for the most complex patients, advance discovery that changes practice, and train the next generation of clinicians and scientists for our state and region. This acknowledgment from colleagues underscores the impact of academic medicine on outcomes for Oklahomans.”

OU Health brings together more than 1,000 physicians representing virtually every medical specialty. The academic health system integrates advanced subspecialty training with specialized care, providing Oklahomans access to treatments and expertise found at the nation’s leading health systems. As the state’s only academic health system, OU Health ensures Oklahomans don’t have to leave the state to receive top-tier care.

The Top Doctors recognition spans 47 specialties, from primary care to highly specialized fields including cardiothoracic surgery, neurological surgery, and pediatric subspecialties. OU Health Stephenson Cancer Center, Oklahoma Children's OU Health, OU Health Harold Hamm Diabetes Center, OU Health University of Oklahoma Medical Center, OU Health Dean McGee Eye Institute and OU Health clinics across the state are among the facilities where these honored physicians practice.

“Academic medicine offers patients something unique — physicians who are not only expert clinicians but also researchers and educators pushing the boundaries of what's possible in healthcare,” said Dunn. “One of the most distinctive aspects of the University of Oklahoma academic health system is that all physicians caring for patients at OU Health are faculty members at the University of Oklahoma College of Medicine. This means patients receive evidence‑based care informed by research and delivered by collaborative teams focused on improving outcomes."
