Dr. Jaewon Ryu
President and CEO, Geisinger
In the top position at Geisinger since 2018, Ryu is slated to become CEO of Risant Health, a nonprofit created with Kaiser Foundation Hospitals that aims to acquire Geisinger in 2024. Plans call for Risant to acquire five or six other health systems over the next five years to build a national network for value-based care. At Geisinger, Ryu has championed the use of digital tools, including an artificial intelligence algorithm targeting high-risk patients for health screenings. The organization under his leadership has also improved operational efficiency and boosted primary care for seniors, sharply reducing inpatient admissions and emergency department visits. Ryu serves on the Medicare Payment Advisory Commission. He previously was president of integrated care delivery at Humana; a corporate healthcare attorney at McDermott, Will & Emery; a White House Fellow at the Department of Veterans Affairs; and an emergency medicine physician at Kaiser Permanente.
