Our Board places a strong focus on developing talent throughout all levels of our organization, with the goal of fostering leaders who embody our core mission that has guided Geisinger for more than 100 years. Dr. Ryu is a great example of this, and I and the other members of our Board look forward to working with him and the entire leadership team as Geisinger continues to deliver exceptional care to our patients, our members and our communities.”

Dr. Ryu commented, “When I joined Geisinger more than two years ago, I knew I was joining an organization with a longstanding national reputation for advancing medicine through innovation. What I quickly discovered after I began working here, is that the strength of Geisinger stems from our great people and communities. As a practicing emergency medicine physician, I have the privilege of working alongside many of our outstanding caregivers. That firsthand view of their expertise and unwavering dedication inspires me every day to keep my focus on our purpose of caring for our patients, members, employees, physicians, students and the communities we serve. I am honored to take on the role of interim CEO at this important time for Geisinger and the healthcare industry. Together with our outstanding leadership team and the commitment of our 32,000 employees, we’ll build on our legacy of putting patients at the center of all that we do and maintain our commitment to research, education and innovation.”

Dr. Feinberg has led Geisinger through a significant period of transformation focusing on developing innovative programs and models to further our mission of value- and community-based care that ensures we are positioned to serve our communities well into the future. We are deeply appreciative of his service to Geisinger, and we wish him only the best.”

Dr. Feinberg said, “It has been a great privilege to lead Geisinger during the past nearly four years. Together, we have improved patient and member experience, along with our quality of care, employee engagement and physician and nurse recruitment, and our legacy of innovation has blossomed. I know that I am leaving Geisinger in capable hands as the leadership team continues to advance Geisinger’s important mission of taking care of the people we serve. I look forward to following Geisinger’s achievements in the years to come and will remain forever grateful to have had this tremendous opportunity.”
