Jonathan K. Bushman, D.O., Vice Chair
Term: June 5, 2026
Jonathan K. Bushman, DO is proud to join the movement of physicians nationwide calling for a shift in primary care delivery. A native northwest Oklahoman, Dr. Bushman returned to the area for Family Medicine residency training through Integris Bass Baptist Health Center after graduating from Oklahoma State University College of Osteopathic Medicine in 2010. Following his last year as chief resident in 2013, he joined Integris Medical Group as an outpatient family medicine physician at Family Care Services of Enid with his friend and mentor, Dr. Dwayne Janzen. Dr. Bushman is gracious toward Integris for the opportunity to serve many patients in the last five years while participating in various leadership roles and training. He has had the opportunity to serve alongside many amazing people that will not soon be forgotten!
As an undergraduate at the University of Central Oklahoma, Dr. Bushman pursued a degree in Political Science with an emphasis in Public Administration while obtaining his pre-medical education as well. He finished his degree with a capstone, 50-page paper entitled "The Rising Costs of Healthcare: Shifting the Responsibility". In that paper, Dr. Bushman elaborated on the numerous third-party interests in medicine that have compiled to create the complex, burdensome healthcare system that we have all come to know. Through medical school, residency training, and beyond, Dr. Bushman has persistently sought to simplify care and direct his efforts more and more toward patients. Upon visiting and observing firsthand how the direct primary care model works, he has embraced the model of care and the players within the national movement. With Direct Primary Care, Dr. Bushman sees an opportunity to be part of a greater mission within the political and business arenas of medicine to achieve meaningful change in the way healthcare is delivered.
Dr. Bushman is blessed to have the support of his beautiful wife Andrea, and he is a proud father of Avery (12) and Aidan (10)! Having called Enid "home" for the past 8 years, Dr. Bushman looks forward to serving the Enid community and surrounding area for many years to come!!
