Richard Kim

CEO and President,
Board Certified Radiologist

Dr. Kim’s family immigrated to Chicago from South Korea in 1977 when he was 11. His parents made a living running a diner on Roosevelt Road in Chicago. He helped his parents every weekend and summer. After he graduated from the University of Chicago, he took over the business to support the family while he worked through his next steps. The very demanding diner business made it a rather easy choice to seek a career in medicine – something both of his parents dreamt for themselves a generation before. The intensity of the diner business gave him an unrelenting work ethic and a belief in providing exceptional customer service. After five years, he matriculated at Rush Medical College, moved on to become a radiology resident and subsequently an interventional radiology fellow at The University of Chicago Hospitals. He founded GK Medical Management in 2005 and has been CEO since that time. In 2002 he joined Sinai Health Systems to serve as the Chairman of Radiology for five years.
