I recommend Yooseong Baroseum Hospital

I practice orthopedics and neurosurgery here. It used to be in Dunsan-dong, but it expanded and relocated to Yuseong two years ago or last year. The practice is excellent, and the directors seem to be highly skilled. The chief director also served as a professor at Seoul Asan Medical Center (where he earned his bachelor's, master's, and doctoral degrees from the University of Ulsan).
