I am actor Lee Seung Keun, a graduate of the Department of Theater at Seoul Institute of the Arts who completed a master’s degree at Dongguk University Graduate School and coursework toward a doctorate at Dongguk University’s General Graduate School. I have portrayed a wide range of realistic professional characters—including military officers, prosecutors’ office staff, examiners, and team leaders—in productions across platforms such as KBS2, SBS, ENA, tvN, Disney+, and Netflix. With strong action and on-set response skills based on Haedong Kumdo and horseback riding, I have recently also appeared in corporate advertisements for companies including LG U+ and KB Kookmin Bank, bringing a trustworthy image.
