The United States is home to one of the largest populations of people of Korean descent. On the occasion of Korean American Day 2025, we talk with Julia Sim – a decades-long St. Louisan and president of the Korea Academy of St. Louis – about how she’s approached Korean language and culture education, for children and adults. Hyung Kyu Choi, current KASL teacher and parent, also shares personal reflections about language’s place in the experience of diaspora Koreans like himself, and in raising his young Korean American children in St. Louis.
