Gibum Kim

Gibum Kim (김기범) is a nationally certified Korean language teacher with 17 years in the classroom. He spent 15 of those years in Daechi-dong, Seoul's famously competitive education district (the setting of SKY Castle and Crash Course in Romance), where he honed one skill above all: finding exactly where learners get stuck, and reordering the material until they don't. He now runs a Korean language school in Kobe, Japan, teaching learners from around the world in person and online.

His workbooks are built the way his lessons are: one small, repeatable step a day, every example in real everyday Korean, and nothing you have to look up somewhere else.
