Before that she worked in Agape Language Institute 2007-2009 as a Jolly Phonics teacher. She has Association Montessori International (AMI) Certification for 3-5 years old children and a bachelor degree in Kyungbuk National University, where she did a double major in psychology and child-family studies, with a minor in English. She loves Jolly Phonics so much because it gives confidence to everyone – not just children, but adults too! She wants to help many people, especially children and teachers, to have confidence in English. She is eager to train more teachers because she believes that Jolly Phonics is the best way to achieve that; during her teaching experiences she has seen children and teachers who gained confidence in reading English words through Jolly Phonics.
