It was around 2003 when Dr. Cho came back from New York and opened a psychological clinic in Seoul.
A headmaster at an English-speaking international school contacted Dr. Cho
by phone and explained his troubling situation in detail.
“Dr. Cho, we have a student who has been attending our school for a long time, but he has difficulty learning the English language and there is no academic progress. Thus far, we have helped this student in every way we could,.....I know that his parents have tried to help him from private tutoring to Hagwons (private academic institutions).
Do you have any other way to help this student?"
Dr. Cho did not turn away from the children who lost all their hopes because they could not acquire the English language at their English-speaking schools. Instead, Dr. Cho started providing bilingual comprehensive psycho-educational assessments and treatments.
