A few words from our CEO. 

As the President of CLT, I attempt to pass on the expertise that I have accumulated over thirty years of teaching, both in Korea and overseas.

 

Although over the last twenty years, I have specialized in personal Korean language classes, I have covered a wide variety of subjects in the classroom, on radio and in educational programming.

 

I ensure all CLT instructors are trained to teach essential Korean in the most efficient way to meet the growing needs of the foreigner workforce in Korea.

 

Personally I have experienced the difficulties of living abroad, which is why we place such emphasis on practical real life language and culture training.

 

CLT provides a personalized curriculum to all our students, tailored to fit the unique needs and study goals of the each learner.

 

We aim to make your transition seamless and help you not only achieve your goals, but make wonderful memories in the process.

WHAT PEOPLE SAY

DAVID MELINE, VP/CFO GM

I have been taking language lessons for 12 years consecutively, on 3 continents, and I can say that Diane ranks with the best of the teachers that I have worked with…

GERRY HAYCOCK, PRESIDENT GMAC CAPITAL

My Korean teacher, Diane Eunju Hong, is the best, not just in terms of her exemplary language skills but her cultural insights, knowledge and training all add to a 1st class educational experience…

ART MOMBOURQETTE​​, EXECUTIVE EDS KOREA

A very important aspect has been the flexibility that Diane has in working around my busy schedule…

Ms. Hong accommodated my requests with great enthusiasm, providing me with an experience I won't forget. 

BRIAN LANGLEY, SENATOR OF MAINE

HARRY RUDOLPH, EXECUTIVE

ANNA BAUMAN, SPOUSE OFGM DAEWOO EMPLOYEE

Korean lessons by Ms. Hong were always effective and efficient. She carefully plans the classes to meet the level of every individual student.

HARRY RUDOLPH, EXECUTIVE

VP, KOREA DELPHI

With Diane's support, I was recently able to receive my Certificate of Test Proficiency in Korean, Level 1 and Level 2. 

My journey with CLT ,studying Korean started  when we moved to Seoul in 2019.

 

Soon I realized ,not even a coffee I can order if I don't speak korean .

 

Slowly with no pressure my brilliant and  patient teacher Mrs Sun Mi introduced me the hangul  how to read , write ,pronounce. 

 I started feeling  more comfortable using my  language skills after practicing , pronouncing many many times . I remember my teacher always enlightened me to feel confident and try to speak .

 

With assurance I would recommend CLT language tutorials to anyone whose interested to learn. 

 

Thank you for my teacher Mrs Sun Mi I felt more accepted and I could understand about Korean geography and culture but most inportant people.

I have had the chance to spend three weeks in Summer this year 2022 in Seoul, learning Korean.

I was extremely lucky to find Diane and I contracted her services for an intensive Korean language training.

 

Now with the perspective of more than two months already elapsed, I can only thank her and acknowledge how successful and well organized this was.

 

As a matter of fact, she and the members of her team have gone above and beyond simply "teaching". 

 

She helped with my learning Korean during the three weeks I was there, also providing to me a well-planned assistance for all the necessities -both, prior and during my voyage and stay in Seoul-.

I want to highlight that the teachers assigned to me have proved to be excellent, and at the same time extremely diligent in all their actions.

 

Same comment applies to the staff members and the facilities where the courses were held.

To sum up, if anybody is looking for a teacher and an all around good person to help while in Korea, I can say without any doubt that Diane is the person to contact.
Diane is it!
