My Background

Hello, my name is Sunghoon (Sun). I’m a native Korean speaker and a certified Korean language teacher, officially recognized by the National Institute of Korean Language.

I have over 5 years of teaching experience both online and in-person since early 2020. I’ve taught hundreds of students around the world from all walks of life. My students have various reasons to take lessons – studying or working in Korea, taking up a new hobby, re-connecting with their family of Korean heritage and more. They are making progress each week to reach their goals.

Whatever their reason, they’re making steady progress toward their goals — and you can too.

I strive to be a respectful and open-minded individual, and I deeply respect people who challenges themselves to learn. Learners of all ages, nationalities, professions, and genders are welcome.

My Teaching Methods & Style

I believe a good teacher embodies patience, clarity, and presence.

Here is what you can expect from my classes:


Learn at your own pace in a supportive environment:
You’ll be encouraged to make mistakes, speak with ease, and build confidence through trial and error.


Structured learning using a variety of teaching materials, including textbooks from Korea’s top language schools and trusted online resources like Talk To Me In Korean.


• Clear explanations of grammar and vocabulary: You’ll be able to understand the usage and the subtle nuances.


Practical and interactive lessons featuring role-plays, natural conversations, and cultural exchanges to keep learning engaging and fun.


Tailored lesson plans designed to match your level, specific interests and goals.
