Meet Your Instructor

Hi there, my name is Grant Sundbye, and my job is to help you become the best English communicator possible. 

Over the past four years, I have helped hundreds of Korean professionals exactly like you improve their work performance by becoming better, clearer, more confident English presenters. 

I first worked at FastONE, a 1:1 business English 학원 in 강남, where I was one of the most popular and highest-rated instructors in the entire company.  

Perfect Student Reviews

5.0/5.0 average for five months straight

Top Instructor Awards

Multiple time 'Instructor of the Month' and 'Instructor of the Quarter' winner

Tons of Happy Clients

My schedule was almost always 100% full due to huge demand for my classes

After completing my contract at FastONE, I founded my own online company Grant Sundbye: Business English Coaching. 

Since founding my business, I have:

  • Worked with hundreds of Koreans in all industries & at all English levels
  • Helped Koreans get promoted, move abroad, get better jobs, increase their salaries & more
  • Published a bestselling book with 길벗
  • Built an online following of over 25,000 people
  • Spent thousands of dollars & countless hours learning everything I possibly can about business communication

I was the top instructor at FastONE, but I can say with confidence that I'm a much, much better teacher now than I was then.

Frequently Asked Questions

How Long Do I Get Access to the Course?

It's yours forever :)

What if it takes me longer than 7 days?

That's no problem! I'm sure you have a busy life. You can go at your own pace, the course is yours forever :)

Is My English Good Enough?

If you can understand most of the video and content on this page, your English is good enough to understand this course.

Will I Get To Have Classes With You?

Yes! After you complete the course, you'll get a private coaching session with me to practice one of your full presentations and get all the tips/feedback you need to make an incredible impression in the workplace.

Why Can't I Just Have Classes With you Instead?

Great question.

1. This is the exact same information I would tell you in a live class, only here it's more organized and much, much less expensive.

2. The better you are at something, the more people want to work with you. My business has grown a lot over the past 2 years, and I now have more people wanting to work with me than I have time for. I could solve this by charging incredibly high prices that only a few people could afford, but I would much rather share my knowledge with everyone.
