What Our Learners Say

My children took intensive lessons for a short period of time in preparation for moving overseas. James has worked with us to achieve our goals and has put in more effort than I would have thought possible at any other English language school.

Kirara (Student's parent)

I am a working adult. I started taking private lessons before starting my new job because I needed English at my new company. The teacher is really attentive to my needs, choosing materials and class topics based on the skills and topics.

Kentaro (Adult student)

The classes are small, so the teachers understand the children's personalities and tailor the lessons to their level, so I feel comfortable attending
