I’ve taken his Callan lessons several times.
I think he is good at teaching English.
When I ask a question , he uses sample words to explain. So I can understand what he says.
He is gentle and calm enough for me to relax.
I don't feel nervous because he is always smiling during the lesson.
And we talk about various things (Japanese foods ,cultures, our favorite things etc ) .
I enjoy his lesson every time.
