I've really improved my English level thanks to his good tecnique and pedagogy. His lessons are always challenging, variegate and fun. He can really boost your English, I reccomend him ;)

Hein is a great teacher, because he can explain English Grammar much better than the teachers in the middle school. My 11 years old son takes English lessons with Hein and he is getting better in English every day! And my son finaly enjoys English! Thank you!

Buen profesor, siempre te mantiene enganchado en el aprendizaje.

Thanks to him I have just passed my IELTS exam in the UK on Friday. I started from about level A1 and I have progressed up to B1 (score of 4.5). I highly recommend him. He had supported me during whole preparation for the exam. I will continue to study with him to improve my English!

I highly recommend Hein as an English teacher! He prepares each class around your interests and makes every lesson interesting and enjoyable. He is easy to talk to, and the hour goes by so quickly. You learn a lot while having fun!

Hein prepares your classes depending on your interests. They’re always lots of fun and very interesting, and the hour goes by really quickly
