The Team

Our teachers not only speak English – they live it.


The heart of our school is the team. What connects all our teachers is their native language of English and at least one recognised credential for English teaching such as the CELTA or TESL certificates.

Team Wängi

Wängi is our second location, which emerged from the Speak English language school. I wonder who works here? See below!
