Our Mission

In our welcoming environment, students can feel safe practicing English speaking and listening comprehension, as well as reading and writing. We create authentic and immersive environments where students use English to complete missions. While we do prepare students for exams like the TOEFL and IELTS, our main focus is on developing a well-rounded English proficiency. We firmly believe that with the right support, all our learners can achieve fluency in English to a point where they can use it in their daily lives.

The Problem

Many students struggle with speaking English because it is usually taught without real-life context. Large class sizes leave students little time to practice their skills, while small class sizes often obsess over memorization and question completion. Students at all levels are not practicing English in the way it was meant to be learned – through real-life application with purpose.
