Diagonal English arose  with the idea of improving our approach to teaching English while embracing new technologies.

Over the years, we’ve been able to witness the advantages of a methodology that is based on using the language in the classroom, not only seeing the language as a set of grammar rules to study.

Our years of experience has allowed us to analyse our approach and in turn develop a system of learning English that is natural, fast, fun and effective .

Diagonal English is the new and most advanced approach to learning English

Classes at Diagonal English adapt to the needs of the student, both in one to one classes as well as in small groups. Groups consist of learners with similar objectives and profiles as we believe small, carefully formed groups are the foundations on which to build an effective course.

In class, we provide opportunities for authentic, engaging, and enjoyable speaking practice across a range of topics relevant to our learners. Whether it be for work, studies, travelling or everyday situations, we offer opportunities for varied and stimulating practice with a view to building fluency.

Where knowledge is lacking, we provide concise, targeted input with emphasis always placed upon our ultimate goal; clear and effective communication.

Grammar rules can be helpful, however If our ultimate goal is to be able to communicate in English then only through the practice of the language with guided input from experts can we improve our communication skills – and this is where Diagonal English can help you.
