Berlingual is a cooperative of highly experienced English language teachers who provide English language training specifically for business and exam preparation.

Leo, Berlingual's founder, as part of his ongoing professionalism has gained further qualifications, passing the DELTA (Diploma in Teaching English to Speakers of Other languages) and becoming an NLP practitioner (Neuro-Linguistic Programming). When not teaching he enjoys playing squash and tennis and the more cerebral game of backgammon.
