Castle's English Institute consists of four branches based in central Switzerland. The main office in Zug was founded in 1979, followed by Lucerne in 1983. There are two other offices in Thalwil and Basel. As well as being a language school we also act as an agent advising students and professionals who wish to study a language abroad. Our main areas of business are general and business English courses, exam preparation courses, summer programmes for young learners, English for specific purposes and 1:1 courses. High school years and work/study programmes are also gaining in popularity. Organising groups to go to schools abroad is a specialist area in which we have lots of know-how. Being experienced, qualified teachers of English ourselves, we are in a position to evaluate our clients' level of English accurately and advise them accordingly.
