English courses

I teach in-house courses on all levels in technical English on the customers’ premises. My courses are planned and taught according to the customers’ specific needs. The employees don’t need to leave their working place, but can attend a course any time during their working hours. I also teach courses in everyday English.

During my studies in the late 1970’s and early 1980’s I taught courses in technical English and everyday Spanish at several companies in Turku, Finland.

When I moved to Switzerland in 1983 I continued teaching English first at the Migros Schule and then at Styner & Bienz in Niederwangen and later at BLS AG Bern, where I am teaching presently.

I have also taught courses in technical English at the Volkshochschule in Bern.


"Ms Naef is a competent teacher committed to her work. She plans and prepares her courses very seriously. But she is flexible and always ready to modify the day’s program according to her students’ wishes. I appreciate Ms Naef’s ability to create a motivating and relaxed ambience in the classroom that is very important for the learning process."

German courses

I offer courses in everyday German especially to Chinese speaking customers. My own basic knowledge of the mandarin Chinese language and the Chinese culture as well as my experiences in teaching English and German courses in China and in Switzerland are of big advantage in this work.


“Ms Naef taught a German course for our medical doctors in everyday German helping them to acquire skills for communicating with their German speaking patients as well as managing the daily life. Her knowledge of the Chinese language and culture was helpful when communicating with the Chinese students. The students especially appreciated Ms Naef’s empathetic teaching style that made them feel very comfortable in class."

“Ms Katri Naef has taught a German class for my Chinese colleagues and me. We enjoyed studying with her, because she is a serious and competent language teacher. In addition to language skills we learned a lot about the Swiss culture and how to deal with daily matters and where to look for help when necessary.

Ms Naef’s intimate knowledge and great interest in the Chinese culture and language makes her an ideal teacher for Chinese people. I recommend her warmly to help your employees in getting familiar with the German language and the local customs of Switzerland."
