I have been teaching Danish since the 1990's, both privately, for night schools and for Bang and Olufsen UK. I am currently the teacher of Danish at the MoD's language school and the resident Danish teacher at Klub Danmark in East Berkshire.

And from NS's Danish partner J:
"It's great to just go back to Denmark and enjoy the family without having to do the translating. There is no joy greater than being able to sit around a family table and discuss topical issues - in Danish!"
