Yes, Keith does own a Laundry business, although the relevance of that, I do not know. His day to day time is taken up 100% with running the school and from what I have seen with the number of hours he is putting in, there would be little time for anything else.
Perhaps, some people on here should appreciate genuine enterprise and not pour disdain on it.
I thought I would provide an update on the school's legality issue. With effect from the beginning of September, the school in addition to the English Curriculum, will also be offering examinations/study towards the Spanish Bacc. To do this the school has to be licensed with the Valencian Education Authorities and this process will be completed shortly.
