David Grant worked for 8 years with the International House in France, Spain, and England, as a teacher, teacher trainer, and Director of Studies. In 1990 he moved to Nantes in the west of France, where he opened his own private training organization, International Language Services. The school offers custom-built courses in Business English and ESP to local companies. David still spends much of his time in the classroom, which he regards as an essential source of ideas for his writing.

David is the co-author of Quick Work Elementary and Business Basics, both published by Oxford University Press.
