The African Refiners Association has used the interpreting services of Calliope since its inaugural AGM in 2006. The quality of the interpreting in a completely bilingual (English/French) forum was invaluable.
The whole experience the first year led us to book the services of Calliope for 2007, and now that the 2007 AGM is over we have already requested their time for 2008. I would not hesitate to recommend them to anyone.
