Today, 2 months ago, we have built the ISH in Frankfurt ... We would like to thank you not only for the now 5-year collaboration, but in particular for the implementation of this year's ISH 2009 in Frankfurt. In planning your professional advice was an efficient support and enabled a smooth order of events by your flexibility. It was great fun to work with you ... Thank YOU, see you SOON!
Bobbie M. Preuß, WILO, Mai 2009
