What began in 1966 on 25 m² in a former bird shop in Baden near Vienna has long since taken flight and left national borders far behind: we started out small, but in recent decades we have developed into the largest local congress organization office, which is now active throughout Europe.


A lot has happened in the last decades – here are some milestones:


  • 1966 The company was founded by Rudolf Kadanka in a former bird shop, initially as a two-man business
  • 1977 Entry of Annette Jirasek, the longtime head of Mondial Congress & Events. She is still active in management and in shaping the department.
