extraordinary teambuilding

Today, Tuesday 27.08.2019, a very special copmpany event was on the agenda for the team at our headquarters in Leun:

For a reportage on ZDF (German Television Program), a television team was in the historic city of Wetzlar, which is only a few kilometers away from our headquarters in Leun, and we were the group that received a guided tour of the city for the reportage. Together with managing director Ernst-Günter Ache, the employees as well as the ZDF team were guided through old alleys to the most beautiful corners of the district town on the river Lahn. Over the Kornmarkt and along the Mühlgraben there was a lot to see, which made for a great day for all participants.
