He worked to create the excellent basis upon which the new managing board could build in 2012. In his 30 years in the industry, Theo Christen has experienced all manner of economic highs and lows, which makes him something of a living encyclopedia. The two “younger ones” – Florian Christen and Milot Shala – can rely on his knowledge for a while yet. He is happy to advise them when it comes to casting manufacturing and post-processing.
