Johann Darie (Coach)
...completed his First State Examination at Humboldt University of Berlin, having spent his specialisation abroad at King's College London. He studied on a scholarship from the Konrad Adenauer Foundation and is currently pursuing a PhD in international arbitration at Humboldt University.
He caught the arbitration bug during his studies in London during his time as a Vis Mootie – and he never quite got over it. Today, he’s back on the pitch as a coach. Professionally, Johann is involved in arbitration proceedings as a research assistant at a large German law firm. In addition, he supports a Member of the German Bundestag.
Outside of work, Johann volunteers with a winter relief programme for homeless people and was a member of the foundation’s “Senkrechtstarter” initiative, which mentors first-generation students and young people with a migration background. Whenever he can escape his desk, you can find him either on his motorbike on trips across Europe and beyond (or, quite often, on a train).
