Oliver White:

I am Oliver White and I am from Halifax, England. I completed a Bachelor’s degree in Geography at the University of Manchester with a year abroad at the Universität Osnabrück in Germany. Since then, in a quest to not forget all the German I spent so much time learning, I started a European Masters in Global Studies that took me to Leipzig and then Vienna. After my Masters I worked in Vienna as a Native Speaker teacher, taught English at a refugee education center and coached a bit of football on the side. Now I have settled in Klagenfurt and it is anybody’s guess which hockey team I will ultimately support.
