Dominik Klein comes from a handball family and has learned club culture and teamwork from the ground up. He became handball world champion in 2007 and is an ARD handball expert. Together with Christian Emrich, he founded one of the first non-profit limited companies in German sport. They did this deliberately to ensure that every minute of voluntary work and every euro spent by children in the golden age of learning directly benefits them. Their vision: "Getting children excited about exercise".
