Ice hockey was the first sport he began working with and between 1969 and 1994 he represented the majority of the Swedish ice hockey players in NHL. Golf and tennis were other sports involving the agency during the 70s and 80s, with projects such as Team Siab and Team Saab as well as alpine skiing.
