Helsingborg Basket in his native Sweden before making his debut in the country's second-tier league
Basketettan in the early stages of the 2015–16 season. He had a tremendous presence inside in terms of blocking shots (5.8 bpg) in Basketettan play, while averaging 11.7 points and 13.5 rebounds per contest (12 games played). Birgander left Sweden in January 2016 to head to Spain, where he joined
