William Stromgren

Growing up in Örnsköldsvik, William Strömgren learned his hockey in a community steeped in the sport. He honed his skating and offensive instincts there before moving through local junior ranks and into Sweden’s professional tiers as a teenager. His left-wing profile and mobility caught attention early on.

Strömgren stepped into pro hockey in 2020-21 with Modo Hockey of HockeyAllsvenskan, dividing that season between the senior squad, Modo’s junior sides and a loan stint at Örnsköldsvik HF in HockeyEttan. After his performances at junior level and internationally, Calgary selected him in the 2021 NHL Draft, taking him in the second round, 45th overall.

He made his SHL debut with Rögle BK during 2021-22 but struggled to secure a steady spot on the top roster and spent much of the campaign with Rögle’s junior team. Early in 2022-23 he and Rögle agreed to terminate his contract, and he signed with Brynäs IF. That move allowed him a larger role: he dressed in 45 games for Brynäs that season, gaining consistent top-level ice time.

Calgary signed Strömgren to a three-year entry-level contract on 29 March 2023, effective with the 2023–24 season. He immediately joined the Flames’ AHL affiliate, the Calgary Wranglers, on an amateur-tryout and appeared in two late-season games. During the Flames’ 2023 preseason Young Stars Classic he scored twice against the Winnipeg Jets; cut early from NHL camp, he was assigned to the Wranglers on 29 September 2023. His first AHL goal came on 23 December 2023 in a 5–1 win over the Colorado Eagles, in his 24th AHL game.

Internationally, Strömgren helped Sweden win bronze at the 2021 IIHF U18 Championship, recording two goals and three assists. He also represented Sweden at the 2023 World Junior Championship, appearing in seven games and registering one assist as the team lost the bronze medal game to the United States. On the ice he is an offensive-minded winger who combines skating and playmaking ability to contribute in various forward roles.
