William Strömgren Bio
William Strömgren is a Swedish ice hockey left-winger born on June 7, 2003, in Örnsköldsvik, Sweden. He plays for the Calgary Wranglers of the American Hockey League (AHL), where he develops as a prospect for the Calgary Flames of the National Hockey League (NHL). Standing 191 centimeters tall and weighing 82 kilograms, Strömgren began his professional career as a teenager in Sweden before being selected by the Flames in the 2021 NHL Draft.
A product of the Swedish development system, Strömgren has represented his country at multiple IIHF youth tournaments and continues his progression through North American professional hockey with the Flames organization.
Early Life and Background
William Strömgren was born and raised in Örnsköldsvik, a northern Swedish city known for its strong ice hockey tradition. The community has produced several Swedish hockey talents, and Strömgren grew up immersed in the sport from an early age, eventually joining the local junior ranks and working his way up through the development pathway associated with Modo Hockey.
Standing 191 centimeters tall, Strömgren developed the frame of a modern power forward, a physical attribute that has complemented his skill set as he transitioned into professional hockey. His time in the junior leagues of Sweden helped him build the foundation needed for a career in the sport.
Path to Hockey
Strömgren began his professional career during the 2020-21 season with Modo Hockey, playing in the second-tier HockeyAllsvenskan. That season, he split his time between MoDo’s junior teams and a loan spell with Örnsköldsvik HF of the third-tier HockeyEttan, gaining valuable senior minutes alongside continued junior development.
His strong play and projection as a prospect led to his selection by the Calgary Flames in the second round, 45th overall, of the 2021 NHL Draft. Following the draft, he returned to Sweden to continue developing at the top professional level, eventually making the jump to North America after three Swedish campaigns.
William Strömgren Career
Early Career (2020-2022)
Following his draft, Strömgren made his Swedish Hockey League (SHL) debut with Rögle BK during the 2021-22 season. However, he struggled to secure a consistent roster spot at the top level, spending most of the season with Rögle’s junior club while adjusting to the demands of senior hockey in Sweden’s premier league.
Early in the 2022-23 season, Strömgren mutually terminated his contract with Rögle, a club that had won the SHL championship the previous year, and joined Brynäs IF. The move provided him with a more prominent role, as he suited up for 45 games with Brynäs and showed growth as an everyday contributor.
SHL and Brynäs IF Breakthrough (2022-2023)
At Brynäs IF, Strömgren took on a larger offensive role and logged significant ice time across a full campaign. The experience of playing 45 games in the SHL allowed him to refine his two-way game and adapt to the pace and physicality of top-flight Swedish hockey.
His progression at Brynäs helped solidify his standing as a legitimate NHL prospect, paving the way for his eventual contract with the Calgary Flames in March 2023.
Calgary Flames Organization Era (2023-Present)
On March 29, 2023, the Calgary Flames signed Strömgren to a three-year entry-level contract beginning with the 2023-24 season. He then signed an amateur tryout agreement with the Flames’ AHL affiliate, the Calgary Wranglers, joining late in the 2022-23 campaign and appearing in two games to close out the year.
During the Flames’ 2023 preseason, Strömgren participated in the Young Stars Classic tournament and scored twice against the Winnipeg Jets’ prospects. After being assigned to the Wranglers on September 29, 2023, he scored his first AHL goal on December 23, 2023, in a 5-1 victory over the Colorado Eagles, marking his 24th game of the season.

Strömgren is a left-winger listed at 191 centimeters and 82 kilograms, giving him the size to drive play along the boards and win puck battles.
