Alex Vlasic Bio
Alex Vlasic, born on June 5, 2001, is an American professional ice hockey player who plays as a defenseman for the Chicago Blackhawks of the National Hockey League (NHL). Standing 6 feet 6 inches tall, he uses his size and skating ability to anchor the Blackhawks’ blue line. Drafted 43rd overall by Chicago in the 2019 NHL Entry Draft, he joined the franchise after a three-year collegiate career at Boston University and has since developed into one of the team’s most relied-upon defensemen.
Vlasic is of Croatian descent and grew up in Wilmette, Illinois, where he first learned to skate as a young child. He later represented the United States at the international level, helping the program claim its first gold medal in nearly a century. He continues to play for the Chicago Blackhawks under a long-term contract.
Early Life and Background
Alex Vlasic was born on June 5, 2001, in Wilmette, Illinois, to parents Tara and John. He grew up alongside his older siblings, Emma and Eric, in a family with strong ties to the sport of ice hockey. His grandfather immigrated to Montreal, giving the family Croatian heritage that has remained part of Vlasic’s identity.
Although he grew up in Illinois, Vlasic became a fan of the San Jose Sharks because of his cousin Marc-Édouard Vlasic, who played for the franchise. He began skating at the age of three and joined the Wilmette Braves, playing at the Mite, Squirt, and Pee Wee levels. Both of his siblings were also involved in hockey: Emma played at Yale University and with the Connecticut Whale, while his brother participated in the Chicago Blackhawks special hockey program. Vlasic played as a forward until the age of nine, when he switched to defense, a change that shaped his future as an NHL defenseman.
At the age of 13, Vlasic was diagnosed with celiac disease, an experience he has spoken about as part of his personal journey. His early years in Wilmette and his family’s hockey background gave him a steady foundation as he began climbing the youth ranks.
Path to Hockey
While growing up in Illinois, Vlasic played for the Chicago Young Americans and the Chicago Mission, two well-known youth programs in the region. While with the Chicago Mission’s Midget U16 team, he committed to playing college ice hockey at Boston University. At the time of his commitment, he was also considered a top-five prospect for the Ontario Hockey League, making his decision to pursue the NCAA path a notable one.
Instead of joining the OHL, Vlasic was recruited to play for the USA Hockey National Team Development Program for the 2017–18 United States Hockey League season. He later credited the program’s intense and fast-paced practices with improving his game, along with the support of the under-17 coaching staff, including John Wroblewski and Greg Moore. He also praised the addition of Dan Hinote as an associate head coach for helping him build strength and muscle.
These developmental years gave Vlasic the structure and competition needed to prepare for collegiate hockey. By the time he finished with the National Team Development Program, he was widely viewed as one of the top defensive prospects heading into the 2019 NHL Entry Draft.
Alex Vlasic Career
Early Career (2019–2022)
Vlasic played three seasons with the Boston University Terriers while enrolled in the Boston University College of Arts and Sciences. Following his selection by the Chicago Blackhawks in the second round of the 2019 NHL Entry Draft, he reaffirmed his commitment to play college hockey.

When the season was cut short by the COVID-19 pandemic, Vlasic and his sister built a makeshift weight room in their basement and skated at a local rink. He also worked on his skills with Tristan Musser of the Chicago Steel and Brian Keane, who owns Prodigy Hockey. During the 2020–21 season, he recorded his first collegiate multi-point game on January 23, 2021, in a 5–1 win over the University of Maine, and scored his first collegiate goal on February 5 against Boston College.
Boston University Breakthrough (2021–2022)
The following season, Vlasic became one of the best defensive defensemen in Hockey East and was praised by his head coach for being an elite skater for his size. He led the team with 50 blocked shots and tallied one goal and a career-high seven assists for eight points. His strong two-way play earned him Hockey East All-Star honors and helped position him as a top prospect ready for the professional ranks.
Chicago Blackhawks Era (2022–Present)
Vlasic signed a three-year entry-level contract with the Chicago Blackhawks on March 15, 2022, after concluding his college career.
