Casey Mittelstadt Bio
Casey Mittelstadt is an American professional ice hockey player who plays the center position for the Boston Bruins of the National Hockey League (NHL). Selected in the first round, eighth overall, by the Buffalo Sabres in the 2017 NHL entry draft, he has developed into a dependable two-way forward known for his skating and playmaking. After spending most of his early career in Buffalo, Mittelstadt was traded to the Colorado Avalanche in March 2024 and later moved to the Boston Bruins in March 2025.
Born and raised in Minnesota, Mittelstadt rose to national attention as one of the top amateur players in the United States. He has represented his country in international competition and was named Most Valuable Player of the 2018 World Junior Ice Hockey Championships. Today, he continues his professional career as a top-six center in the NHL.
Early Life and Background
Casey Mittelstadt was born on November 22, 1998, in Edina, Minnesota. He grew up in the nearby community of Eden Prairie, where he developed his love for hockey at a young age. The Minneapolis–Saint Paul area has long been a hotbed for competitive youth hockey, and Mittelstadt benefited from the region’s strong training infrastructure and competitive playing environment.
He attended Eden Prairie High School, where he starred on the school’s hockey team and earned national recognition for his performances. In both 2016 and 2017, he was chosen as the ALL-USA Boys Hockey Player of the Year. In 2017, he was also named Mr. Hockey, an award given to the top high school senior hockey player in the state of Minnesota. These accomplishments made him one of the most highly regarded amateur prospects in the country heading into his draft year.
Path to Hockey
Mittelstadt’s path to the NHL began with a standout career in American youth and high school hockey. Following his dominant senior season at Eden Prairie, he committed to play collegiate hockey for the Minnesota Golden Gophers, one of the premier programs in the National Collegiate Athletic Association (NCAA). His decision to play in the NCAA allowed him to continue developing against top-level amateur competition before turning professional.
During the 2017–18 season, Mittelstadt played as a freshman forward for the Golden Gophers. He ranked second on the team and seventh among all NCAA freshmen with 30 points, a performance that earned him a place on the Big Ten All-Freshman Team. He was also selected as a finalist for the national Freshman of the Year award, finishing alongside Quinn Hughes and Mitchell Lewandowski. His strong college season convinced the Buffalo Sabres that he was ready to make the jump to professional hockey.
Casey Mittelstadt Career
Early Career (2018–2020)
On March 26, 2018, Mittelstadt opted to leave the University of Minnesota and signed a three-year, entry-level contract with the Buffalo Sabres. He made his NHL debut on March 29, 2018, against the Detroit Red Wings, recording an assist in the game. Less than a week later, on April 6, he scored his first career NHL goal in a 7–5 loss to the Tampa Bay Lightning.
Buffalo chose to keep Mittelstadt with the big club for the entire 2018–19 season rather than assign him to the American Hockey League. He recorded 12 goals and 13 assists for 25 points in 77 games. After a slow start to the 2019–20 campaign, the Sabres sent him to the Rochester Americans, their AHL affiliate, on December 15, 2019, to help him rediscover his game.
Buffalo Sabres Breakthrough (2020–2024)
Mittelstadt signed a one-year contract with the Sabres on December 23, 2020, before inking a longer-term deal on September 2, 2021. The new contract was a three-year agreement worth $7.5 million, signaling the team’s belief in his development. Over the next several seasons, he gradually grew into a more responsible two-way center, with the Sabres relying on his speed and skill in the middle of the ice.
In the final year of that contract during the 2023–24 season, Mittelstadt emerged as Buffalo’s top line two-way center. He led the club in scoring with 33 assists and 47 points through 62 regular season games, showing a level of consistency the Sabres had been waiting to see. However, with the team out of playoff contention, Buffalo opted to move on from the long-tenured center. On March 6, 2024, Mittelstadt was traded to the Colorado Avalanche in exchange for defenseman Bowen Byram, ending a seven-year run in Buffalo.
Colorado Avalanche Era (2024–2025)
Acquired to assume second-line center duties behind Nathan MacKinnon, Mittelstadt made his Avalanche debut on March 8, 2024, in a 2–1 overtime victory over the Minnesota Wild. Four days later, on March 12, he scored his first goal for Colorado in a 6–2 win over the Calgary Flames. He closed the regular season with 10 points in 18 games, providing important depth down the middle for the Avalanche.
Mittelstadt’s arrival also brought him his first taste of the Stanley Cup playoffs. He made his postseason debut in the opening round against the Winnipeg Jets and scored his first playoff goal in a 7–6 defeat on April 21, 2024. Across 11 playoff games, he produced 9 points, with all of them coming at even strength, tying him with Mikko Rantanen for the team lead in that category. After the Avalanche were eliminated in the second round by the Dallas Stars, Mittelstadt signed a three-year, $17.25 million contract extension on June 26, 2024.
Boston Bruins Era (2025–Present)
On March 7, 2025, Mittelstadt was part of a multi-player deal that sent him, along with Will Zellers and a second-round pick in the 2025 NHL entry draft, from Colorado to the Boston Bruins. In return, the Avalanche received Charlie Coyle and a fifth-round pick in the 2026 NHL entry draft. The move gave Mittelstadt a fresh opportunity to contribute on a new team in the Eastern Conference.
Stepping into a larger role on a Bruins team fighting for consistency, Mittelstadt made an immediate impact. He recorded an assist in his first game for Boston against the Tampa Bay Lightning on March 8, 2025, and followed that up with three points in his first three contests, including his first goal in the Black and Gold on March 13 against the Ottawa Senators. He finished the 2024–25 season with 15 goals and 25 assists in 81 total games split between the Avalanche and Bruins.

Although he is not a race car driver, Mittelstadt brings many similar qualities to his game. He is praised for his smooth, explosive skating, his ability to create offense through clean passing, and his responsible defensive play. As a center, he is trusted in key faceoff situations and on the penalty kill, blending offensive skill with the work ethic demanded by the position.
Notable Events and Milestones
One of the defining moments of Mittelstadt’s career came at the 2018 World Junior Ice Hockey Championships, where he led the United States to a bronze medal.
