Early Life and Education of Mark Kastelic
Mark Kastelic was born on March 11, 1999, in Phoenix, Arizona, into a family deeply rooted in professional hockey. From a young age, the sport was an integral part of his life, not just as a passion but as a family tradition. His father, Ed Kastelic, had a notable NHL career with the Washington Capitals and Hartford Whalers, providing Mark with a firsthand look at the dedication required to compete at the highest level. The hockey influence extended even further, with his maternal grandfather being the legendary Pat Stapleton, a standout defenseman for the Chicago Blackhawks and Boston Bruins, and a member of Team Canada in the iconic 1972 Summit Series. His uncle, Mike Stapleton, also enjoyed a long career in the NHL. Growing up in this environment, Kastelic was immersed in hockey culture, learning the nuances of the game from his accomplished relatives. He spent his formative years in Arizona, where his parents, Ed and Susan, settled after his father’s playing career. He played his youth hockey with the Phoenix Jr. Coyotes, honing his skills while attending Desert Vista High School. Though he played other sports like soccer and track, his focus was always on making it to the NHL, a dream he pursued with singular determination, forgoing a potential college hockey path to play major junior hockey.
Mark Kastelic’s Career
Mark Kastelic’s path to the National Hockey League was a testament to his perseverance and development. His junior career began after the Calgary Hitmen of the Western Hockey League (WHL) drafted him 41st overall in the 2014 WHL Bantam Draft. He joined the Hitmen for the 2015-16 season and spent five full seasons with the club, steadily improving his game and growing into a leadership role. Initially overlooked in the 2017 and 2018 NHL Entry Drafts, Kastelic used the snubs as motivation. His breakout season came in 2018-19, when, as team captain, he erupted for 47 goals and 30 assists for 77 points in 66 games. This stellar performance as an over-age player finally caught the attention of NHL scouts, and the Ottawa Senators selected him in the fifth round, 125th overall, in the 2019 NHL Entry Draft. He returned to the Hitmen for a final season in 2019-20, once again serving as captain and continuing his productive play with 38 goals and 68 points in 58 games before the season was cut short by the COVID-19 pandemic.
Kastelic signed a three-year, entry-level contract with the Senators in April 2020 and turned professional for the 2020-21 season, joining Ottawa’s American Hockey League (AHL) affiliate, the Belleville Senators. In his first professional season, he recorded 10 points in 31 games. He took a significant step forward in the 2021-22 season, improving his output to 28 points in 64 games with Belleville and establishing himself as a physical, reliable center. His hard work paid off when he earned his first NHL recall, making his debut with the Ottawa Senators on January 29, 2022, against the Anaheim Ducks. He would later score his first two NHL goals, including the game-winner, on April 23, 2022, against the Montreal Canadiens. By the 2022-23 season, Kastelic had secured a full-time role with Ottawa, praised by the coaching staff for his work ethic and physical presence. His strong play led to a two-year contract extension in October 2022. He played 144 regular-season games for the Senators over parts of three seasons.
A significant new chapter in his career began on June 24, 2024, when Kastelic was traded to the Boston Bruins. He was part of a major deal that sent goaltender Linus Ullmark to Ottawa in exchange for Kastelic, goaltender Joonas Korpisalo, and a first-round draft pick. Joining the Bruins was particularly meaningful for Kastelic, as it was the same organization his grandfather, Pat Stapleton, played for early in his career. Kastelic quickly endeared himself to the Bruins with his tough, energetic style of play, becoming a key component of their fourth line. His immediate impact and gritty performance were rewarded on January 3, 2025, when the Bruins signed him to a three-year contract extension worth $4.7 million.
