Former Calgary Flames Captain Mark Giordano Named Assistant Coach of Toronto Marlies
Mark Giordano, former captain of the Calgary Flames, has been appointed as an assistant coach for the Toronto Marlies for the upcoming 2026-27 American Hockey League season. This move sees Giordano transition from an advisory role within the organization to a coaching position.
Giordano will join the coaching staff led by newly appointed head coach Steve Sullivan. The team’s coaching roster also includes goaltending coach Hannu Toivonen and video coach Nick Biamonte.
Giordano’s Extensive Playing Career
Giordano’s playing career in the National Hockey League was notable, particularly his tenure with the Flames. He captained the team from 2013 to 2021, taking over the leadership role from Jarome Iginla. During his 15 seasons in Calgary, Giordano participated in 949 regular-season games, placing him third in the franchise’s history for appearances. He established himself as one of the organization’s most accomplished defencemen during this period.
His time with the Flames concluded when he was selected by the Seattle Kraken in the 2021 NHL Expansion Draft. He was named the inaugural captain for the Kraken franchise. Following his stint with Seattle, Giordano joined the Toronto Maple Leafs, where he played for three seasons before announcing his retirement in 2024.
Giordano, a Toronto native, experienced a career-best offensive season in 2018-19. During that season, he recorded 17 goals and 57 assists, accumulating 74 points, and achieved a plus-39 rating. His performance that year earned him the James Norris Memorial Trophy, recognizing him as the NHL’s top defenceman. Additionally, in 2019-20, Giordano was awarded the Mark Messier NHL Leadership Award, an honour presented annually to a player who demonstrates leadership on and off the ice, makes a positive community impact, and contributes to the growth of hockey.
New Coaching Staff for the Marlies
The appointment of Giordano as assistant coach comes as part of a broader restructuring of the Marlies’ coaching staff. Steve Sullivan has been named the new head coach of the Marlies. Sullivan had previously served as an assistant coach with the Marlies before being elevated to the Maple Leafs on December 26, 2025. He initially joined the organization prior to the 2024-25 season.
Prior to his roles in Toronto, Sullivan held the position of assistant general manager for the Arizona Coyotes from 2017 to 2021. In this capacity, he oversaw the club’s AHL affiliate, the Tucson Roadrunners. His experience in Arizona also included working in the hockey operations department as a development coach and later as the director of player development.
As a player, Sullivan’s NHL career spanned 16 seasons, during which he played in 1,011 regular-season games. His NHL teams included New Jersey, Toronto, Chicago, Nashville, Pittsburgh, and Arizona. He also played 143 games in the American Hockey League, where he won a Calder Cup with the Albany River Rats in 1995 and participated in two AHL All-Star Classics.
Sullivan expressed confidence in Giordano’s capabilities, stating that Giordano is an “elite hockey mind” who will have a significant opportunity to manage the defence and penalty kill aspects of the team. This new coaching lineup aims to further develop players within the Marlies organization.
The Marlies recently won the Calder Cup, and the organization is focused on maintaining a strong pipeline for the Maple Leafs. Sullivan emphasized that the AHL exists to help the main NHL team succeed, and that player development encompasses on-ice skills, off-ice conduct, and personal growth. He highlighted that while some players, like a potential Gavin McKenna, might transition directly to the NHL, others may require more time for development in the AHL.
Sullivan also discussed the shift in his responsibilities, moving from a specialized assistant role to overseeing an entire operation. He plans to empower his staff, including coaches, equipment managers, strength and conditioning personnel, and medical staff, to manage their respective departments. He cited his own experience with John Gruden, who gave him autonomy with the power play, as an example of the approach he intends to take.
This new coaching structure for the Toronto Marlies is set for the 2026-27 American Hockey League season.
