Sean Monahan is a Canadian professional ice hockey player who plays as a center for the Columbus Blue Jackets in the National Hockey League (NHL). Born on October 12, 1994, in Brampton, Ontario, Canada, Monahan grew up in a supportive family that helped him develop into one of the NHL’s established forwards.
His family includes his wife, Brittany Monahan, their son, Leo Monahan, his parents, John and Cathy Monahan, and his older sister, Jacqueline Monahan.
Family has been central to Monahan’s life, particularly during his transition to professional hockey and the emotional challenges he experienced following the death of his close friend and former teammate Johnny Gaudreau.
Sean Monahan’s Wife: Is He Married or Dating?
Sean Monahan is married to Brittany Monahan, his longtime romantic partner.
Although the Columbus Blue Jackets forward generally keeps his relationship private, Brittany has been identified as his wife in official NHL publications, interviews, and media coverage.
The couple have shared several important milestones, including welcoming their first child in May 2024 and relocating to Columbus, Ohio, following Monahan’s signing with the Blue Jackets.
In an NHL Players’ Association interview published in 2024, Monahan spoke enthusiastically about beginning a new chapter in Columbus with Brittany and their newborn son.
He explained that becoming a father had changed his perspective on life and that he was excited to raise his son in a community close enough for extended family members to visit.
Brittany has also supported her husband during difficult periods in his career, including following the death of his best friend, Johnny Gaudreau, in August 2024.
In June 2025, Brittany helped arrange a surprise ceremony in which Meredith Gaudreau presented Monahan with the Bill Masterton Memorial Trophy.
Although the couple’s marriage is publicly confirmed, reliable sources have not widely documented their exact wedding date, where they first met, or details of their wedding ceremony.
Sean Monahan’s Children
Sean Monahan and his wife, Brittany, have one publicly confirmed child, a son named Leo Monahan.
Leo was born on May 27, 2024, shortly before Sean signed with the Columbus Blue Jackets.
Leo Monahan: Sean Monahan’s Son
Leo Monahan is the first child of Sean and Brittany Monahan.
His birth marked an important personal milestone for the NHL player, who has spoken openly about the happiness and responsibility of fatherhood.
In a September 2024 interview with the NHL Players’ Association, Monahan described becoming a father as an experience that gave him a new perspective on life.
The family subsequently relocated to the Columbus area, where Leo spent his early childhood.
One particularly meaningful connection developed between Leo and the children of Sean’s longtime friend Johnny Gaudreau.
According to a November 2024 Sportsnet report, Leo regularly spent time with Gaudreau’s son, Johnny Jr., who is approximately three and a half months older.
The families lived close to each other in the Columbus area and maintained a strong relationship following Gaudreau’s death.
In June 2025, Monahan shared another milestone when he revealed that Leo had recently taken his first steps.
During an interview with the Columbus Blue Jackets, Sean explained that spending time with his wife, son, and family dog helped him cope with grief and the challenges of professional hockey.
There have been no reliable public announcements confirming additional children.
Sean Monahan’s Parents
Sean Monahan was born to John Monahan and Cathy Monahan, who raised him and his older sister, Jacqueline, in Brampton, Ontario.
Both parents played important roles in his childhood, encouraging him to pursue hockey while emphasizing discipline, responsibility, and hard work.
Sean Monahan’s Father: John Monahan
John Monahan is Sean’s father and one of the earliest influences on his hockey career.
John helped introduce Sean to hockey when he was approximately three years old.
According to a 2013 profile published by FlamesNation, Sean was initially a shy child who preferred having his father nearby during practices.
He frequently asked John to stay on the bench or coach him because he felt more comfortable with his father’s presence.
As Sean became more competitive, John continued encouraging him to develop strong habits, particularly when handling the puck and competing against other players.
John emphasized the importance of commitment, discipline, and earning respect through consistent effort.
In October 2013, he traveled to Washington, D.C., to watch Sean make his NHL debut for the Calgary Flames against the Washington Capitals.
John also attended important events throughout his son’s junior hockey career.
In April 2025, The Athletic reported that John and Cathy were preparing to travel with Sean’s family from Ontario to Columbus when they learned about Johnny Gaudreau’s death.
The report demonstrated how closely Sean’s parents remained involved in his life even after he had established himself as an NHL veteran.
Sean Monahan’s Mother: Cathy Monahan
Cathy Monahan is Sean’s mother and another important figure in his upbringing.
According to an October 2013 interview published by the Ottawa 67’s, Cathy worked as a special-needs educational aide at a school in Ontario.
She supported Sean throughout his minor and junior hockey development, attending games and encouraging him to pursue his ambitions.
Cathy played a particularly important role during Sean’s rookie season with the Calgary Flames.
When Monahan secured a permanent position with Calgary in the 2013–14 NHL season, he was only 19 years old and living far from his family in Ontario.
Rather than leaving him to manage his first professional season alone, Cathy temporarily moved to Calgary to live with him.
Her presence helped Sean adjust to the responsibilities and expectations of being an NHL player.
In February 2014, Monahan told The Canadian Press that having his mother nearby made the transition easier because he remained very close to his family.
Cathy also provided practical support by preparing meals and helping him maintain a stable daily routine.
In a January 2017 Calgary Flames feature, Monahan recalled how much he appreciated his mother’s cooking during his rookie season.
Her encouragement and willingness to relocate demonstrated the significant sacrifices his family made to support his professional development.
Cathy has continued to be present during important moments in Sean’s career, including family gatherings and celebrations following his move to Columbus.
Sean Monahan’s Siblings
Sean Monahan has one older sister named Jacqueline Monahan.
Her identity is confirmed by Hockey Canada’s official player biography and a 2013 Ottawa 67’s feature about Sean’s early NHL career.
Jacqueline Monahan: Sean Monahan’s Older Sister
Jacqueline Monahan is Sean’s older sister and the daughter of John and Cathy Monahan.
She grew up alongside Sean in Brampton, Ontario, where the family shared an interest in sports.
Jacqueline was part of the family support system that encouraged Sean throughout his development as a hockey player.
In October 2013, the Ottawa 67’s reported that Jacqueline traveled with her parents from Brampton to Calgary to spend time with Sean during the early stages of his NHL career.
Her presence was particularly meaningful because Sean was adjusting to life away from home after being drafted by the Calgary Flames.
In April 2019, Sportsnet featured Sean alongside his parents and sister in a segment highlighting the role family support played in helping him achieve his NHL ambitions.
Although Jacqueline has appeared in family-related hockey coverage, she generally maintains a private life.
Reliable details about her age, occupation, marital status, and children have not been widely disclosed.
Does Sean Monahan Have a Brother?
Sean Monahan does not have a publicly documented brother.
Hockey Canada’s official biography identifies Jacqueline as his only sibling.
However, Sean developed a brother-like friendship with fellow NHL player Johnny Gaudreau during their years together with the Calgary Flames.
Their friendship remained important even after they joined different teams.
Sean Monahan’s Extended Family and Hockey Background
Sean Monahan comes from a family with connections to competitive hockey.
According to a 2013 FlamesNation profile, his grandfather played for the Pittsburgh Hornets in the American Hockey League (AHL).
The same article reported that one of Sean’s uncles played professional hockey in Italy, while a cousin pursued professional hockey in Germany.
These family connections helped expose him to the sport from a young age.
Although hockey eventually became Sean’s profession, he also enjoyed lacrosse during childhood.
In January 2024, the Montreal Canadiens published an interview in which Monahan discussed growing up in a family that played lacrosse.
He participated in minor hockey and lacrosse while attending school in Brampton.
His athletic upbringing helped develop the competitiveness and determination that later became important parts of his NHL career.
How Sean Monahan’s Family Supported His Hockey Career
Sean Monahan began playing hockey at approximately three years old and progressed through minor hockey programs in the Greater Toronto Area.
In 2010, he helped the Mississauga Rebels win the OHL Cup before joining the Ottawa 67’s of the Ontario Hockey League.
He played three seasons with Ottawa, eventually becoming the team’s captain and one of its leading scorers.
In the 2013 NHL Entry Draft, the Calgary Flames selected Monahan sixth overall.
His parents and sister supported him as he moved to Calgary and established himself in the NHL.
After nine seasons with the Flames, Monahan joined the Montreal Canadiens in 2022 and was later traded to the Winnipeg Jets in 2024.
On July 1, 2024, he signed a five-year contract with the Columbus Blue Jackets.
The move was particularly meaningful because it brought him closer to his family in Ontario and offered an opportunity to reunite with his close friend Johnny Gaudreau.
However, Gaudreau and his brother Matthew tragically died in August 2024 after being struck by a vehicle while cycling in New Jersey.
The loss deeply affected Monahan, who subsequently credited his wife, son, parents, teammates, and the Gaudreau family with helping him navigate his grief.
In June 2025, he received the Bill Masterton Memorial Trophy, recognizing perseverance, sportsmanship, and dedication to hockey.
During the award presentation, Monahan expressed appreciation for the support he had received from his family and teammates.
