Mike Sullivan is an American professional ice hockey coach and former NHL player who serves as the head coach of the New York Rangers. Born on February 27, 1968, in Marshfield, Massachusetts, he comes from a close-knit Irish-American family with a strong passion for sports.
Sullivan is married to his longtime partner, Kate Sullivan, a former nurse whom he met during high school. The couple married in 1991 and have three children: Kaitlin Sullivan, Matthew Sullivan, and Kiley Sullivan, who is married to Boston Bruins defenseman Charlie McAvoy.
His parents were George Sullivan and Myrna Sullivan, and he grew up with four siblings: George, Kathie, Deborah, and Brian Sullivan. His father worked in banking and coached youth sports, while his mother was a nurse.
Mike Sullivan’s Wife: Kate Sullivan
Mike Sullivan is married to Kate Sullivan, his high school sweetheart and longtime partner.
The couple met while attending high school in Massachusetts and maintained their relationship as Mike pursued collegiate and professional ice hockey.
When Mike enrolled at Boston University to play hockey, Kate attended Boston College, where she studied nursing.
The couple married in 1991 and subsequently built a family while navigating the demands of Mike’s professional playing and coaching careers.
Kate pursued a career in nursing, working in different medical specialties, including oncology and pediatric medicine.
During Mike’s eleven seasons as an NHL player, Kate balanced her professional responsibilities with raising their three children.
Her support continued when Sullivan transitioned into coaching, eventually becoming one of the NHL’s most successful head coaches.
Kate Sullivan’s Nursing Career
Kate Sullivan followed a professional path similar to that of Mike’s mother, Myrna Sullivan, who also worked as a nurse.
According to a May 2021 interview published by the Pittsburgh Post-Gazette, Kate had been interested in nursing since she was young.
After completing her education at Boston College, she worked in several healthcare settings.
Her responsibilities included caring for patients receiving cancer treatment and working in pediatric medicine.
Kate eventually stepped away from professional nursing after Mike became head coach of the Pittsburgh Penguins in December 2015.
However, her commitment to healthcare remained strong.
During the COVID-19 pandemic, she considered volunteering to help administer vaccinations but ultimately decided against it because of the potential health risks to her family and the Penguins organization.
In interviews, Mike has praised his wife’s compassion, dedication, and willingness to help others.
Kate Sullivan’s Support for Mike’s Coaching Career
Kate has been an important source of emotional support throughout her husband’s coaching career.
Professional hockey coaching involves demanding schedules, frequent travel, and considerable pressure, particularly during the Stanley Cup Playoffs.
During Mike’s years with the Pittsburgh Penguins, Kate helped maintain family stability while he managed the responsibilities of leading an NHL team.
She was also closely involved in family gatherings during Pittsburgh’s Stanley Cup championship celebrations in 2016 and 2017.
In a 2017 interview with the Pittsburgh Post-Gazette, Mike’s father, George, discussed the hospitality Kate extended to him during the Penguins’ playoff runs.
George stayed with Mike and Kate throughout both championship runs and praised the care he received from the family.
Mike Sullivan’s Children
Mike Sullivan and his wife, Kate, have three children: two daughters, Kaitlin and Kiley, and a son named Matthew.
Their children’s identities are confirmed by the Vancouver Canucks’ official coaching biography and a 2021 Pittsburgh Post-Gazette family feature.
Kaitlin Sullivan – Daughter
Kaitlin Sullivan is one of Mike and Kate Sullivan’s two daughters.
She grew up in a family deeply involved in professional hockey, experiencing the challenges and opportunities associated with her father’s playing and coaching careers.
Kaitlin is identified in official hockey biographies and family records, including the 2013–14 Vancouver Canucks media guide.
However, she generally maintains a private personal life.
Her current occupation, marital status, and other personal details have not been extensively documented in major public sports publications.
Matthew Sullivan – Son
Matthew Sullivan, also known as Matt Sullivan, is Mike Sullivan’s son.
Like his father, Matthew pursued competitive ice hockey during his youth and college years.
He attended Bowdoin College in Maine, where he played collegiate hockey.
In a March 2022 feature published by DK Pittsburgh Sports, Mike discussed how his work with the Chicago Blackhawks organization during the 2014–15 season allowed him to spend more time with his family.
Because his development coaching responsibilities involved a flexible schedule, he had opportunities to watch Matthew compete for Bowdoin.
Mike described those experiences as especially meaningful because the demands of NHL coaching often limited his ability to attend family events.
Matthew’s involvement in hockey continued the family’s sporting tradition established by his grandfather, George Sullivan.
Detailed information about Matthew’s later professional activities and personal relationships has not been widely documented.
Kiley Sullivan – Daughter
Kiley Sullivan, now known as Kiley McAvoy, is Mike Sullivan’s daughter and the wife of Boston Bruins defenseman Charlie McAvoy.
Kiley attended Boston University, where she earned a degree in health science in 2019.
She later pursued nursing, following the professional paths of her mother, Kate Sullivan, and paternal grandmother, Myrna Sullivan.
In 2022, she earned a nursing degree from the MGH Institute of Health Professions in Boston.
Kiley met Charlie McAvoy through mutual friends while they were students at Boston University in 2015.
The couple began dating that December and eventually became engaged during a trip to Capri, Italy, in 2022.
They married on August 5, 2023, at Marsh Chapel at Boston University, followed by a reception at the Boston Public Library.
The marriage created another connection between the Sullivan family and professional hockey.
Mike became the father-in-law of Charlie McAvoy, one of the Boston Bruins’ leading defensemen.
Mike Sullivan’s Grandchildren
Mike Sullivan is also a grandfather.
His daughter Kiley and son-in-law Charlie McAvoy welcomed a son named Rhys Michael McAvoy on January 26, 2025.

The identity of Sullivan’s other grandchild has not been widely documented in the major public sources reviewed.
Rhys Michael McAvoy – Grandson
Rhys Michael McAvoy is the son of Kiley Sullivan McAvoy and Charlie McAvoy.
His birth was particularly meaningful because it occurred shortly before Charlie and Mike worked together with the United States men’s national hockey team at the 2025 4 Nations Face-Off.
In an interview published by the Associated Press in February 2025, Sullivan described the happiness of becoming a grandfather.
He also expressed appreciation for the opportunity to coach his son-in-law while representing the United States internationally.
That family connection became even more memorable when Sullivan coached the United States to a gold medal at the 2026 Winter Olympics.
Charlie McAvoy was a member of the championship-winning American team, giving the family a shared international hockey achievement.
