Sean McDermott Family: Meet His Wife Jamie and Their Kids

Sean McDermott spent years as one of the most recognizable figures on the Buffalo Bills sideline, but his life away from football has always centered heavily on his wife, Jamie McDermott, and their three children. Throughout his time in Buffalo, the McDermott family became connected not only with the Bills but also with several community causes that had personal meaning to them.

Sean and Jamie met long before his NFL coaching career reached its highest level. Their story began while they were students at the College of William & Mary, where Sean also played college football. They later married and became parents to three children, Maddie, Gavin and Kelly.

While Sean’s coaching career put him in front of millions of football fans, Jamie and their children generally maintained a quieter profile. Still, the family occasionally shared parts of their lives through charitable projects, particularly their work involving food allergy awareness and children’s health.

Who Is Sean McDermott’s Wife?

Sean McDermott’s wife is Jamie McDermott, née Hershberger.

Jamie has been part of Sean’s life since well before he became an NFL head coach. The couple met while attending the College of William & Mary in Virginia.

Their connection developed during their college years, when Sean was balancing academics with football.

Unlike her husband, Jamie has generally avoided building a highly public profile. Most football fans know her through her appearances with Sean at community events and through the family’s charitable efforts.

That relative privacy has remained consistent even as Sean’s coaching career brought the family into the national sports spotlight.

Rather than becoming a regular celebrity presence, Jamie has largely concentrated on family and the causes she and Sean support together.

How Did Sean and Jamie McDermott Meet?

Sean and Jamie first crossed paths as students at the College of William & Mary.

The university became an important place in Sean’s life for several reasons.

He played safety for the William & Mary football team while completing his education. His experience there eventually helped lay the groundwork for a coaching career that would take him across the NFL.

It was also where he met the woman he would eventually marry.

Their relationship therefore began before Sean had the demanding schedule and national attention associated with professional coaching.

That history has followed them throughout the different stages of his career.

Sean spent years working his way through assistant coaching positions before becoming a defensive coordinator and eventually receiving his opportunity to lead an NFL franchise.

Jamie was there throughout that gradual climb.

Sean and Jamie Have Three Children

Sean and Jamie McDermott are parents to three children, two daughters and a son.

Their children are Maddie, Gavin and Kelly.

When Sean became head coach of the Buffalo Bills in 2017, Maddie was around eight years old, Gavin was six and Kelly was still an infant.

That meant the move to Buffalo represented a major transition for the entire family rather than simply a new coaching job for Sean.

The children effectively grew up alongside their father’s years with the Bills.

As Sean became one of the most recognizable coaches in the league, Maddie, Gavin and Kelly experienced a very different version of him at home.

Sean has joked about that difference publicly.

In a 2022 interview, he explained that his children did not necessarily think having an NFL head coach for a father was particularly impressive.

Instead, they sometimes made fun of his familiar sideline habits, including his clapping and intense mannerisms.

For Bills fans, those behaviors were part of the Sean McDermott coaching image. For his children, they were simply things their dad did.

Family Life Stayed Important During His Bills Career

NFL coaching is an unusually demanding profession.

A head coach’s week can involve long hours at the team facility, film study, meetings, practices, travel, games and constant preparation for the next opponent.

That workload becomes even more intense during the playoffs.

For Sean, maintaining a connection with Jamie and their children had to happen alongside those responsibilities.

His family also experienced the emotional side of professional football.

The Bills became regular playoff contenders during Sean’s tenure, meaning each season brought enormous expectations.

Wins were celebrated publicly, while playoff disappointments were analyzed nationally.

At home, however, Sean was still a husband and father.

The McDermott children’s willingness to joke about their father’s sideline personality offers a small glimpse into how the family kept football fame in perspective.

Food Allergies Became a Personal Family Cause

One of the most meaningful causes associated with Sean and Jamie McDermott has been food allergy awareness.

Two of their children have dealt with serious food allergies.

That experience made the subject personal rather than simply another charitable project connected to an NFL team.

Sean and Jamie became involved in initiatives designed to support families managing allergies and special dietary requirements.

They worked with community organizations and local grocery stores on efforts involving food donations and allergy-friendly products.

For families living with serious food allergies, something as ordinary as buying groceries or eating away from home can require careful planning.

The McDermotts understood those challenges through their own experience as parents.

Their involvement helped bring additional attention to an issue affecting many families but one that can sometimes be underestimated by people who have never dealt with it directly.

Sean and Jamie Supported Children’s Health Initiatives

The McDermott family’s community work also extended into children’s healthcare.

Sean and Jamie made visits to Oishei Children’s Hospital during their years in Buffalo.

Hospital visits from sports figures can provide a welcome distraction for children dealing with difficult treatments, but the McDermotts’ involvement reflected a broader interest in family health issues.

Their work around food allergies was especially closely connected with their experiences as parents.

Rather than keeping those challenges completely private, they used their visibility to help raise awareness.

That community involvement became another part of the family’s connection with Western New York.

Sean’s role with the Bills may have brought them to Buffalo initially, but their activities outside football helped establish relationships beyond the stadium.

Who Is Sean McDermott?

Sean McDermott was born on March 21, 1974, in Omaha, Nebraska, and grew up in Pennsylvania.

After playing college football at William & Mary, he moved into coaching.

His NFL coaching career began with the Philadelphia Eagles, where he gradually worked through several defensive positions.

He eventually became the Eagles’ defensive coordinator.

After Philadelphia, Sean joined the Carolina Panthers and spent several seasons coordinating their defense.

His work in Carolina strengthened his reputation around the league and helped position him for a head coaching opportunity.

The Buffalo Bills hired McDermott as head coach in 2017.

He inherited a franchise that had not reached the playoffs since the 1999 season.

Buffalo reached the postseason during his first year, immediately ending that lengthy drought.

That achievement changed expectations around the franchise.

The Buffalo Years Changed the McDermott Family’s Life

Sean’s arrival in Buffalo became the defining professional chapter of his coaching career.

The Bills developed into regular postseason contenders, with quarterback Josh Allen emerging as the centerpiece of the offense.

Buffalo repeatedly competed near the top of the AFC.

For the McDermott family, those seasons also meant becoming deeply familiar with Western New York.

Jamie and the children were no longer simply following Sean from one assistant coaching job to another. Buffalo became home during a major period of their lives.

The family participated in community events and established connections with local organizations.

Maddie, Gavin and Kelly also grew older during those years.

By the time Sean’s tenure with Buffalo ended, his children were at very different stages of life from when he accepted the job in 2017.

Sean McDermott’s Departure From Buffalo

Sean’s time as Buffalo’s head coach eventually came to an end after another difficult postseason exit.

The Bills dismissed him following an overtime Divisional Round loss to Denver.

The decision closed a major chapter for both Sean and his family.

Although Buffalo consistently reached the postseason during much of his tenure, the team was unable to reach the Super Bowl.

That became increasingly significant as expectations surrounding the roster continued to rise.

For the McDermott family, however, leaving Buffalo meant more than the conclusion of a coaching position.

They had spent years becoming part of the community.

Jamie and Sean had supported local initiatives, their children had grown up there and the family had developed personal ties outside football.

Sean McDermott’s Family Remains Mostly Private

Despite Sean’s national profile, the McDermotts have generally avoided making their children public personalities.

Maddie, Gavin and Kelly occasionally appear in discussions about Sean’s family, but their everyday lives remain largely private.

Jamie has followed a similar approach.

She has participated in community events and supported charitable initiatives without attempting to turn her husband’s NFL fame into a separate public career.

That has created a clear distinction between Sean McDermott the football coach and Sean McDermott the husband and father.

Fans saw the intense coach pacing and clapping on the sideline.

His children saw the same mannerisms at home and apparently found them funny enough to tease him about them.

It is a simple detail, but it says plenty about the difference between public reputation and family life.

Sean McDermott’s Life With Jamie and Their Children

Sean McDermott’s family story began long before he became an NFL head coach.

He met Jamie while they were students at the College of William & Mary, and their relationship continued as his coaching career took him through Philadelphia, Carolina and eventually Buffalo.

Together, Sean and Jamie became parents to Maddie, Gavin and Kelly.

Their experiences raising children also influenced the causes they supported, particularly food allergy awareness and children’s health initiatives.

During Sean’s years with the Bills, the family became connected with the Buffalo community in ways that extended beyond football.

His coaching chapter in Buffalo eventually ended, but the family’s involvement in Western New York became part of the personal legacy they left behind.

For those interested in Sean McDermott’s wife and kids, Jamie, Maddie, Gavin and Kelly provide a look at the quieter side of a coach whose professional life was built around pressure, preparation and Sunday football.
