Brett Ashley Cantwell is a former elementary school teacher and the wife of Philadelphia Eagles head coach Nick Sirianni.
Married since 2013, Brett has followed Nick through four cities and coaching stops over the course of his career, ultimately watching him lead the Eagles to victory in Super Bowl LIX.
Their relationship began with an unusual twist: Nick remembered meeting Brett at their apartment complex in Kansas City, but she genuinely did not remember him, and it took some convincing from her sister to give him a chance.
Brett Ashley Cantwell Biography
She was born on August 26, 1986, in Springfield, Missouri, to her parents, Brad and Debbie Cantwell.
Brett Ashley Cantwell grew up alongside her older brother, Justin, and older sister, Courtney, the same sister who would later play a key role in her relationship with Nick Sirianni.
Brett stayed close to home for much of her early life and education before beginning a career as an elementary school teacher.
Standing 5 feet 7 inches tall, she was working as a teacher in Kansas City, Missouri, when her life intersected with Nick’s at a time when neither of them could have predicted where his coaching career would eventually take them.
Nick Sirianni’s Wife
Brett Ashley Cantwell is the wife of NFL Coach Nick Sirianni. They first crossed paths at their shared apartment complex in Kansas City, where Nick was working as an offensive quality control coach for the Kansas City Chiefs.
Their first encounter, however, did not immediately lead anywhere. According to Brett, she did not remember meeting him at all.
However, Nick remembered her clearly and mentioned to a mutual acquaintance that he worked for the Chiefs, a detail Brett later said she did not particularly care about at the time.
It was Brett’s sister, Courtney, who ultimately moved things forward. Courtney took a liking to Nick and encouraged Brett to give him a chance.
Brett eventually agreed, and after their first date, Nick reportedly texted Courtney, saying simply, ‘Hey, it worked.’ The line has since become one of the most memorable details of their relationship.
The couple dated for two years before Nick proposed, and they married at Schweitzer United Methodist Church in Missouri in June 2013.
Shortly after their wedding, Nick was hired by the San Diego Chargers as an offensive quality control coach, and Brett decided to leave her teaching career to support his growing coaching journey.
She later told Colts.com in 2019 that leaving Kansas City was emotionally difficult because she loved both her job and her life there, but she loved Nick more and believed the move was worth it.
From San Diego, the family relocated again when Nick became offensive coordinator of the Indianapolis Colts, and then once more in January 2021, when he was hired as head coach of the Philadelphia Eagles, bringing the family to Moorestown, New Jersey, where they continue to live.
Brett has spoken about finding a strong sense of community among other NFL coaches’ wives, explaining that the shared experience of frequent relocations creates an immediate bond.
The couple now have three children together: son Jacob, born in 2015; daughter Taylor, born in 2017; and son Miles, born in 2020. The children are frequently seen alongside their father during postgame press conferences, often sitting on his lap, a familiar sight for Eagles fans.
Brett has maintained a private, low-profile lifestyle despite her husband’s high-profile career, choosing not to build a public media presence and instead focusing on raising their three children through the family’s many moves.
She was present for one of the biggest moments of Nick’s career at Super Bowl LIX in February 2025, when the Eagles defeated the Kansas City Chiefs, the same franchise where Nick began his NFL coaching career and where the couple first met.
Brett Ashley Cantwell Net Worth
Her net worth has not been publicly confirmed. Since stepping away from her teaching career to support Nick’s coaching career and raise their family, Brett Ashley Cantwell’s financial life has been closely tied to the family’s shared household finances rather than any separate source of income.
Her husband, Nick Sirianni’s net worth is estimated to be $10 million, built primarily through his NFL coaching salary, which has increased significantly since he became the Eagles’ head coach in 2021, particularly following the team’s Super Bowl LVII appearance and Super Bowl LIX victory.
