Kroy Evan Biermann, born on September 12, 1985, in Hardin, Montana, is an American former professional football player best known for his seven-season tenure as a linebacker with the Atlanta Falcons of the National Football League (NFL). While his athletic career was marked by consistent defensive production, Biermann became a household name beyond the gridiron through his high-profile marriage to reality television star Kim Zolciak and their family's appearances on the hit Bravo series Don't Be Tardy. His life story weaves together small-town Montana roots, a determined rise through college football, and a second act defined by reality TV fame and personal challenges.

Growing up in Montana, Biermann attended Poplar High School, where he excelled in multiple sports before continuing his education and football career at the University of Montana. As a member of the Montana Grizzlies, he developed into a formidable defensive force, earning All-Big Sky Conference honors and showcasing the relentless motor that would catch the attention of NFL scouts. His college career culminated in his selection by the Atlanta Falcons in the fifth round of the 2008 NFL draft, a moment that marked the beginning of his professional journey in the league's highest tier.

Biermann's NFL career with the Falcons spanned from 2008 to 2016, during which he established himself as a versatile and durable linebacker. He played a key role in the team's defensive schemes, amassing over 200 career tackles and 17.5 sacks, including a standout 2012 season where he recorded a career-high five sacks and helped lead Atlanta to the NFC Championship game. His contributions were particularly notable on special teams, where his speed and tackling ability made him a valuable asset. However, his time in Atlanta was also marked by injuries, including a torn Achilles tendon in 2013 and a knee injury in 2015, which ultimately led to his release from the team in 2016. He briefly signed with the Buffalo Bills in 2017 but was waived before the regular season, effectively ending his professional playing career.

Off the field, Biermann's life took a dramatic turn when he married Kim Zolciak in 2011, a relationship that thrust him into the spotlight of reality television. The couple, who met at a charity event, starred together in Don't Be Tardy, a spin-off of The Real Housewives of Atlanta, which chronicled their blended family life with six children. The show ran for eight seasons, making Biermann a familiar face to audiences and solidifying his status as a reality TV personality. Throughout this period, he also pursued ventures outside of football, including a brief stint as a contestant on the cooking competition series Rachael vs. Guy: Celebrity Cook-Off in 2014, where he showcased a more lighthearted side.

In recent years, Biermann's public narrative has been dominated by his highly publicized divorce from Zolciak, which was finalized in 2024 after a contentious legal battle. The couple's financial struggles and the dissolution of their marriage became tabloid fodder, but Biermann has remained focused on co-parenting their children and rebuilding his life away from the cameras. While his football career may have been cut short by injuries, his legacy endures both as a dedicated athlete who gave his all for the Falcons and as a reality TV figure whose personal journey has resonated with audiences. Today, he continues to navigate life as a father and former athlete, with his story serving as a testament to the unpredictable intersections of sports, fame, and family.
