Keisel excelled at both football and basketball and initially wanted to go to college for basketball. He researched the statistics of players that were in the NBA at the time and found that his size wouldn't compare to those playing basketball at the professional level. He then turned his attention and athletic ability to football.
He is the son of Connie and Lane Keisel. He has three sisters: Peggy, Kalli, and Codi; and four brothers: Tom, Lance, Chris, and Chad. He is married to his high school sweetheart, Sarah. The couple have three children.
Since retirement from football, Brett and his wife Sarah have been involved with numerous charitable organizations, including the Cystic Fibrosis Foundation.[15]
In 2018, Keisel was a pallbearer at the funeral of brothers Cecil and David Rosenthal, who were killed in the Pittsburgh synagogue shooting. Their sister, Michele Rosenthal, was the former head of public relations for the Pittsburgh Steelers.[16]
"Da Beard"
Keisel began growing "Da Beard" while on a summertime hunting trip with his father.[17] Keisel's facial hair gained fame during the end of the 2010 NFL season.[18] Many NFL players grow "rally beards" during the playoffs to bring them good luck. His beard has its own Facebook page and Twitter account and was mentioned repeatedly in the media during the Steelers' playoff run.
In an interview on Steelers.com, Keisel explained that he had decided to grow out his beard after having a discussion about the lack of characters in the NFL. In another interview, though, to the Pittsburgh Post-Gazette, he said he wanted to change the team's luck, because it missed the playoffs the previous season.[19] On July 27, 2022, as a guest on Steelers' Defensive Linemen Cam Hewyard's "Not Just Football" Podcast, Keisel said that he started growing it partly due to superstition. He followed up saying that the Pittsburgh Penguins had just recently won the Stanley Cup, and that he saw the playoff beards the players grew, and was a fan of them, and wanted to try it out.
Keisel refers to his beard as a "beautiful thing" and "the greatest beard of all time"[19] and has, encouraged other Steelers to grow beards as well. After the Super Bowl several videos were made about Keisel's beard, including one that portrayed him as a HasidicJew.[20]
On February 24, 2011, "Da Beard" was removed during a ceremony titled "Shear the Beard" in downtown Pittsburgh. The event raised over $40,000 for the Children's Hospital of Pittsburgh of UPMC. Keisel stated that "Da Beard" would most likely return for the upcoming season. "Da Beard will decide when the time is right to come back," he said, "and it will all of a sudden appear." Keisel dubbed the 2011 season "Da Beard Revenge Tour". On February 9, 2012, Keisel held "The Second Annual Shear the Beard Event." Just as in the previous year, proceeds raised went to the Children's Hospital of Pittsburgh. It was announced on January 8, 2013, that "The Third Annual Shear the Beard Event" would be held on February 7, 2013, at Jergel's Rhythm Grille in Warrendale, PA, with all proceeds benefiting the cancer program at Children's Hospital. It was announced on January 14, 2014, that "The Fourth Annual Shear the Beard Event" would be held on February 5, 2014, at Jergel's Rhythm Grille in Warrendale, PA, with all proceeds benefiting the cancer program at Children's Hospital. Shear Da Beard recently celebrated its tenth and final year. Shavers such as Ben Roethlisberger, James Harrison, Cameron Heyward, and Arthur Moats have taken part in the shaving of Keisel's beard. Cancer survivor Sean Nolan has even joined in on the festivities.
