19, 2020, Casey announced that McGreevy's would be closing down after 12 years due to the economic fallout of the COVID-19 pandemic. In 2009, Casey founded The Claddagh Fund, a charity foundation based on the attributes of the Irish Claddagh symbolism: "Friendship, Love and Loyalty." It was founded with the help of Boston Bruins legend Bobby Orr. In October 2014, Casey, a lifelong Democrat, announced that he was co-hosting a fundraiser for Republican gubernatorial candidate Charlie Baker. Casey stated that "Charlie is a Republican and I'm a Democrat, but I will take a big heart and strong character over political party any day." Casey, who publicly backed Mayor Marty Walsh's campaign in 2013, also said that Baker helped several of Dropkick Murphys' charitable causes over the years, including supporting military families. Casey is among many Massachusetts Democrats to have supported Baker. On May 20, 2016, Casey and the Dropkick Murphys received the "Robert F. Kennedy Children's Action Corps' Embracing the Legacy Award" for years of charity work with various organizations including work with children and military veteran. The award, "which parallels Robert F. Kennedy's quest for social justice on behalf of society's most vulnerable people" will be presented to the band at the Kennedy Library.

The band was unsure if Casey would be able to begin their 2018 summer tour due to the injury. However, Kevin Rheault, the band's longtime stage tech and who filled in for other band members in the past, has filled in on bass at the band's live shows. As of 2021, Casey has still not returned to playing bass during their shows. During a St. Patrick's Day show at the House of Blues on March 17, 2019, Casey attempted to defend fans that were being attacked by another concert-goer. He was hit in the head by a beer can, causing blood to appear on his face, though he stayed on stage and finished the concert while the involved fan was escorted from the building. In April 2021, Casey announced that he had returned to college at UMass to finish up his college
