From 2009 to 2016, Cabell worked as the COO and CEO of Abbey Road Control, a flagging and traffic controlcompany. From 2016 to 2021, he operated the Silver Pines Treatment Center in Schuylkill County, Pennsylvania. He later co-founded and served on the board of Civiq Health. Cabell was elected to the Pennsylvania House of Representatives in November 2022. Cabell was defeated in 2024 by primary challenger Jamie Walsh. The vote margin between the two ranged between three and five votes in Walsh's favor as the countyelection board tallied or rejected mail-in votes. Although the results remained unofficial, Walsh held his lead into July after the board tallied un-opened provisional ballots. Both Cabell and Walsh launched court challenges to swing the results in their favor, but it was Walsh who ultimately held a four-vote lead after all challenges were settled. Cabell conceded the race on September 23, the day the election results were certified.
