Christian McCartney began entertaining family members and guests when he was in pre-school, which is also when he began studying greats such as Jim Carrey, Tommy Davidson and the Wayans brothers on In Living Color.  He began doing standup at age 19 in Baltimore, Maryland. His comedy is a combination of animated storytelling, energetic characters, and pure entertainment.

Christian portrayed Levi in the Amazon Prime series spin off of the Andy Griffith Show known as Mayberry Man.  In January of 2024 he made his TV debut  as a special guest performer on Huckabee on the Trinity Broadcasting Network. Two weeks after Huckabee, Christian headlined the FedEx Forum in Memphis Tennessee for the Memphis Grizzlies Faith and Family Night.
