Originally from Cabinteely, Dublin, and later relocating to Foxrock, the 32-year-old gained recognition in the comedy scene.
However, his career didn't begin in comedy; his initial passion was music. At 23, he spent time in Los Angeles collaborating with Westlife singer Mark Feehily on music projects. Impressively, he earned a writing credit on an album alongside Joni Mitchell, renowned for classics like "Both Sides Now," as reported by The Sunday Times. Mark then moved to London in 2015 to work as a writer for the BBC but returned to Ireland in 2021.
