Although he had not yet made a mark on the international stage, ‘Irish Dongo’ had already built a strong reputation on the regional circuit. He dominated the amateur ranks, winning his career’s first title in 2012 and later capturing the Ulster Elite Heavyweight Championship in 2019. That same year, Paul represented his homeland against New York.
Coming from a boxing family in Belfast, Northern Ireland, McCullagh Jr carried forward a legacy that ran deep. While boxing might be a career or a passion for many, for him it represented a family tradition, following in the footsteps of his father, Paul McCullagh Sr, and his grandfather, also named Paul McCullagh. Growing up at his family’s gym, McCullagh’s ABC, Paul McCullagh Jr turned professional in 2020. He finished his career with a 2-0 record, with his last fight in 2021.
