Better known to many as Damo, the stout Irishman is a full-time professional wrestler and wrestling coach based in Glasgow.
Damo has travelled the length and breadth of the UK to train under various experienced veterans of wrestling. Most recently O'Connor has spent a lot of time with current WWE NXT trainer and British Wrestling legend Robbie Brookside. Previous to that he has learned under Doug Williams, Prince Fergal Devitt, Johnny Moss and many others.
