Tom O'Neill

Coach

Tom started CrossFit in 2024 after deciding it was time for a change from years of more traditional powerlifting and bodybuilding-style training. He was quickly hooked by the variety of CrossFit and the fact that there is always another skill to learn or something to improve.

He joined the CFC coaching team in March 2026 and particularly enjoys helping members develop their skills and confidence. His favourite coaching moments are when members realise that they’re more capable than they thought.

Tom is a CrossFit Level 1 Trainer and is currently completing his British Weight Lifting Level 2 qualification. He also enjoys competing in CrossFit and judging at competitions, experiencing the sport from both sides of the floor.

Outside the gym, Tom works as a dentist. When he isn’t working, training or coaching, he enjoys travelling and can usually be found planning his next trip.
