Frank Dufficy grew up in Stevenage and was educated at St Michael's School for Boys which amalgated with St Angela's to become the John Henry Newman School. Living not far from the Stevenage Swimming pool Frank was attracted to diving, spending hours spectating at the Beaumont Diving Academy. The coach Derek Beaumont was concerned that his apparent lack of immediate talent might lead to him injuring himself but such was his enthusiasm and persistence that he was eventually persuaded to allow Frank to join the squad. It was a good decision because success soon followed. Frank became British Champion at the 10 metre highboard in 1972 and 1973.
