During his rugby playing career, Paul played with UCC, Munster, Blackrock, Saracens, Leinster, Ireland and the British and Irish Lions. Before retiring due to serious injury in 2003, Paul won 46 caps for Ireland (including 95 and 99 RWCs) and also played the full duration of all 3 tests in South Africa with the victorious 1997 British and Irish Lions. The 1997 Tour is seen as the definitive tour of the professional rugby era - the series was a unique victory against the odds, which was captured so well in the stand out 'Living with the Lions' documentary. Paul was a very influential player in the winning of this series and was described by the captain, Martin Johnson, as 'my player of the series'. In addition, Paul is a member of an exceptional Irish sporting family - all 3 Wallace brothers have made the Guinness Book of Records as the only 3 members of one family to play for the Lions - a unique achievement in international sport'. Together, the Wallace brothers have 147 Ireland caps.

In addition to his media and speaking commitments, Paul is Managing Director of Bircroft Property Finance (Ireland), an International debt structuring firm for commercial property. He formerly worked for International property company, Jones Lang La Salle, dealing in international property sales and acquisitions.

Paul is also Patron of CROSS Cancer Research and founder of the CROSS Cycle which has raised over €500k to date.

Paul is an excellent speaker, articulate, modest about his achievements, but full of good humour and stories. His strength of character and integrity as a player has followed through into this next phase of his career.
