[7] On 31 May 2007, the Royal College of Surgeons in Ireland in Dublin conferred him with the medical degrees of MB BCh BAO (NUI) LRCP&SI.

While playing at Leinster, his nominal 'local club' of origin was Carlow RFC, a provincial side which later got into financial difficulties and is now a minor Junior concern.

Contepomi was one of the stars of world rugby and was also set to lead the Argentina national team into a new era after being named captain in 2008.

The multi-talented Contepomi made his international breakthrough at fly-half and while he has played much of his rugby in that position he recently has found his place at inside centre with Juan Martin Hernandez preferred at No.10.

He also faced the British & Irish Lions in 2005 and at the end of 2006, he was part of the Pumas side that scored their first-ever victory over England at Twickenham.

Contepomi was a key player throughout the campaign – featuring in all seven matches as the Pumas claimed third place in the sport's global showpiece.

Following the retirement of veteran scrum-half Agustín Pichot, Contepomi was handed the captaincy of the Pumas in 2008 by new coach Santiago Phelan ahead of the opening clash of the year against Scotland.

Contepomi played his last international game with Argentina on Saturday 5 October 2013 in Rosario, Santa Fe, against Australia during The Rugby Championship.

In 2017, he gained his first head coaching appointment, taking on the role for Argentina XV ahead of the 2017 Americas Rugby Championship.

After the World Cup, Michael Cheika chose not to remain on with Argentina, and the union promoted Contempomi up to head coach of the national team in December 2023.
