Born in Athens, Tziortziopoulos started his career at third division side Keratsini in 1997 and his performances caught the eye of Olympiacos, who signed him in the summer of 1998.
Six months later he went on loan to Iraklis, where he played until January 2000, when he returned to Olympiacos to make his debut.
The defender, a former Greek U21 international, played ten times as they won the league, but only made four more appearances in the following two triumphs.
On 7 June 2007, Tziortziopoulos was released by AEK Athens and immediately signed with the Cypriot side Omonia.
