He started his playing career when he was a teenager in the Panathinaikos F.C. Academies. After spending some years in Panathinaikos as an amateur he was finally given a chance to prove his worth as he was given on loan to FC Marko Markopoulo for 2 seasons (2001–2003). While playing for FC Marko he played a total of 38 league matches and scored 11 goals. In the 04/05 season he was given again on loan, this time in Proodeftiki FC and played 26 matches and scored 2 goals.
Unfortunately his promising career stopped dramatically in the first day of the 2007-08 season in a derby against Olympiakos when a torn ligament injury sidelined him for two full seasons. The knee was damaged (torn posterior cruciate ligament, lateral collateral ligament rupture, ruptured popliteal tendon, torn posterior bursa and torn medical and lateral meniscus of the left knee) and was described by experts as the most serious injury in the recent years. He returned in training around January 2009 but he failed to appear in any games. 
At his 1-year loan spell in Kavala FC in 09-10, he managed to earn his first cap against PAOK FC, playing for 9 minutes. He returned at the end of the 09/10 season on the Panathinaikos roster and was again loaned at Ilioupoli F.C. for the 2010–2011 season. For the next two seasons,he played for Football League clubs Apollon Smyrnis and Fostiras. In the 2012-13 season, playing for Apollon Smyrnis he managed to win the Football League championship.
