Psimogiannos started his football career at the club of his village, Aris Agios Konstantinos, where his brother Antonis played as well. With Psimogiannos as a key and irreplaceable member of the offensive line, the team of Aris Agios Konstantinos achieved their promotion to the second division in 1970 after three play-off matches against Paniliakos. The achievement was surprising by the standards of the time, as it was unprecedented for the team of a large village of 2,000 inhabitants to compete in a national division. Psimogiannos played with Aris Agios Konstantinos in the second division and at the end of the season the team was relegated in 1971, unable to withstand the intense competition of the division, and Psimogiannos having attracted the interest of the big clubs with his performances, he was transferred to AEK Athens, the team he supported as a child.
During his spell at the club the fans of AEK from Agios Konstantinos organized trips to Nea Filadelfeia to see their fellow countryman playing. The transfer of Psimogiannos to the club became the cause of the establishment of AEK Agios Konstantinos, a club founded by refugees of AEK at the area in the early 80's.[2] A dynamic centrer-forward with great physicality, Psimogiannos found a place in the club's squad, being in many matches the strong and solid player of the offense, that broke the opposing defenses. He managed to play with AEK in the UEFA competitions making 4 appearances. as he played the full 90 minutes in the 3–2 home win over Internazionale on 29 September 1972 for the European Cup[3] and as a substitute in both legs against Salgótarján in September 1972[4][5] and in the 1–3 home defeat by Liverpool on 7 November 1972 for the UEFA Cup.[6]
In the summer of 1974, the president of the club, Loukas Barlos negotiating the acquisition of Georgios Dedes, alongside Giorgos Skrekis and Victoras Theofilopoulos from Panionios was asked for Psimogiannos among the exchanges.[7] Psimogiannos accepted the move and on 8 August the transfer move was completed, with him moving to Panionios alongside Kostas Panagiotopoulos and Ivan Kypritidis.[8] In fact he left everyone surprised when in a television interview with journalist Kostas Kyriazis, as the new transfer acquisition of Panionios, stated that he accepted only because it was dictated by the interest of AEK.[9] He played for Panionios for two seasons, before the arrival of Nikos Anastopoulos from Dafni in the summer of 1976, which led Psimogiannos to move to Apollon Athens, where he played for three seasons. In the summer of 1979, he returned to Aris Agios Konstantinou, where he played until the end of his football career in 1984.[10][11]
