He became the third igumen of the Iveron Monastery on Mount Athos and, according to some sources, was a nephew of the first abbot, St. John. After the resignation of the abbot St. Euphemius, he actively managed the monastery, under his guidance the main church of the Dormition of the Most Holy Theotokos was built. The wall inscription of the church states: "I have strengthened these columns, that they may not be shaken forever. Monk George the Georgian, Builder."
The abbot of Iveron was respected at the imperial court of Byzantium, but later he was slandered, accused of treason, and exiled to the island of Monovat, where he reposed in 1029. The exile of St. George proved to be fatal for the Iveron Lavra: the slanderers found a new reason to create an unbearably difficult situation for the Georgian brotherhood on Athos, during this time all the monastery's wealth was stolen and plundered.
Under the pious Emperor Michael VII, the Iveron Monastery was again returned its property, and love and warmth reigned in the monastery once more. The Georgian monks transferred the incorrupt relics from the island of Monovat to Athos.
