Born in Trikala, Greece, Gregory Kotrotsios started playing basketball at the age of 8 and at age 17 signed his first professional contract with Ilysiakos B.C. During his 1st year he made an enormous impression that led to his invitation to the U20 Greece national basketball team making 2 caps in games against the U20 Russia national basketball team. During that year Kotrotsios was not only playing for the first team of Ilysiakos but also for its youth team that finished second in the Greek Youth Basketball League.
After spending some years on loan to gain playing experience, Kotrotsios was transferred to the prestigious A.G.O. Rethymno Aegean BC. He had a very successful year during which he was either the team's Starter or Sixth Man. He was a major contributor to A.G.O.R's promotion to the next higher league with only two defeats.
Following that successful year, Gregory followed up with numerous transfers to smaller league teams where he was a key player. In 2009, he signed with the highly reputed AO Pagrati BC, a legendary team for Greek basketball aficionados, currently playing in the second division of the highest professional basketball competition among pro clubs in Greece HEBA A2.
