He is a right-sided defender who has made a number of appearances for Greece's youth teams. More of an endurance player than a virtuoso, he is distinguished by exceptional leg strength.
He played an important role and became a vital player for Larissa during his years with the club, including Larissa's appearances in the UEFA Cup group stages during the 2007–08 season, attracting interest from Greece's bigger teams. He is the son of Giannis Galitsios, who was also a star player for his hometown team, Larissa, in the 1980s.
Scored first league goal on 7 October 2007 in Larissa's 3-3 home draw with Levadiakos, followed it with another against Panathinaikos the following month. He ever-present in club's six-game UEFA Cup run, which included elimination of Blackburn Rovers FC. He made a positive impact in his first Super League campaign, 2005/06, appearing in 27 of the team's 30 matches, helping them finish eighth a season after promotion.
Olympiakos agreed with Larissa for the acquisition of 22 years' old defender, who will stay in the club till the end of the season. The transfer is closed to a fee of €800,000 plus a 20% resale. Galitsios agreed to sign a five years' contract, while earnings will be graded starting from €300,000 annually.
A wholehearted right-back with tremendous stamina, Giorgios Galitsios joined Olympiacos in January 2008 after displaying consistent form over several seasons for provincial Greek club Larissa FC and joined for the 2008–09 season. He played against a vital Champions League qualifier against Arsenal F.C, but in the 75th minute he suffered a minor injury, which led to him being substituted. George Galitsios some years later stated that : "My character put me into trouble sometimes. Moreover, my eccentricity plays a key role in Olympiakos. It was a totally bad behavior".
After three years, he succeeded to have only 45 appearances in all competitions with the club.
On 28 January he joined Panionios F.C. on a 6-month loan. The player had also an offer from his former club Larissa, but he preferred to join Panionios having the opportunity to play a key role replacing Giannis Maniatis.
During the winter of 2011-2012 he signed a contract at Koninklijke Sporting Club Lokeren in Belgium after being released from Olympiacos in July 2011.
The former defender of Olympiakos is signed a six-month contract as Lokeren looking to cover the right side of its defense, concluding that Galitsios could be an ideal case. He was in search for a team after his training period with Werder Bremen.  He made his debut with the club in an 1-1 away draw against OH Leuven. On 26 December 2013, he scored his first goal with the club in a 3-0 away win against KV Oostende.
Galitsios signed for two more years with the club till the end of 2014/15 season, as the management of the club was completely satisfied with his performance and activated the option that existed in their agreement. The defender was surprised when he hears the news. "But it makes me happy of course. I feel good at Lokeren, Lokeren is satisfied with me. Club could unilaterally extend my contract. So that's happened now," said Galitsios. Lokeren coach Peter Maes gives some explanation. "'Gali' is a player that you can always count on. Moreover, he has made tremendous progress in the last year and a half. Initially he was a Greek, he is now more 'European'. I mean football for him was more of a game, and now is more of a job. In terms of efficiency, professionalism and discipline in the game has grown tremendously, in line with club expectations." 
On 22 March 2014, Lokeren fired a second Belgian Cup in three seasons in his pocket. Lokeren won with the smallest difference from Zulte Waregem. "This is an important victory in the history of the club," said Giorgos Galitsios afterwards. "Lokeren already picks up a second trophy in three seasons. Lokeren is simply a top club." "It was a hard fought victory", the defender continued. "But that's normal for a finale, huh. Though we eventually did have the better of the game. So I can say that we are a deserved winner." 
Georgios Galitsios is another season under contract with Sporting Lokeren. However, the Greek right back enjoying interest from Panathinaikos, but Lokeren, however, would require a half million euros for the 27-year-old defender.
Lokeren technical director Willy Reynders revealed that Giorgos Galitsios has taken the decision to return to Greece at the end of the 2014/15 season confirming SDNA reports.“I think that Galitsios has taken his decision. He is a father and he wants to return back to Greece. But this decisions come along with its effects. Nonetheless, we've got Melnjak as an alternative solution,” Reynders said.  Galitsios has 137 appearances (1 goal, 14 assists) with the club in four years.
After a period of six months as a free agent, Galitsios is ready to return to his former team Lokeren. The 29-year-old player six months after he terminated his contract with the Belgian club, which came close to return in Greece for PAOK this January, besides the interest of 1. FC Köln, 1. FC Nurnberg and APOEL spent four years with the club. He will sign a 1,5 years contract on a fee of €500.000 with bonuses. On 13 February 2016, he made his debut with the club in a 3-3 away draw against Oud-Heverlee Leuven,as a substitute. On 7 May 2016, he scored his second goal in Belgian Pro League in a home win against KV Mechelen. He started the 2016-17 season as the undisputable leader of the right side.
After getting more actions for Olympiacos in the 2009–10 season, Galitsios was called up on 15 November 2009 by Greece national football team coach Otto Rehhagel for the second leg of the 2010 FIFA World Cup qualification play-offs against Ukraine.
