Early years and rise of the club The club began play in the 1971–72 season. In the 1977–78 season, Peristeri won the
third level championship of Greek pro basketball, under head coach
Faidon Matthaiou. In the 1982–83 season, under head coach Thanasis Christoforou, Peristeri won the second level championship of Greek pro basketball, which was at that time, the
Greek B League. In the following 1983–84 season, Peristeri played games for the first time, in the top-tier level
Greek Basket League. Peristeri won the
Greek 2nd Division championship again, in the 1988–89 season. In the subsequent years, the team was very successful, and many well-known basketball players played for the club. During this era, Peristeri competed in the
European 3rd-tier level
FIBA Korać Cup seven times (in the seasons
1991–92,
1992–93,
1993–94,
1994–95,
1996–97,
1997–98, and
1999–00). Well-known players such as:
Audie Norris,
Marko Jarić,
Milan Gurović,
Angelos Koronios,
Michalis Pelekanos,
Kostas Tsartsaris,
Alphonso Ford,
Benoit Benjamin,
Gary Leonard,
Randy White,
Marlon Maxey, and
Conner Henry played for the club in that era. In the
2000–01 season, led by the great scorer
Ford, Peristeri finished in second place in the top-tier
Greek League, in the regular season. The club also competed in the
European-wide top-tier level
EuroLeague competition, during the
2000–01 and
2001–02 seasons. In the
2002–03 season, Peristeri competed in the European third-tier level
FIBA Europe Champions Cup. In the
2003–04 season, the club played in the European 3rd-tier level
FIBA Europe League.
Decline of the club Following the
2003–04 Greek Basket League season, Peristeri was
downgraded to the second division
Greek A2 League for the 2004–05 season, due to great financial troubles within the
Peristeri Sports Club. The club also competed in the Greek 2nd Division in the 2005–06 season. The club was then
relegated down to the
Greek 3rd Division, for the 2006–07 season. After winning the Greek 3rd Division championship, in the 2006–07 season, Peristeri returned to the Greek 2nd Division, for the 2007–08 season. Peristeri then won the Greek 2nd Division championship, in the 2008–09 season. Peristeri then competed in the top-tier level
Greek 1st Division, in the
2009–10,
2010–11,
2011–12, and
2012–13 seasons. After the 2012–13 Greek Basket League season, Peristeri was again relegated down to the second-tier level Greek A2 League. However, due to economic issues, the club did not take part in the A2 League in the following season, and instead competed in the third-tier level Greek B League, during the 2013–14 season. Peristeri managed to win the 2014–15 edition of the Greek 2nd-tier level ESKA Cup competition. While in that same 2014–15 season, Peristeri finished in fourth place, in the First Group of the third-tier level Greek B League, and thus did not earn a direct league
promotion. Nevertheless, due to the withdrawal of
Panionios Athens from the second-tier level Greek A2 League, Peristeri was then promoted back up to the A2 League, as they replaced Panionios in the competition, for the
2015–16 season. However, following that season, the club was relegated back down to the Greek 3rd Division, for the 2016–17 season.
Return to European-wide competitions Peristeri won the
Greek 3rd Division in the 2016–17 season. Then, in the following
2017–18 season, Peristeri won its third
Greek 2nd Division championship. The team broke the league's win–loss record during that season, and finished with an overall record of 29 wins and just 1 loss. Thus, the club was
promoted up to the
top-tier level
Greek Basket League, for the
2018–19 season. The return arrival of head coach
Argyris Pedoulakis proved to be a key factor for the team. With Pedoulakis coaching, and with a core of quality players, Peristeri finished second in the regular season, and in fourth place overall at the end of the league's playoffs, which thus secured the team's return to European-wide competitions. The club then joined one of the two European-wide secondary leagues, the
FIBA Basketball Champions League (BCL), for the
2019–20 season. The team had a successful BCL season, as they managed to progress to the round of 16 of the FIBA Champions League, where they were ultimately eliminated by the
Israeli Super League club
Hapoel Jerusalem. Peristeri finished in the third position of the
2019–20 Greek Basket League season, although the Greek League season ended prematurely, in March 2020, due to the
COVID-19 pandemic in Greece. Peristeri were the finalists of the
2020 edition of the
Greek Super Cup competition, after they defeated the Greek
EuroLeague giants
Panathinaikos Athens, by a score of 90–82 in the semifinals. They lost to
Promitheas Patras, by a score of 82–74 in the finals. Peristeri's
2020–21 Greek Basket League season wasn't as successful as the previous one, as they finished in sixth place in the league. In European-wide play, they also competed in the
2020–21 FIBA Champions League season. During that season, the team used three different
head coaches. The team also struggled to develop proper player chemistry throughout the duration of the season. Ultimately, Peristeri was unable to match their high points of the previous two seasons. Under head coach
Milan Tomić, Peristeri finished the
2021–22 Greek Basket League season in 8th place. While in Pan-European competition, they competed in the European-wide fourth-tier level
FIBA Europe Cup competition's
2021–22 season. In August 2022, the team was given the new sponsorship name of Peristeri B.C. Athens Bwin, after the club secured a naming rights deal with
Bwin, for the purposes of increasing the team's budget, as part of an overall effort by the club to position itself in a higher echelon within the Greek Basket League.
An international legend becomes the head coach Peristeri hired international basketball legend
Vassilis Spanoulis to its head coaching position, for the 2022–23 season. Spanoulis guided the team to its first ever appearance in the Final of the
Greek Cup competition. However, they were defeated in the
2022–23 Greek Cup final by the
EuroLeague giants
Olympiacos Piraeus. In the
2022–23 Greek Basket League season, Peristeri finished in third place in the league, after they beat the Greek Fiba Champions League club
PAOK Thessaloniki, in the league's third-place series. During the season, Peristeri managed to beat the EuroLeague giants
Panathinaikos Athens, three different times during the overall season. In European-wide play, Peristeri also competed in the
2022–23 FIBA Champions League season, where they were eliminated in the play-ins by the
French Pro A League club
JDA Dijon, 2–1 in a three game
series. In the
2023–24 FIBA Champions League season, Peristeri had an astonishing year and for the first time in team's history,the team reached the
2024 FIBA Champions League Final Four. In the semifinals, Peristeri was knocked out of the Final Four tournament, after a 97–94 defeat to the
Spanish ACB League club
Tenerife. Ultimately, Peristeri finished in fourth place in the FIBA Champions League season, after they lost the bronze medal game against the Spanish ACB League club
UCAM Murcia, by a score of 87–84. Spanoulis was ultimately named the
FIBA Champions League's
Best Coach of the Season. In Greek national domestic competitions, Peristeri made it to the semifinals of the
2023 Greek Super Cup competition, where they lost to
Olympiacos Piraeus. They took the 3rd place by beating PAOK. Peristeri also made it to the quarterfinals of the
2023–24 Greek Cup competition, where they again lost to Olympiacos. In the
2023–24 Greek Basket League season, Peristeri once again finished in third place in the league, after they beat the Greek
EuroCup club
Aris Thessaloniki, in the league's single third-place match. In 2025,
Betsson was announced as the team's naming partner and major sponsor leading the team to be officially renamed as Peristeri Betsson BC. ==Logos==
