2012–2015: The A1 experience

The club competed in the first tier professional basketball league in Greece (Greek Basket League) for first time in its history in the 2012–13 season. Panelefsiniakos made a mediocre start at its debut Greek Basket League season, as the team registered just 2 victories in the first 10 match days of the league. The team spent the first round playing at Peristeri Arena (17 km away from the town of Elefsina), due to necessary renovation to its home court which lasted for about 3 months. In order to avoid relegation, Panelefsiniakos improved its performance in the following months and got crucial wins at home against PAOK, Panionios and Peristeri. The team of coach Giorgos Skarafigkas beat also KAOD and Rethymno and finished the season with a 7–19 record (11th spot in the standings). Greek combo guard Nikos Liakopoulos was team's season MVP with 15.3 points per game on average and generally had great contribution.

After the end of a successful season, Panelefsiniakos made a lot of important changes to its roster in summer of 2013, including the addition of Olympiacos former captain and Greek NT member Manolis Papamakarios. The blue-whites begun strongly the 2013–14 season with 3 victories in the first 5 games, one of them on the road against Ikaros at Chalkida. Two match days before regular season's end, Panelefsiniakos, led by swingman David Kyles who scored 20 points and grabbed 4 rebounds, crushed Trikala at home and made a decisive step in order to stay at the top division. Finally, the goal was achieved as the club, despite its ups and downs during the year, once again managed to avoid relegation. Coach Skarafigkas' players celebrated 7 wins, in a season where center Larry Turner (9.2 points and 3.2 rebounds per game) and power forward Mouhammad Faye (13.5 points and 7.6 rebounds per game) were solid.
