In March 2015, Yves Guérin took over as club chair and appointed Christophe Bouhour professional team manager.
Since 2014, the club has given itself the means to access the French elite by recruiting many recognized players, such as Sophie Herbrecht, Ionela Stanca-Gâlcă first, then Linda Pradel, Koumba Cissé or Ana de Sousa in the summer of 2015.
Second in the 2015–2016 season in Division 2, Chambray accedes for the first time in its history to the elite of French women's handball.
After a difficult start, Chambray won the first match in its history in LFH on the eighth day at home against Brest Bretagne Handball.
From then on, the promoted followed a series of nine victories in fourteen meetings allowing them to finish in sixth place in the ranking with a record of nine wins, two draws and nine losses.
