The ACS is made up mostly of Ateneo College Glee Club alumni who now lead various lives as professionals: people in the medical field, the corporate world, the academe, media practitioners, free-lancers as well as homemakers – all of whom share a passion for choral singing and have chosen to contribute their talent to this group.  Some of its members have reaped awards and recognition in the Philippines and abroad: resident composer Robin Estrada has earned his Ph.D in music at the University of California in Berkeley; composer and arranger Gianpaolo Eleria graduated summa cum laude from Berklee School of Music in Boston; media personality Angelique Lazo and award-winning composers Trina Belamide, Arnel De Pano and Von de Guzman are also some of the group’s famous personalities. 

Outside of ACS rehearsals and performances, these choristers hang out together and enjoy each other’s company when schedules allow them to.  Even members who have left the group to live in other countries remain part of this growing family, as ACS members are bonded for life by love and music.
