Dún Laoghaire Choral Society was founded in January 1982 by Séamus Crimmins, who had come to Dublin from his native Newry to take up an appointment in RTE.
Looking at the choral scene around Dublin he decided that the Dún Laoghaire area was a potential base for a new choir. After placing an advertisement in a local paper, about twenty people turned up to an initial meeting and the society was formed. Four months after it gave its first concert. Dún Laoghaire Choral Society rapidly established itself as a major musical force, giving concerts not only in the Dun Laoghaire area but in all Dublin's principal concert venues.
In 1990, Séamus Crimmins was succeeded as Music Director by Mark Armstrong. Under his guidance the choir expanded and flourished. One of the many memorable features of Mark's term of office was the revival of the annual "Messiah for All" concerts in Monkstown at Christmas.
Fergus O'Carroll took over as Music Director in January 2000. The highlights of his term of office included a most successsful celebration of the choir's twentieth anniversary with a performance of Haydn's The Seasons, and a thrilling account of the Brahms Requiem.
He was succeeded in the summer of 2004 by Cathal Garvey whose enthusiasm for English music brought about memorable performances of major works by Vaughan Williams and Tippett as well as a fitting commemoration of the Handel anniversary in 2009 with the dramatic oratorio Samson.
Following Cathal's decision to move to London in 2009 David Brophy was appointed Music Director.
