At the time of the choir’s formation in 1993 Pueri Cantores San Gabriel Valley’s sole purpose was to bring singing children together, from across the San Gabriel Valley region of Los Angeles County, to participate in the Twenty Sixth International Congress of Pueri Cantores (Young Singers) in Rome. Under the direction of Patrick Flahive the choir joined with nearly 10,000 choristers from around the world for ceremonies, rehearsals and concerts in the eternal city. The grand conclusion of that Congress was the celebration of the Mass of January 1, 1994 with His Holiness, Pope John Paul II in St. Peter’s Basilica.

The success of that musical journey led Patrick and his wife, Lauren, to establish the choir as a permanent ensemble committed to educating young singers in the art of sacred choral music. With an annual concert series and numerous demands for the choir to sing in Southland area performances and ceremonies, Pueri Cantores San Gabriel Valley has enjoyed many years of exciting musical adventures, and children from across the region are currently involved in the Cherubim (preparatory), Seraphim (intermediate), Queen of Angels (advanced trebles), and Pueri Archangeli (young men) ensembles.

PCSGV was the only children’s choir to sing for the 2002 ceremonies surrounding the dedication of the Cathedral of Our Lady of the Angels in Los Angeles and has continued to sing there on many occasions in liturgies, concerts and operatic performances. The singers of PCSGV have participated in numerous ceremonies, concerts, recordings, television and films.
