Born in Havana, Cuba, Lourdes C. Montgomery moved to the United States at age five. She studied jazz piano at Miami-Dade Community College with Sanford Gold and, at the University of Miami, music composition with Dr. Dennis Kam as well as classical piano with Dr. Rosalina Sackstein. Many of Lourdes' sacred and liturgical compositions are published by Oregon Catholic Press, who also produced her CD entitled "De La Cruz a la Gloria", and World Library Publications.

In 2008, Lourdes was honored to have her song Bienaventurados ("The Beatitudes") was performed at the mass of Pope Benedict XVI that was held at the National Stadium in Washington, D.C., and televised nationally. In 2005 Lourdes became music director at St. Vincent de Paul Church in the Ozark Mountains of NW Arkansas, where she now lives with her double bassist husband Michael Montgomery.
