Lisa, who has been exposed to music since she was a child, once received orthodox vocal training at the leinster Conservatory of Music in Dublin. She was discovered by her tutor a long time ago, but she actually has a strong interest in musicals. She also participated in many performances, such as Florence Vasi in the chess drama. Or the role of Wilma Kelly in Chicago, Magic of cole potter, Music of irving berlin and so on. Can appreciate the charm of this showgirl. It was not until 2000 that she devoted herself to the performance of riverdance and toured the United States and Canada.

In 2002, Lisa was invited to record her solo album "Lisa", including the songs "Raise your Wings from riverdance" and "The Deer Cry".

In 2004, Lisa attended the Celtic women's concert, which was supposed to be just a performance. However, because the concert was well received in the United States, Celtic women began to tour as a group, and Lisa was one of them.

In 20 12, Lisa announced that she had temporarily left the Celtic woman because of pregnancy, and Susan mcfadden (Brian McFadden's sister) took over her position temporarily.

In 20 13, Lisa announced that she would leave the Celtic women with her husband Scott Porter (CEO of Celtic women) and set up the lisa kelly Institute of Sound, a performance training school.
