Nancy started writing songs when she was 13 and released her first single "In Your Arms Again."
Nancy later teamed up with lyricist Jared Dunn and together they wrote numerous songs as the duo O'Connor & Dunn. Their song, "Which Way to Neverland?" was one of 15 songs selected for Curtain Up: Berklee's Annual Musical-Theater Songwriting Contest. It will be orchestrated and performed at the Berklee Performance Center. "Which Way to Neverland?" was also nominated for a SAMMY award (Syracuse Area Music Award) in 2019.
Nancy currently writes both solo and with various lyricists.
