Before moving to Texas she served in Louisiana as supervisor of music for the Shreveport and Caddo Parish schools.

In the Music Educators National Conference she served as a member of the Education Research Council and as chairman of the National Committee on Music for the Elementary Teacher. She contributed articles to the Music Educators Journal, The School Musician, Southwestern Musician, and other publications. She wrote Songs to Play (1954) and The Keyboard Way to Music (1956) and was a coauthor of the widely used elementary textbook series This Is Music for Today (1971).
