Nan Grantham


Nan looks back over decades of music with all ages and her passion for sharing it with both children and adults has never decreased! Holding both undergraduate and graduate degrees in Music Education from Mississippi College in Clinton MS, she has used them in careers as private and public school teacher, home school music developer, piano teacher, and church musician in Mississippi, Louisiana, and Texas. A contributor to many Chorister Guild articles, she also authored the Language of Music series. After 30+ years of writing curriculum and children's songs for LifeWay, she continues to write for Growing in Grace.

After moving to Texas in 1996, she worked with Houston's Children Chorus for several years before (as her friends say) "failing retirement!" But those preschool roots keep calling her back and the cycle continues...the love of music never goes away...nor the desire to plant it in the lives of children. Now, in addition to writing and conferences, she volunteers at her church as musician and Bible study teacher.

She is the proud Mom to a son and daughter, Grandmom to 7 grandchildren, and soon to be Great-grandmom.
