Debby Kerner & Ernie Rettino are American musicians best known as the creators of the characters from the Psalty the Singing Songbook in the Kids' Praise! series of Christian children's musical albums. Together, they have also created Solomon the Supersonic Salamander, and Hi-Tops (a musical for pre-teens and teens).
Kerner started off as a solo Christian singer in 1969. She and Rettino met at Calvary Chapel Costa Mesa in Southern California, where she led worship. They have been making music together since the mid-1970s. They were married in 1976 and named the album they released that year "More Than Friends".
In 1979, the duo created a cartoon character for children by the name of Psalty the Singing Songbook. Psalty was introduced in the "Kids Praise" Series, which was produced by Maranatha Music between 1980 and 1991.
In 2006, Kerner became Director of Worship Leadership at Saddleback Church; she trains and mentors worship leaders and oversees venues at the church's Lake Forest campus. She graduated from Golden Gate Baptist Theological Seminary with the Doctor of Ministry degree in 2010. She is now Dr. Debby Kerner Rettino.
