Kim Ballestero remembers playing the accordion and singing with her sister in children's church when she was seven years old. Soon after, her parents started a home missions church where she assumed the title of "church organist". In high school, Ballestero sang Christian songs even when it "wasn't cool". She always knew God had his hand on her life.

In 1990, Ballestero graduated from Jackson College of Ministries in Jackson, Mississippi with a Bachelor of Arts in Gospel Music. During her senior year, she traveled with the Lanny Wolfe Singers.

In 1991, Kim married Anthony Ballestero. Together, they began to work for the Lord in full-time ministry as youth pastors of the First Pentecostal church in Jackson, MS, where Kim led the youth choir. Even though they moved on to other areas of ministry, she was always involved in leading choirs or playing and singing in church.

Then on May 12, 1996, Kim and her husband pioneered a church in Clearwater, Florida, "The Pentecostals of Clearwater". Even though their first priority is building a church in Clearwater, Kim is still very involved in music ministry outside their local church, teaching choir clinics, leading music for conferences, and singing at various events .

A mother of three, Kim Ballestero is dedicated to carrying out the call that has been placed on her life.
