The church started as one campus in Amarillo in 1956. After being landlocked and still growing, in 2006, the church relocated in Amarillo under the leadership of Tommy Politz (now Pastor Emeritus) and changed names to Hillside Christian Church. Hillside continued to experience rapid growth in that season, and made the decision to add campuses in different locations. Hillside now consists of 10 physical campuses in the Texas Panhandle and Eastern New Mexico.

The church is led by Senior Pastor Johnathan Mast, who stepped into the role a year and a half ago, after serving on staff for 23 years. The church continues to grow,  experience hundreds of baptisms every year, and is committed to helping people experience the Love of Christ.
