  • Christi Aeschleman

    assistant children's Director

    Christi Aeschleman is the new Assistant Children’s Director.  Christi and her family have been attending Frontline for about one year now.  They were drawn to Frontline right away; jumping in and volunteering at VBS, Trunk or Treat, and the Happy Birthday Jesus party.  With six kids, ranging from 3 -19 years old, they cover just about every age group on Sunday mornings too. Here’s an interesting fact about the Aeschleman family; five of their six kids are adopted!  Two separate sibling groups, through foster care.  (But bet you can’t figure out which is which.)  It reminds them that when we accept Christ into our hearts, we are adopted into God’s family.  Unique individuals, with different stories and backgrounds.  But made perfect, inseparable, and loved!  How awesome is that!  She looks forward to having an exciting year of planting seeds in the hearts of God’s children.
