Emily grew up in Minnesota, but has called Marshfield home for the past ten years. Along with her husband, Nick, she enjoys raising and discipling her four young children to know the Lord. Emily has served in children's ministry for many years, most recently at The Mill church in Stratford, WI, both as a volunteer teacher and a ministry leader. She has always felt called to work with children and enjoys helping them grow in their understanding of who God is. She is excited to get to know the children and families of Cornerstone. She and Nick have been humbled by the hospitality of the Cornerstone Church family and encouraged to see what God has already been accomplishing through Cornerstone Kid's Ministry. She desires to see Cornerstone Kids continue to be a place where children know that they are loved, cared for, accepted, and known, by their church family, friends, and most importantly a mighty and loving God.
