Lauren developed a love for cross-cultural missions during a three-month YWAM Crossroads course in 1991 after her 1st husband passed on. Since that time, she and her husband, Dan have helped inspire others to fall in love with serving the poor in Jesus’ name. “I’ll go wherever He sends me because my life is simply not my own. What a joy it is to live for Jesus!”
Lauren and Dan enjoy life in Boise, Idaho, with their six children and seven “grandbeauties.” They love God, their church, the outdoors, riding bikes around town, and sharing life with friends.

The call that God put on my heart to choose Kenya was nothing more than a strong desire inside – so I went.”
