Sylvia Holtzhausen

Genesis Design Author, Teacher, Trainer and Lesson Writer

Sylvia Holtzhausen is the author of the Genesis Design Curriculum which she developed over many years of getting to know the lives and struggles of children, youth and adults. Sylvia has a Bachelor’s Degree in Biblical Studies and years of teaching experience. She and her husband Jos, served God through Youth for Christ, first in South Africa and then in Namibia. In 2003, they started Christ’s Hope International which focused on ministry to AIDS affected orphans and vulnerable children. In 2019, they moved on to make Genesis Design a stand-alone ministry.

“I love teaching and am passionate about what I teach. I love to see lives being transformed as young people all over Africa are becoming CycleBreakers. But no amount of teaching or good programmes can bring about change. As Paul said, “All that matters now is one created anew.”  And that only comes about when a person is redeemed through Jesus Christ.”

Alicia Metz


Alicia is married to Robert and they have two daughters. She is a English and Mathematics secondary school teacher. She has always enjoyed teaching the gospel of the Lord Jesus Christ to young children and teens. “What we need are courageous men and women who love and study Scripture and stand up for the sometimes-challenging truths in God’s Word. Knowing what it costs to find out about a godly way of growing into adults and starting a family late in life, I really value the work of Genesis Design. By teaching them Scripture, people have the chance to recognise the falsehoods in popular thought and instead, experience the Lord’s blessings in marriage and family.”
