In November 2002, Kirsten and her husband Bradley moved to the USA from South Africa. Soon after they moved, they began to search for a Natural Family Planning (NFP) method to use. They chose to use the Creighton Model System, which appealed to them because of the doctors who are trained in the system that can help specifically with fertility issues. Kirsten and Bradley found great success in this method, not only because of its positive impact on their fertility but also on their relationship. A biology teacher by profession, Kirsten was struck by the urge to share the Creighton Model with other people. After the birth of her first child in 2005, Kirsten qualified as a Fertility Care Practitioner in Creighton Model. This model has enhanced the strong relationship that she has with her body and her husband. She has been married for 20 years and has three beautiful children (Rachel, Samuel and Katherine).
