Hettie is married to the Gospel singer and music producer, Louis Brittz, and they have 2 daughters and a son.

As a former speech, language and hearing therapist, Hettie worked in a multi-disciplinary practice alongside a paediatrician, psychologist, occupational therapist and other speech therapists. She gained extensive experience in therapy and parental guidance. She also pioneered an educational upliftment project in Proclamation Hill where she worked with many challenging children (and their extremely challenging parents!), dealing with everything from nutrition and computer skills to molestation and spiritual counselling. It was while working at this centre that her passion for children and parents started her on a new career path. Since 2002 she has presented seminars across the country as well as overseas in churches, schools and corporate surroundings on a variety of topics related to Christian parenting and education. Her books “Kweek Kinders met Karakter” and “Kweek Gesonde Gesag” were published in 2007 and 2008, along with the English version “Growing Kids with Character” and “Growing Kids through Healthy Authority” in 2009.

In 2008 she was accredited by OTI Consulting (Singapore) to present DiSC profile workshops, team building seminars, Team Dimensions and Time Mastery.

Hettie is the developer of the Evergreen Parenting Course and heads a group of more than 200 facilitators in 8 countries who use the course to help families. She also does temperament research which lead to the development of Tall Trees Profiles, the first set of locally researched and validated personal and leadership profiles for use in schools, companies, churches and families with the aim to strengthen relationships through a better understanding of individuals and their interaction with others. Along with Annatjie van Zyl she trains facilitators to present Tall Trees workshops locally and abroad. This team has also grown to 130. Hettie’s passion is to see families rebuilt and strengthened. Her books, talks and courses are aimed to inspire, equip and bring families closer to the truths that bring true healing in individuals and relationships. Therefore, she addresses deeper issues than just discipline and parenting. How to live without fear, overcoming trauma and abuse, finding joy and hope after loss, and related topics are also close to her heart.

In 2011 she published her book Vreesloos Vry (Fearless.Free.) about her and Louis’ experiences surrounding the robbery and rape they survived in 2010.

Her recent parenting book Kweek Dissipline met Deernis (Compassionate Discipline) saw the light in August 2012 and deals with all aspects of discipline, at home and in schools. The online Compassionate Discipline System for schools is based on the information in this book and is an invaluable tool for schools. It has recently been approved by the Minister of Basic Education for roll-out into schools as part of a programme to combat violence, learning delays and classroom disorder in 200 targeted pilot schools across South Africa.

The New English version of her highly acclaimed Kweek Kinders met Karakter, Growing Kids with Character 2.0 deals with her temperament profiles or ‘tree types’, which are known for their effectiveness in determining temperament types and how to discipline, encourage, prune and grow each individual child.
