Working with and helping people of all ages has always been my passion. I graduated with a degree in Human Movement Science from the University of Pretoria in 2012 and further obtained a degree in Physiotherapy from the same institution in 2016.

Currently I am practicing as a Physiotherapist working with both in hospital- and out patients. My main interest is in the Orthopaedic field and the rehabilitation of these patients.

I decided to get involved in the Whartels program as it was an opportunity to further my passion of working with people. The wide variety of concepts and elements within the Whartels program is what intrigued me to find out more. I believe the Whartels program has major potential in its interactive learning framework where learning through playing is emphasized.

I will be involved in the implementation of the Whartels program in the Gauteng region. We are looking forward to making you, your child, and your school etc. part of the Whartels experience!

I am an entrepreneur and business owner for the last 15 years. After registering my first Mining permit in 2006 I had the privilege of exploring this exciting line of business. This journey took me from learning to operate my first excavator to various constructions sites, road building projects, adapting to the ever-changing economic climate, marketing and much more. Resilience was the most important aspect that stood out above everything else.


My passion is to help our youth as I did when doing youth development work after I matriculated while studying Theology. Kids need to learn from a young age to become resilient, learn coping strategies and ultimately be self-starters.


This motivated me to start a Lets Really Play Math’s Centre and help kids to not only see an opportunity, but to be well enough equipped to take it.


As a mother who does home-schooling, I understand the challenges parents face to ensure they give their children a solid academic foundations.


I’m excited to be part of this team and will be assisting with marketing, training and development of centers.
