Meet the Team
We have incredibly dedicated, passionate and skilled staff and are grateful for them every day. Our goal at the Centre is to graduate young men and women who are employable and, together with their families, are empowered to deal with their challenges.

Jami Kastner
Founder and Chairman
Jami Kastner is the founder and chairman of the Butterfly Centre, a registered NPO started in 2014. The oldest of her three sons, Jack, has Global Developmental Delay. The Kastner family searched high and low for answers and the right learning environment for their child, but failed to find the right fit. They could no longer watch his confidence erode as they tried to force him through the mainstream school system, and they knew that there must be other parents in a similar position. Now 13 years old, Jack is a student at the Centre. As with the other Butterfly children, the improvements in his learning capacity and general wellbeing have been remarkable.
A family tragedy in 2013 was the driving force behind the start of the Butterfly Centre. In order to honour the life of their youngest son Sam, lost that year in a drowning accident at only 18 months, they started the NPO. The Centre itself was started in a rented premises in Stanford with Jack and just one other boy. In the years since, they have successfully raised enough money to build a permanent home for the Butterfly Centre at Stanford Hills Estate, the Kastner farm just outside the village of Stanford.
Jami was named Overstrand Woman of the Year 2019 for her commitment to helping children who are “different” and her fight for inclusivity and opportunities for all. She is the author of a book entitled Sam and Me and the Hard Pear Tree, detailing her journey with special needs as well as her continued healing and search for meaning in the wake of Sam’s loss.

Vanessa
Teacher
After completing school, I pursued my passion for horse riding, earning my South African colours during a dedicated gap year. My journey led me to study Montessori teaching and start my own riding school, which included therapeutic horse riding for people with diverse needs. Recognizing the physical demands of equestrian sports, I also studied remedial sports massage to support my riders and others during competitive training. My curiosity and love for horses took me to the USA, where I gained further knowledge and hands-on experience. Beyond my equestrian career, I explored agriculture as an orchard quality controller on a blueberry farm where I had the privilege of working with and learning from diverse cultures. This exposure broadened my perspective and deepened my appreciation for people from all walks of life. I’ve always been passionate about working with people and children, and I feel incredibly fortunate to have found my purpose at The Butterfly Centre. It’s a privilege to be part of such a nurturing and inspiring environment where I can contribute to the growth and joy of our students every day.
