Learning to see the world differently

It was an amazing school and I have very fond memories of it. St. Dominic’s made me appreciate different cultures, views and countries and if it wasn’t for that school I would definitely not be the person I am today.

A home away from home

SDIS played a very important part in moulding me into the person I am today, not only by the excellent education it gave but the fact that we had teachers that truly cared for what we did and nurtured our minds and wills, to always go further.

Learning how to learn, without fear

St. Dominic's was a very important school for me and I hold my experience there very close to my heart. I was very happy there. It was a school that took me away from the parrot teaching I experienced in my previous school.

More than a school, a family

To me SDIS was both a home and a family. Having spent 14 years studying at SDIS was the best experience I could have ever asked for. People, who built an environment so natural to thrive in and an education system that did not restrict, who you were, but instead helped guide you in the right direction.

Where diversity shapes identity

Being in a multicultural atmosphere at such a critical age helps you grow into an awareness of the importance of being part of something culturally bigger than you as an individual but also still cherishing what makes you, you.
