Our Story

Avocado Lab was founded by a group of parents who, like any of you, wanted the best for our kids.

Coming soon!

Why Avocado Lab is named Avocado Lab

We wanted a fun, memorable name that will resonate with kids. (and it starts with A like Apple, Amazon or Alibaba) or perhaps it was mere coincidence that Garry had been drinking a lot of Avocado milkshakes around that time. You get the idea 🙂


Garry sees himself as a coach for young talents who are curious about the world around them. His unique mix of theory, practice and creative thinking has helped many of his students excel in various tests and competitions, including the GEP selection test and Math Olympiads.

His classes are often full of discussions about the connections between math, science and the world around us, and heated discussions among students about whose solution is more elegant.

While he seeks to achieve academic and competition excellence for his students, he considers it even more important that his students learn about grit, humility and thinking outside the box. He is also familiar with the MO competition scene and believes in harnessing the best resources and materials available worldwide. He has also conducted robotics and programming classes using the micro:bit and Arduino platforms both locally and overseas.

Garry has 2 GEP kids and a Masters in Business Administration (MBA) from the National University of Singapore (NUS). Previously in technology management, he first dabbled in Math Olympiads after having difficulty finding help for his children, and thus decided to do the teaching himself.
