Most of the handy Excel tools and tricks I use day to day in my role as a Senior Engineer, I learnt from Garry over a decade ago when I was a grad student doing a project for Garry's employer, where he was Network Information Analyst. So, it is based on my first hand experience that I highly recommend Garry as a tutor on not just MS Excel, but many areas in Statistics and Data Science. Later, as a member of the team that Garry was part of (Electricity Network Planning), I was also the beneficiary of Garry's great and innovative work in data cleansing -of electricity demand data, electrical asset data etc.

Garry is an excellent Excel tutor. He helped me build a powerful and intuitive excel model, which is still in active use by a Big 4 firm — a testament to the quality and reliability of his work. His patience, ability to simplify complex concepts, and clearly explain the design process and underlying formulae made him an excellent tutor. Highly recommended.
