I gained my experience teaching and working with Excel as a freelancer for medium and large-sized organizations such as ING, NN Investment Partners and Pfizer. 

Besides, I have a master's degree in Digital Business & Innovation, where the majority was about big data, analytics and business intelligence. 

During my experience, I learned what Excel features have been most valuable for people working in larger organizations. Besides, adopting the right way of working with Excel, unleashes it's full potential and helps you gain insights you wouldn't expected to have gained through Excel. 

In my classes I walk you through some of Excel's most amazing features, but also some very basic tips and tricks that help you become an Excel master!
