Our Story
We're Grace and Erik, and we live in British Columbia, Canada. Grace graduated with a computer science degree and spent several years working as a software engineer. Erik is a financial analyst and tech enthusiast.
When we bought our first home, we were surprised at how hard it was to find transparent answers about our money. This kickstarted Green Flag Wealth, where our mission is to make personal finance transparent and accessible to everyday Canadians.
