I qualified as a certified public accountant (CPA) 20 years ago. I have a lot of experience across a broad range of industries and sectors, including accountancy, business management, process improvement, internal audit and operations management and training. While working as a financial controller, I noticed a skills gap among accountants in the area of Excel. I created my first Excel course in 2010, aimed at professionals looking to upskill. Teaching Excel became a passion and soon after I launched the blog TheExcelclub.com. I am now proud to say that 90,000 students from 168 different countries have taken my courses.
