Excel & AI training for finance, accounting and operations teams

Hi, I’m George. I’m an O’Reilly author, Microsoft MVP, and LinkedIn Learning instructor.

I help finance, accounting, and operations teams get more out of Excel. That means using tools your organization may already have, including Power Query, Python in Excel, Copilot, and Power Automate, to make analysis faster, reduce manual work, improve reliability, and build workflows that are easier to maintain.

I work with organizations through corporate training, workshops, and longer-term engagements designed to help analysts spend less time fighting spreadsheets and more time doing useful work.
