I have been using Excel for over 20 years, with experience primarily in the field of accounting, though I've also utilized Excel in more creative directions e.g. setting up diagrams to aid teaching and understanding. (There's a lot you can do with Excel that doesn't necessarily involve numbers!)

What clients say
Real beginners. Real confidence gained.
I'd been pretending to know Excel for years. After three sessions I actually do — and nobody at work has any idea I needed help.
Robert is unbelievably patient. He took the one thing I couldn't figure out and made it feel obvious in twenty minutes.
I came in nervous and left with a working spreadsheet I actually understood. Worth every dollar.
