David H. Ringstrom, CPA has worked as a spreadsheet consultant for almost 30 years.  Early in his career as an accountant, David recognized the tremendous untapped potential to automate the accounting workplace using spreadsheets.

After overcoming his love for Lotus 1-2-3, he became an Excel enthusiast, learning the program’s many “hidden” features and combining those with his accounting knowledge to unlock Excel’s true power to streamline accounting work.  Through his consulting work and years of feedback from clients and other Excel users, David has developed a keen sense of what most users don’t know about Excel – but should, and so that’s what he teaches. 

Today, he is an author and  nationally-recognized authority in Microsoft Excel, presenting over 200 live continuing education webinars to thousands of professionals each year.  He has spoken at numerous conferences, written hundreds of freelance articles on spreadsheet development and Microsoft Excel, and his first book, Idiot’s Guides – Introductory Accounting, was published in 2016. He’s currently working on his second book.
