Welcome to Spreadsheets for the People! My name is Dennis Osorio, and I created this website to serve as a collection of free tutorials for empowering everyday people.

Among other things, I like math, data, spreadsheets, and computers. My goal is to spread knowledge and interest in these things, to challenge myself to become a better writer (or at least to do more of it), and to contribute something interesting and relevant to the public.

If you have arrived here and really need to get your spreadsheet problems or frustrations fixed, I am available for consultation.
