Hi, I'm Mr. Coleman.

I'm Dave Coleman, an IB Business Management teacher in Livermore, California. I built this site to help my students practice real business thinking — marketing, finance, entrepreneurship, and strategy — with clear explanations and 290 study flashcards.

My class explores how businesses actually work: the 4 Ps, SWOT, STEEPLE, Ansoff, Porter's Five Forces, break-even, cash flow, and more. The goal isn't to memorize — it's to practice, practice, practice.
