Darren is a genius when it comes to building business assessment tools in Excel. There was no off-the-shelf software that did what I needed to do for forecasting. So, I challenged Darren to build from scratch what I needed. He provided me with a brilliant program that he continues to help me tweak. Keep up the great work, Darren!
