Microsoft Excel MVP & Evangelist for Clean Data
Known for my hats and bowties, my true mission is about clean data. I've been using Excel as my main weapon against crap data for about 15 years. It's helped me to end all manner of mayhem and strife caused by duplicate profiles, incomplete lists and messy processes. Over the past few years, I've done more teaching and speaking, and recently wrote Guerrilla Data Analysis 2nd Edition, with Mr. Excel, Bill Jelen. Today, I live in Portland, OR after 19 years of living in Chicago.
