Oz is a Microsoft Excel MVP and YouTube personality at the channel: Excel on Fire. 

His Excel videos are known for being bold, brash, and dramatic, and his passion for clean data and effective use of Excel are always present.

After a layoff in 2008 Oz started freelancing as an Excel developer, and teaching Excel workshops. This exposed him to a wide variety of data-related needs in businesses of all sizes, and in many industries. What eventually became clear was, “without clean data, there is nothing. No dashboards, no analysis, no insights, no nothing!” Thus, everything Oz does with data is rooted in concern for data quality, data literacy, and in service of the people who have to live with the consequences of our data stewardship.

Oz co-authored Guerrilla Data Analysis 2nd and 3rd Editions with Mr. Excel, Bill Jelen. Oz is also a popular instructor with courses at LinkedIn Learning. 

Oz lives in Portland, OR; is a veteran of the US Navy, and is in a documentary about sriracha hot sauce, Sriracha: a Documentary by Griffin Hammond.
