Jeff Stelmach

President, Mosaic Experiential Marketing U.S.

As President of Mosaic US Experiential Marketing, Jeff is responsible for continuing to lead the recently explosive US business. Since joining Mosaic in 2008, Jeff has lead the team through exponential growth, winning an impressive roster of clients including Microsoft, GSK, and Dell to name a few. There is little in brand-focused consumer marketing that Jeff hasn’t experienced over his 20+ years in the industry; from leading integrated consumer promotions and directing award winning experiential marketing campaigns, to building new marketing discipline capabilities within leading agencies in North America. That coupled with his experience across multiple categories, including technology, communication, CPG, automotive, beverages, retail and B2B, position him well to continue to grow Mosaic Experiential capabilities in the US market. .

Prior to Mosaic, Jeff was instrumental in leading the development of Ogilvy & Mather’s Experiential Marketing capability.

Jeff holds a BS in Business/Marketing from University of Notre Dame.
