Gary Slack 
Chairman
Chief Experience Officer
Gary finds ways to achieve his goals. He started Slack and Company (then under a different name) back in 1988 with just one client. During a recession. While his wife was pregnant with their second son. This year, Gary is celebrating the agency’s 24th anniversary.
Gary has earned several Agency of the Year nods, not to mention landing on BtoB Magazine’s list of the “Top 100 Influential People in Business-to-Business Marketing.” But to him, what matters most is developing strong brands and achieving measurable results for his clients.
Before he founded the agency, Gary spent 11 years in senior management roles at Omnicom agencies Doremus & Co. and Porter Novelli. Fresh out of college, he worked as a reporter for a newspaper in his native New Mexico.
Gary is also involved in the local business community, most notably as two-time past president of the Business Marketing Association’s Chicago chapter. And he served as chairman of BMA National’s executive committee for the 2009-2010 program year. He’s also on the boards of both the Economic Club of Chicago and the Chicago Council for Science and Technology. Oh, and if you ever find yourself at the Chicago Botanic Garden on the weekend, keep an eye out for Gary, hunched over one of the garden’s rarer specimens.
