Few agencies have do-gooding written into their DNA as much as TDA_Boulder in Boulder, Colo. But this 25-person shop proves that wanting to communicate and inspire change in society isn't just good for the soul, it's also good for business.

Under CEO Thomas Dooley and Executive Creative Director Jonathan Schoenberg, TDA brought in $20 million in revenue last year; saw its own natural-condom company, Sir Richard's, hit the shelves in drugstores nationwide and make donations to Haiti; and helped clients like Justin's Nut Butter and Izze Soda launch brands. All the while, it also kept growth steady for all-natural food companies French's and General Mills' organic division. The agency also counts among its clients one of Wall Street's hottest public offerings this year: pasta chain Noodles & Co.

These accomplishments have helped fuel a low turnover rate and an average employee tenure of six years -- almost unheard of in the ad business.
