Chong + Koster is a media firm in downtown Washington, DC that specializes in digital communications for high-profile clients. We work with major brands and (progressive) political clients. Chong + Koster is a full-service firm, with in-house ad creative, ad buying, strategy, web design and development. We were the first firm to publish a comprehensive voter persuasion model for the internet, the first firm to prove online ads can move poll numbers on their own, and the first firm to win a statewide election using online ads as the primary form of voter communication. We are a boutique ad shop dedicated to high-quality service. We also pride ourselves on being a tight-knit team of professionals that really like each other—it's a fun place to work.
