View profileBehavior-change communications agency integrating research, PR, multicultural strategy, creative, digital and paid media.

C+C is a communications and behavior-change agency founded in Seattle in 2005. Its teams combine research, public relations, multicultural communications, digital strategy, creative production and paid media to move audiences from awareness toward measurable action.
The agency has a distinctive position in public-interest and values-led marketing. It is particularly relevant for government bodies, utilities, nonprofits and mission-driven brands that must explain complex issues and produce observable changes in public behavior.
C+C integrates paid, earned and owned channels from a common behavioral strategy. Researchers, PR practitioners, multicultural specialists, digital strategists, producers and creatives work together on public-information and social-impact campaigns.
Documented strengths include public health, recycling, water conservation, energy efficiency, transportation safety, education and environmental behavior. These sectors require evidence-based audience segmentation and accessible communication across diverse communities.
Seattle, Portland and Boston provide coverage across the Pacific Northwest and East Coast, while campaign work is delivered nationally. The footprint suits United States programs that need regional insight plus centralized creative and measurement.
A human editor reviewed C+C’s site and PRSA records. The evidence consistently connects the agency with measurable public-interest campaigns and professional recognition, including work for public-health clients; review-platform commentary was not used.
PRSA records identify C+C’s work with the Washington State Department of Health on the Spread the Facts campaign as Best of Silver Anvil. The agency also publishes a 20-year operating history and hundreds of awards.
Technology signals include audience research, digital strategy, paid-media management, campaign measurement and multi-channel production. No proprietary software platform was publicly documented.
C+C differentiates through behavior-change discipline and social-impact specialization. The agency’s value is not simply publicity volume; it is the integration of research, cultural insight and channel planning around a defined public action.
Compared with generalist PR firms, C+C offers deeper behavioral-science and public-information experience. Compared with pure research consultancies, it can carry the insight through creative, media, digital and community-facing execution.
