GSW is a full-service healthcare communications agency that goes beyond advertising to create personalized brand experiences that involve, inspire, educate and activate people through ongoing brand journeys. As one of the world’s ten most-awarded healthcare advertising agencies, GSW is hell-bent not to replace the same old with the same old. This is achieved through a provocative premise if other brands communicated the way healthcare brands do, how many customers would they have? GSW turns against this premise through discovery of beneath-the-surface customer insights that we impact with stories, simplicity and authenticity. We call it "speaking people."

Building partnerships with pharmaceutical, biotechnology and health-and-wellness clients in 18 major markets around the world, GSW creates marketing solutions through a comprehensive and wide array of services including advertising, digital and closed loop marketing, strategic insight, branding, communications planning, predictive modeling, market access strategies and media and market research.

The agency is led by a team of best-in-class marketers who have experience with a variety of stakeholders such as healthcare professionals, patients, caregivers, payers and consumers.
