At GSW, we are dedicated to building a diverse, inclusive and authentic workplace. If your past experience doesn’t align perfectly, we encourage you to apply anyway. At times, we will consider transferable skills from previous roles.

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.
