As a journalist and former intern for The Water Desk, Greg Ramirez approaches the craft and study of environmental journalism with relentless curiosity. His professional career, which spans multiple industries and cities, started in public relations, where he worked in the National Hockey League for both the Dallas Stars and Nashville Predators. In those roles, he worked closely with front-office executives and athletes to promote the on- and off-ice endeavors of each club. Later, in Seattle, he helped an architecture firm shape a new identity as they repositioned themselves in the Puget Sound region.
