From our earliest days, we’ve been proud to represent organizations of all sizes on a national playing field. Every client has national as well as local needs — whether for awards and speaking engagements, trade media coverage, top-tier media coverage or digital services. From our headquarters in Boston, we can score coverage across the country or across the street. And with the added benefit of having access to boots on the ground nationally as well as internationally, through our proprietary network of independent partner firms within Public Relations Global Network, our clients can have access to detailed, insider knowledge about key targets and communities anywhere in the world.
