About Erin Mariathasan

I’m a strategic communicator, events consultant, and community builder who helps mission-driven organizations engage their audiences with clarity, care, and impact.With a strong background across both corporate and nonprofit environments, I specialize in designing communications and events that build trust, spark connection, and drive results. Whether I’m helping shape messaging in a critical moment, planning a fundraising gala, producing an internal or client event, or advising leadership on stakeholder engagement, I bring a steady hand, clear thinking, and a collaborative spirit.Often described as the “pulse of the organization,” I listen deeply to feedback and understand organizational culture, helping leadership stay connected to the people they serve and work alongside.Previously, I’ve served as a Chief of Staff and Communications Director for a global corporation - roles that honed my ability to lead with both heart and strategy. I believe that thoughtful communication and intentional connection have the power to transform communities and organizational cultures - and I love helping teams bring those values to life.
