About

I’m Katherine Mestousis, a strategic communications and marketing leader with over 13 years of experience translating complex ideas into campaigns that drive impact. I’ve led high-visibility initiatives for organizations ranging from global brands like Google and Live Nation to government agencies and public health nonprofits.

My expertise spans digital storytelling, project management, stakeholder engagement, and change management—delivered across remote, hybrid, and cross-cultural environments.

As a dual U.S. and Greek citizen, I bring not only global perspective but also the legal and logistical readiness to relocate within the EU. I thrive in fast-moving, remote-first teams where I can guide narrative strategy, manage global communications projects, and elevate mission-driven brands. Whether leading a campaign reaching millions or managing behind-the-scenes transformation communications, I focus on clarity, collaboration, and measurable outcomes.

Let’s connect if you’re looking for a results-driven marketing and communications partner who can lead from anywhere—and deliver everywhere.
