About

I’m Katherine Mestousis, a strategic communications and marketing leader with extensive experience in translating complex ideas into communications strategies and 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, such as the Center for Disease Control (CDC) and the City of Houston.

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

I thrive in fast-moving environments where I can guide narrative strategy, manage global communications projects, and elevate brands. Whether leading a campaign reaching millions or managing behind-the-scenes transformation communications, I focus on clarity, collaboration, and measurable outcomes.

Additionally, as a dual U.S. and Greek citizen, I bring not only a global perspective, but also the legal and logistical readiness to relocate within the EU.

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