Esther Zimmelman

I’m an internal communications leader with extensive experience driving strategy for global, distributed organizations. I specialize in translating complex business changes into clear, compelling employee narratives using executive messaging, intranet platforms, and live & virtual events.

I built and owned the internal communications function at two companies of 800+, partnering with the executive team and cross-functional leaders across HR, Finance, Technology, Legal, and Risk. I architect communications programs from strategy through execution, and I’m especially focused on measurable engagement outcomes.

At FIRST Agency, I achieved an 85% engagement survey participation rate by building repeatable systems for leadership. I also spearheaded a global intranet rollout (Simpplr), sustaining 80%+ monthly employee logins, and increased participation and engagement by 20% through content strategy and end-to-end production of quarterly town halls and business reviews.

I bring strong leadership and operational rigor to change, crisis, and content work—covering speaker preparation, logistics, and budget ownership. I’m energized by mentorship and by shaping initiatives like Diversity & Inclusion Council communications, turning strategy into experiences people can feel.
