About

I build social strategies that make B2B brands feel human. Over the last decade, I’ve led organic social, storytelling, and content strategy across tech, healthcare, nonprofits, cultural institutions, and global brands — helping companies turn complex ideas into conversations people actually want to engage with. Today, I shape organic social strategy work at Atlassian, where I help build campaigns, editorial narratives, executive storytelling, and product moments across channels that reach millions of people. My work spans everything from AI product launches and building cross-organizational creator programs to customer storytelling, event amplification, and data-driven content strategy. I’m especially passionate about finding the intersection between audience insight, brand voice, and creative experimentation — the sweet spot where content stops feeling like marketing and starts building community. Before Atlassian, I led social strategy for VMware Tanzu, managed international marketing campaigns in Germany, supported public health and crisis communications during COVID-19, and consulted for brands including Microsoft, Uber for Business, Calendly, Nutanix, and more. I’ve also spent time working in museums, for festivals, nonprofit fundraising, publishing, and community education — experiences that continue to shape how I think about storytelling, accessibility, and audience connection. At the core of everything I do: ✨ Strategic thinking grounded in analytics ✨ Creative storytelling rooted in empathy ✨ Building systems and processes that help teams work smarter ✨ Making B2B marketing less robotic and more memorable ✨ Shaping and nurturing the creator-led landscape of organic social Let’s connect if you care about thoughtful marketing, digital storytelling, building the creator economy, social strategy, AI-enabled creative operations, or building brands people genuinely want to follow.
