My Story

With two decades of experience in the intense worlds of media, gaming, tech, B2B, retail and consumer, I help brands find their voice when the stakes are highest. Whether it’s launching a brand-defining moment, navigating a messy corporate pivot, or figuring out how to make AI work for an organization, I thrive on turning complexity into clarity. 

Having served as a Chief Communications Officer for business units generating $10B+ to $100B+ in revenue, I bring a unique perspective on how to align multi-disciplinary teams behind a shared vision. Curious and creative, I shape compelling, culturally relevant narratives and communication strategies that improve relationships, results and reputation.
