I've shaped executive and internal communications at Socure, Alteryx, SpaceX, and The Walt Disney Company, helping leaders translate business strategy into clear action during growth, transformation, launches, and M&A.

At Socure, I rebuilt the internal communications function into a scalable operation spanning executive messaging, employee engagement, change communications, and enterprise channels. I increased monthly enterprise communications output by 21% without additional headcount and built measurement systems to continuously improve engagement.

At Alteryx and SpaceX, I advised senior leaders, ghostwrote high-stakes communications, and led global all-hands, keynotes, and employee channels for technical organizations. My work improved leadership social engagement by 50% year over year, raised internal executive engagement scores by 10%, and reached more than 5,000 SpaceX employees weekly.

I also bring a publishing and publicity background from Disney, where I led campaigns for Pixar, Marvel, and Lucasfilm titles and helped drive more than 20 books to New York Times bestseller status. I combine storytelling, sound judgment, and data-informed communications practices to build credibility and alignment in complex organizations.
