I’m Catherine Llewellyn, and I’ve spent my career learning how the best marketing isn't about the loudest noise, it's about the smartest systems. My professional experience has been a journey through every level of digital marketing. I’ve managed national accounts for big agencies, led high-stakes corporate projects like the re-platforming of water.com, had my marketing copy published on global brand websites, and consulted with business owners on SEO and eCommerce solutions. My purpose is to bring this same enterprise-level "big picture" strategy and seamless execution to small and mid-sized business owners. At Vast Interactive, I act as your Strategic Lead. Think of me as a "second brain" that audits your data and handles the creative execution and digital marketing systems across your Website, SEO, Email, Social, and Creative.
I’m here to take the guesswork out of your growth, building practical systems so you can get back to what you do best: running your business.
