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 eCommerce re-design of water.com, had my marketing copy published across global brand websites, and consulted with business owners on SEO and eCommerce solutions that return a positive ROI. I bring this same enterprise-level "big picture" strategy and seamless execution to small and mid-sized business owners.
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.
At Vast Interactive, we believe digital marketing should consistently do what it’s supposed to do: work. Whether it’s driving high-conversion email nurture campaigns or crafting local content that reaches your audiences in the moment, we solve the challenges small businesses face with sharp thinking and seamless creative execution.
