I’m Catherine Llewellyn and I founded Vast Interactive Consulting in 2007 to give growing businesses access to the kind of strategic marketing that usually only national brands can afford.
My marketing career started at traditional and digital agencies, working on accounts like BMW and Cingular Wireless at BBDO. This corporate path took me through strategy and account management roles for Home Depot Canada, IHG, Georgia Department of Economic Development, and Equifax. After seven years in that world, I saw a gap: sophisticated, fully-managed digital marketing wasn’t accessible to smaller companies. So I built a consultancy to close it.
What I do differently is simple. I don’t sell you a dashboard and call it a managed service. I develop the strategy and provide personalized service to implement it — no layers, no handoffs, no corporate overhead that inflates your invoice without improving your results. You and I work together directly.
My focus is to create a sound digital marketing system that grows your business. This includes content strategy, SEO, lead generation, CRM, and paid media with specialized experience in HIPAA-compliant marketing for health, wellness, and senior living clients. I hold a HIPAA content certification and have been recognized as Digital Marketing Consultancy of the Year by Corporate LiveWire.
If you’re ready to simplify your digital framework, solve a specific marketing challenge, or want to debate Duke basketball with an alumni, let’s connect. Schedule a Discovery Call, send me an email, or find me on LinkedIn.
I don’t hand you a dashboard and disappear. Every partner engagement is hands-on, data-driven, strategy-first, and built around what your business actually needs right now.
A direct look at your numbers, your tech stack, and where your marketing is leaking. Whether that's a focused 90-minute Strategic Marketing Plan session or a live 1-on-1 Coaching intensive, we find the bottlenecks and fix them fast.
Clean engineering and strategic content work together to make your site easy to find — on Google and in AI-generated recommendations. I make sure your technical foundation is solid first, from database migrations to schema implementation, then layer in the SEO content strategy that builds lasting authority.
Writing and design that fits your brand voice and proves your expertise. I build your complete content authority framework from the ground up — advanced copywriting, custom graphics, page layouts, and visual styling — strategized, directed, and quality-controlled by me.
Targeted campaigns that scale lead volume without agency overhead. I handle the full lifecycle across channels — audience targeting strategy, ad and content creation, landing pages, launch, and ongoing management — whether that's paid search, social media, CRM, or programmatic.
Your contact list is already a business asset — it just needs activation. I handle everything from list segmentation and template design to automated nurture sequences that connect directly to your lead generation setup.
If you’re ready to turn your digital fragmentation into a cohesive growth engine, the process starts with a simple conversation. We don’t do high-pressure sales; we do research-backed strategy.
1. Discovery Call We’ll discuss your current marketing ecosystem, your business goals, and where you feel the “gap” is currently widest.
2. The Audit If we’re a good fit, I’ll dive into your analytics to find the untapped opportunities and the bottlenecks costing you leads.
3. Implementation Roadmap I’ll present a practical plan that I will personally launch and manage to ensure your business reaches its KPIs.
