About
Meet Diego Castillo, the person behind DC Marketing
DC Marketing LLC was built with one goal: helping businesses grow through simple digital systems that bring in real customers.
My story
I'm a 16-year-old entrepreneur who got into business and digital marketing early, by learning, testing and figuring things out on my own.
A big part of my experience came from helping my dad with his concrete company. I started with his marketing: building websites, running ads, and learning how to bring in steady leads through Google, Facebook and Instagram.
That taught me something important: most businesses don't need complicated marketing. They need simple, well-built systems that consistently bring in customers. So I started DC Marketing LLC to help other business owners do the same, working with you one-on-one from start to finish.
My mission
To make digital growth simple, clear and profitable for business owners, without confusion, wasted time or complicated systems.
Who I work with
Contractors and construction companies, home service businesses, automotive services, cleaning companies, and anyone who wants more local customers.
