Welcome to
Advanced IT Support
The home of family-feeling technical guidance in Jacksonville and beyond.
Seamless IT, Lasting Solutions
25+ Years of Small-Biz Experience & Technical Excellence
As a small business serving other small businesses, when we say we understand the real-world challenges you face, we mean it.
Our approach is built on more than two decades of helping local companies overcome IT hurdles and advance their operations.
We rely on first-hand experience and the tried-and-tested solutions we’ve seen work – not best guesses and hype.
Our Values
The Stuff That Drives Us
Our core values aren’t just words on a page – they guide every interaction.
We're Real People Serving Real People
We aren't an anonymous voice at the end of the phone, and our clients are more than just a number. Personal, personable service is at the heart of what we do.
We're Understanding of Our Clients' Time
We know you've lost enough hours to IT issues, so when you tell us what needs fixing, we listen.
The solutions we provide are based on a genuine understanding of what will benefit you, specifically.
We Treat Others How We Want to Be Treated
It's basic, but it's fundamental. We act as though we're helping our own business, our own team members, or our own long-time friends: with respect, honesty, and care.
We Do Whatever It Takes
Making it happen means making it happen - period. If it takes us a little more time, some serious research, or going all the way back to the drawing board, then that's what we'll do.
Leading Partnerships, Local Service
While we maintain partnerships with industry-leading technology providers (like Dell, Intel, and Microsoft Azure) to secure our clients the best IT at the best rates, we’ve never lost focus on what matters most: providing personal, neighbourly support to Jacksonville’s thriving business community.
We limit new client intake to ensure every business gets the attention they deserve. With dedicated support and a tech stack unique to you, Advanced puts our clients in the best position to succeed.
