For decades, Castleberry Services built and maintained mission-critical network infrastructure for Fortune 500 companies and government agencies across the country. Now we're bringing that same expertise directly to businesses in Lufkin, Nacogdoches, Livingston, and throughout East Texas.
Most IT support companies learn on the job. We came in with 25+ years of large-scale, high-stakes infrastructure experience — and in 2026, we made it available to the businesses right here in our own backyard. Whether you need day-to-day IT support, a secure network build-out, or a partner who can handle whatever comes next, Castleberry Services brings Fortune 500 expertise to your front door.
From structured cabling and server management to business phone systems and risk mitigation, we handle everything so you can focus on what matters most: growing your business.
Local technicians available when you need us. We're in your backyard, not a call center in another time zone.
No upselling, no runaround. We tell you what you need, what it costs, and we deliver on our word.
About Castleberry Services
Castleberry Services started where the stakes were highest — designing and installing mission-critical cabling and network infrastructure for Fortune 500 corporations and government entities across the United States. That work demanded precision, accountability, and the ability to deliver under pressure.
In 2026, we expanded into managed IT services — not because it was a trend, but because East Texas businesses deserve the same level of expertise that national enterprises have relied on for years. Today, we provide local businesses with hands-on IT support, cybersecurity, and network solutions backed by an infrastructure pedigree most MSPs simply don’t have.
When you work with Castleberry, you’re not getting a startup still figuring things out. You’re getting a team that’s already proven itself at the highest level — now focused on helping your business thrive.
