Most IT companies give you a help desk ticket and a queue number. We give you our cell phone. Arlington, TX–based, locally owned, never outsourced — and serving DFW businesses since 1989.
Think about electricity. You flip the switch and the lights come on. You don't think about it — it just works. That's the standard BDunn & Company holds itself to for your technology. We set everything up right the first time, and then it runs. Reliably. Predictably.
Billy Dunn has been managing IT for small and mid-size businesses in the Dallas–Fort Worth area since 1989 — longer than most IT companies have existed. Not through advertising, not through cold calls, not through any of the usual playbooks. Every client we have came through a referral. That track record only stays intact one way: by doing exceptional work, every time.
When we set up a client environment, we do it precisely — the right hardware, the right software, configured correctly from day one. The result is a system that runs the way your lights run. You don't think about it. You just flip the switch.
From your daily email to your network security, we handle every layer of your technology infrastructure — so you can focus on running your business.
Proactive monitoring, maintenance, and support for your entire technology stack. We watch your systems 24/7 so issues are resolved before they become problems you feel.
Multi-layer endpoint protection, email security, network monitoring, and security awareness. We deploy and manage ESET endpoint security and maintain a hardened perimeter for your business.
AI is changing how businesses operate — and we help you use it intelligently. From workflow automation to tool selection and implementation, we guide your AI adoption in a way that strengthens your operation without creating new risks or replacing the expertise you rely on.
Our preferred productivity platform. We deploy, configure, and manage Gmail, Drive, Meet, and the full Workspace suite — including security hardening, admin console management, and ongoing user support.
Full Microsoft 365 deployment and management including Exchange Online, Teams, SharePoint, and Azure Active Directory. We support clients who depend on Microsoft's ecosystem and keep it running cleanly.
We deploy and support Yeastar IP PBX systems with Yealink desk phones — professional, reliable VoIP for small businesses. Feature-rich call routing, voicemail, auto-attendant, and mobile apps included.
Platforms We Deploy & Support
The IT industry has trained businesses to accept slow response times, anonymous help desks, and vendor-of-the-month relationships. We've never operated that way — and we never will.
When you have a problem, you call us directly. No ticket numbers. No queues. No automated phone trees. You get a real person who knows your business — because we've built a relationship with you.
Most IT problems are symptoms — they trace back to something that was set up wrong or never properly configured. We eliminate that at the source. Right hardware, right software, right configuration from day one. When your environment is built correctly, it runs. Your staff stays productive, problems don't pile up, and you spend your time running your business — not chasing IT issues.
We haven't run an advertisement in over 25 years. Every client came to us because another client recommended us. That's the only endorsement that matters — and it tells you everything about how we operate.
We have never resold hardware, software, or licenses — and we never will. Our recommendations are never influenced by margin. When we tell you to buy a Ubiquiti switch instead of a Cisco, it's because it's the right tool for your business. Full stop.
We've built deep expertise serving specific industries in the Dallas–Fort Worth area. We understand the compliance pressures, the workflows, and the risks unique to your field.
Secure, compliant IT environments for financial advisors, CPAs, bookkeepers, and accounting firms. We understand the sensitivity of financial data and build environments that protect it.
HIPAA-aware technology for medical practices, dental offices, and healthcare providers. We configure and manage systems that support protected health information while keeping your staff productive.
Law firms demand reliable, confidential, and always-available IT. We support attorneys and legal professionals with secure document workflows, reliable communication systems, and bullet-proof uptime.
Rugged IT solutions for industries that work hard. We support contractors, manufacturers, and energy companies with practical, dependable technology that keeps pace with demanding operational environments.
Artificial intelligence is transforming the attack surface. Agentic AI systems — autonomous software agents that browse, communicate, and act on their own — are already being weaponized by bad actors to probe, phish, and breach business networks at scale and speed that humans can't match.
Most small businesses have no defense posture for this at all. We do. We stay ahead of emerging threats so you don't have to think about them.
We donate retired business computers to Mission Arlington / Mission Metroplex — a DFW-wide ministry operating at 350+ locations that provides food, medical care, counseling, and Bible studies to families across the Metroplex, free of charge, since 1986.
We don't do hard sells or generic demos. Tell us a bit about your business and what's not working the way it should. We'll have a straightforward conversation and tell you honestly whether we're the right fit.
