Local and genuinely in your corner
Callahan Computers was founded right here in Decatur to give local businesses an honest, fast alternative to big-box repair counters. After years in the IT trenches, I got tired of watching companies lose days of productivity to slow service and confusing jargon — so I built the shop I'd want to call.
No upselling, no runaround. Just straight answers, careful work, and a real person who picks up the phone.
Questions, answered
Most repairs are completed within 24–48 hours. Many software issues and virus removals are same-day. We'll always give you a realistic timeline upfront when you drop off or during your on-site visit.
Yes. We repair and maintain Windows PCs, Apple Macs, and Linux machines — desktops, laptops, and workstations from all major brands.
Absolutely. On-site support is one of our specialties. We come to your office anywhere in the Decatur area to handle repairs, setups, and network issues so your team isn't hauling equipment around.
Always. Your data never leaves our shop and is only accessed when strictly required to complete a repair. We follow strict confidentiality practices, especially during data recovery work.
