DMiller Tech started as D. Miller Associates — founded by David Miller, who combined hands-on construction experience working for a plumbing contractor with deep expertise in information technology.
Since 1992, we've been an AMSI and Infor Business Partner, guiding more than 300 construction firms through software selection, implementation, training, and ongoing support. When GEAC was acquired by AMSI, and then Infor, we were there through every transition.
Today, under the DMiller Tech brand, we've expanded our services to meet the full technology needs of small businesses in the region — from cloud solutions and Microsoft 365 to hardware sales and cybersecurity.
"We have been using D. Miller & Associates for hardware and software support for over 20 years. We use their services for purchasing equipment, virus issues, disaster recovery, and construction software. D. Miller has always been quick to respond with support including onsite training. I highly recommend them."
"D. Miller Associates has been extremely helpful. We have been dealing with their office for 10 years and highly recommend them to anyone looking for reliable IT and construction software support."
"The team at DMiller Tech knows construction software better than anyone we've worked with. When we moved to StarBuilder, they handled every step of the transition and made sure our whole staff was trained and confident. Outstanding service."
"We've been through multiple software upgrades and every time, DMiller Tech was there to make the transition smooth. Their knowledge of the Infor ecosystem is unmatched. They respond fast and actually fix the problem — not just patch it."
"When our server crashed on a Friday afternoon, DMiller Tech had us back up and running before end of day. That kind of response is rare. They treat your business like it's their own. We wouldn't trust anyone else with our IT infrastructure."
"We switched to SERVICOM with DMiller Tech's help and the process was seamless. They trained our entire accounting team patiently and were available every step of the way. The follow-up support after go-live is what really sets them apart."
"I've worked with a lot of IT vendors over the years. DMiller Tech is different — they actually understand construction. They know what job costing is, they know what a subcontractor needs, and they speak our language. That's invaluable."
"We've purchased three workstations and a server through DMiller Tech over the past few years. Every time, the pricing was fair and the setup was done right the first time. Simple, honest, reliable — exactly what a small business needs."
"Our firm has relied on DMiller Tech for cloud backup since 2018. When we had a ransomware scare last year, we recovered everything within hours. Peace of mind is not something you can put a price on — but their rates are very reasonable too."
