DDK Finds Answers and Solutions
My company is totally dependent on voice and data communications—so it has to be working! DDK’s priority is to keep their customers’ equipment and services up and running, when something breaks, they get services restored promptly.

We provide B2B services to business owners since 1979 for cashless transactions. DDK first provided computer tech service to us over ten years ago. My company has been a pioneer in using VoIP, and DDK has succeeded, where other providers failed—to provide continuing low-cost voice solutions.

DDK’s service is beyond typical tech service as they educate customers, (who want it) about their equipment and services, helping them understand how to equip their business and implement procedures to deal defensibly against service and mechanical breakdowns. I am not an average customer for techs and have tendered complex issues to Dennis Krohn, and he leaves no rock unturned to find answers or new solutions.

Keeps Us Working Efficiently
When we suffered “the blue screen of death,” with a computer crash, a friend recommended DDK Communications. Dennis Krohn first focused on finding what we had lost, thus rescuing the computer user. He also has helped our private K-12 school get our computer labs updated. Not only did he get us the right equipment, he made sure it was all protected properly.

Dennis remotely maintains our equipment and backs up our data every night, giving us great peace of mind. He’s so knowledgeable and helpful—we’d highly recommend him.

Watches Out for Our Best Interests
In the 10 plus years we’ve depended on Dennis Krohn of DDK Communications, he has saved us money and time. All our workstations are networked, our virus protection kept updated. As a point-of-sale ticket broker, our website MUST work 24/7. Dennis makes sure our software is compatible, working remotely to keep our software and hardware working. He is proactive anticipates situations, preventing them from becoming problems. Our confidence level in Dennis is very high—and we’d recommend him because he is always on top of things, watching out for our best interests in serving our customers.

DDK Kept School’s Computer Running
The best part of working with DDK and Dennis Krohn was that we didn’t have to worry about things—he was on top of everything, and he did it most often from a remote location. Sometimes it was easiest if he came to our school and fixed the problems, and he did that usually within a day of our call. We liked knowing that he’d update and back up our day’s work after the school closed for the day.

When we had to purchase new laptops, he thoroughly researched the options and helped us get the best deal. With so many students using our computers, one of our biggest issues was having enough memory.

We appreciated that DDK was quick to respond to our work order, email or phone call, keeping our technology current and our equipment maintained. We have a great working relationship, and we’d highly recommend DDK to anyone needing a company they can depend on.

19 Years of Exceptional Computer Service
I have relied on DDK as my technology guru for the past 19 years. DDK always keeps my hardware and software working at full efficiency, and Dennis and his team are available for any computer crises I’ve had over the years. In addition to maintaining my equipment and software, they advise on products and services I should have, and are always on top of security issues to maintain the safety of my business technology.

If Dennis thinks I need to update equipment or software, he’ll proactively research and advise me. And, one of the best features over the past few years is that DDK can resolve computer issues remotely. I trust Dennis Krohn because of his knowledge and integrity. I often think, “What would I do without him?”
