Great service!

15:45 21 Sep 21

We have been working with Computers Nationwide on several Projects at 3 locations. They have been informative, attentive, and patient as we work thru our needs. They have made supportive criticisms both to what we need and what they feel we do not. Love working with them!

When we have an issue they are a phone call away and they always solve our problems.

I will admit that my review may be biased because I am employed here. I have been employed with the company for 25 years. I think that says something about a company. I have worked with numerous talented people throughout the years. We have had, and continue to have, a great team of dedicated professionals.CN has developed a reputation for providing great service to our clients. Our support staff genuinely care about our clients and their staff. I continually hear positive feedback from our clients with regards to how nice it is to work with our support team.Our business has changed over the years and admittedly we are not a fit for everyone. We have developed and grown our managed services platform to bring great value to our business clients and develop long lasting relationships with them. We strive to earn their trust and to become their trusted advisors regarding all things IT.If you are in need of good people, who will have your back and take care of your IT needs with the care that they have for their own, then don't hesitate to give us a call.

Great customer service and knowledgeable technicians. Very responsive to customer needs. Excellent service overall.

Computers Nationwide (CN) provides quality service at a good value. CN has well-trained, responsive staff and well-developed partnerships with vendors in various technical fields (i.e. phone, security, cabling, etc.). I feel confident our company is in good hands with CN's IT oversight.

We've been working with Computers Nationwide LLC for over 10 years. They are a great group to work with and are always very responsive! We've worked with them on IT maintenance, phone system install and servicing, exterior security camera system installations and maintenance, etc. They're always very professional and know their stuff. We've recommended them to some of our tenants for their low voltage wiring installation and IT services in the past and won't hesitate to continue to do so.

21:56 17 Dec 20

Always friendly service! They get the job done with a smile and are very responsive to our needs and requests. It's a great business to work with!

The team at Computers Nationwide is always proactive in thinking of what is best for our company. They offer a broad range of services and their staff is responsive and knowledgeable. I encourage you to contact them to find out for yourself what a great partner they will be.

Dave & Jon at Computers Nationwide have been super helpful from start to finish. I am the owner of Mainstream Boutique in New Lenox and during our build out, Dave always came to us.. We never had to go to his office. First initially to meet us and go over plan options and then he would come periodically to check on progress. Both Dave & Jon stayed in great communication during the install and then showed us how to operate everything after the install was complete. Dave even came onsite one time to help with the POS/software install for Mainstream (which had nothing to do with the work they were providing us). We now have security, phone, & internet all through Computers Nationwide. I highly recommend this company as they do great work and they genuinely care about you and your company.

16:06 28 Aug 20

Computers Nationwide has been a great partner. Currently we use their services for access control and surveillance throughout multiple facilities and could not be more pleased. I would reccomend this company to all. Keep up the great work Jon & Dave !

I have struggled through a computer issue for 7 months before bringing in Computers Nationwide. They quickly identified 3 things to do immediately to help solve the issue. Within two weeks of upgrades and changing out some components the system was stabilized. I would recommend them and wish I had called them sooner.

15:35 24 Jun 20

We have used Computers Nationwide for security cameras and a door lock system. Mike, our sales guy is always helpful and goes out of his way to make sure things get done. The installs have been quick and they have been helpful with the few problems we had.

21:17 22 Jun 20

I have worked with computer Nationwide for over 4 years and highly recommend them to everybody . They are always there when you need them and staff is very very professional . They are also improving and finding new technology and advancement and bringing ideas . Very good people

I have worked with Steve Cepican from Computers Nationwide for over 10 years. I have a large real estate portfolio with tenants who constantly have data/cabling/IT/security needs and Steve never disappoints. They are very responsive, always competitive with pricing, and I have never had a tenant complain about their work. I would highly recommend them to anybody.

Best in the business.

I've been using Computers Nationwide for years and would highly recommend them. They are very knowledgeable , prompt and pay attention to my needs. They are very responsive and help me solve any new projects that come up with solutions that have worked well to help me grow my business. 5 stars all day long .

David was a great Tech to work with. I was having problems with my software and he was able to troubleshot it and help resolve the issue remotely (I'm in Pennsylvania). He was very patient with me, as I'm not very tech savvy. He was super personable too. Every time, I need help they make time to help me and always make me feel important. Owning a smaller trucking company, it's great to know I can rely on companies like CN to help with my IT services.

18:46 29 Nov 18

Great people, great response time, and a vast knowledge in the IT world

02:45 07 Aug 18
