Why our clients trust us

I have worked with Chicago Computer Network team for over 15 years; they maintain our servers and desktops. We never have to worry about anything because most work is done remotely, all problems are noticed and fixed before we even know that there was something wrong.

Chicago Computer Network team works well with vendors and became our single point of contact. I would highly recommend them.

Working with Chicago Computer Network is so refreshing. For the first time our company’s IT needs are met and sensitive data is secure. Besides quality service, we have been so happy with accessibility to support. It’s refreshing to get a call back in a reasonable amount of time. Since switching to Chicago Computer Network over a year ago we have recommended them to another mid size company and heard they’re working out great. Thanks Jarek, for providing IT the way it should be!
