Rebecca Holmes

After several relationships with IT consultants/large IT firms that provided either no results or enormous fees, we contacted Mark to consult with us on several network issues and were extremely pleased with his overall value. Mark was knowledgeable on VPN and network issues and was extremely responsive. Most importantly, we feel we can trust Mark to lead us in the right direction with our IT needs and to be fair in resolving issues. I highly recommend Mark if you are looking for an experienced, honest and reliable IT professional.

 

Ron Tessler

Owner at Tessler Construction Company

We have been working with CorporateIT, specifically Paul Hathcock for some time now. What we appreciate most about working with Paul is his ability to quickly solve our issues, if not instantly while we are on the phone, by that evening. He does most of his time consuming computer work after hours so he doesn’t interfere with our work and this keeps everyone happy. He is extremely knowledgeable and what he doesn’t know, he will research, which makes him able to deliver accurate answers to any issue we have had. Their prices are very reasonable however, his service to our company has been priceless.

Executive Vice President/Co-Founder at Windy City Fieldhouse

Mark has done great work for us. He has a strong knowledge of computer systems and IT solutions. He also listens and converts your needs into a cost effective solution. His work with us along with my direct knowledge of his work with another client has been exemplary. Already hired him for another project later this summer.

 

Bill Merriman

Owner at Stop N Go International

We've had a great working relationship with Corporate IT for some time now. After having had a few bad experiences with foreign 'help desk' individuals, we swore off using any person or entity that is not local and 100% trustworthy. I can unequivocally say that Paul and Jeremy know their stuff and are always on top of a solution to our IT problems that occur.  Whether it be hardware or software, they are always very responsive to our needs.

Mark the best of the best when it comes to an IT Consultant and product provider. We have worked with Mark since 2006 and have nothing but great results. He has helped our company with computers problems at all hours of the day and night and he not only is knowledgeable about his field, but also cares about his clients and their needs. I would highly recommend him and his company!

 

Dave Barber

Past Executive Director at United Way of Greater McHenry County

Let me begin by saying that it was a tough decision to select only three top attributes for Mark and his company. They qualify for many more than three. We switched to CorporateIT Department more than a year ago and nearly all of our IT problems have disappeared. Mark and his company have restructured our network and simplified our entire process. They have reduced our costs and increases our reliability. What a bonus! I couldn’t recommend anyone more than Mark!

 

Lisa Weber

Manager, Service Level Reporting at Sears Holdings Corporation

I’ve utilized Mark’s IT expertise both with our company’s computer systems and have had him service my home computer. Mark’s knowledge and ability to solve even the most complex IT issues are outstanding. He is quick to respond to requests for assistance and takes the time to find solutions. Mark is personable and has a great network of other business associates that I’ve been able to get referrals to when needed!

 

Jack Bechaud IS the social (net)worker!

Mark is great to work with. His knowledge and experience are superb and he does it all with a smile. Mark cares about his community and helping people. He remembers you and what you do so that he may be able to refer or connect you with the appropriate people, even when it’s not for his business.

I give Mark my highest recommendation.
