  • Praise from our clients

    "As small business owners working from our home and leveraging the Internet, PC performance is of the utmost in criticality! Having GBS available for repairs at a very competitive price, and sometimes the option for on-site (or at home) service, makes it highly desirable to do business with them! They are very knowledgeable and have a great rapport with clients because they can describe in "lay terms" what needs to be done. They'll help with every step along the way, depending on what you need. We highly recommend GBS for any issues you may have!"

    "As Brian completes his final tasks on the Kraft C.A.R.E. Project, I would like you to know that Brian did an excellent Job on this project. He handled all tasks completely and professionally."

    "Just wanted to thank you for not only recommending that we virtualize all the equipment in the server room but also for doing an excellent job on this project. We know this project had a lot of hurdles to overcome but the results have been fantastic. Not only are our applications running smoother, but we have also realized a reduction in our electric bill due to fewer pieces of equipment running and the cost to cool down the room from that equipment. In addition to everything else, our server room is neat and organized. We recommend GBS to everyone for their networking needs."
