Guaranteed Computer Technology (GCT) was originally incorporated as Mobile Office Machines in 1967 by Will & Mary Volmert. In spite of the criticism, they established themselves as a service only organization focusing on office equipment maintenance including typewriters, word processors, and calculators. From the very beginning the critics contended that the business strategy was not viable because of the lack of a product oriented selling effort. Time has and always will prove a business strategy, and ours has held its own.

30+ years later our business strategy has proven itself and "Service" is a buzz word organizations utilize to support their selling effort. At GCT service is not an “extra” to be tacked onto a sale. It is a core business function. We maintain a 5/1 service personal to sales/administrative staff ratio. This means that 15 or our 18 employees are direct service producers. This focus and ratio improve our efficiency in providing our clients exactly what they expect, excellent service.

Our dedicated service professionals are located throughout our service area and are ready and available to meet your various service needs.
