Dok Klaus: A German-American Success Story

Dok Klaus Computer Care recently celebrated its 20th year Anniversary!, and after winning 11 consecutive awards for Best of Warrenton for Computer Repairs and Service, is now recognized as Best of Fauquier.  “Dok Klaus,” a West Berliner with years of international telecommunications, programming, and computer experience, immigrated to Warrenton with his German-American family in 2001. Always helpful with repairs and advice, he soon became known to friends and neighbors as the “PC Dok,” which led to the founding of his own business.

From modest beginnings in July 2002, Klaus Fuechsel morphed from a lone computer guy to the familiar face of Dok Klaus Computer Care, originally in Old Town and now in its own spacious grounds on Waterloo Street, Warrenton. Dok and his team of technicians are known throughout the suburban/rural Piedmont region for personalized computer care, network engineering, web development, and custom solutions for businesses and homeowners. The company’s approach differs from national franchises and outsourced technical support by doing things the “Dok Klaus Way.”

Klaus emphasizes talking the “language of the client.” Building trust and loyalty through face-to-face consultations, Dok provides consumer education and creative problem solving. He makes house calls to business and private homes, and provides remote support, too. All of this is delivered with good-natured German humor and a personal commitment to quality.  And Dok believes in educating his clients; check out some of his published articles at!

Dok’s team mascot: the Klausi-Mausi. This copyrighted creation came to life over a decade ago as a mnemonic for the German pronunciation of Klaus. First hand-drawn by Melanie Fuechsel, one of Dok’s daughters, it was perfected and digitized by Cindy Raggo. Together with Cindy’s “Usual Suspects” the Klausi-Mausi appears regularly in Dok Klaus Computer Care advertisements, comic strips, calendars, and swag.
