German Motors Inc. Professional Staff

Mark R. Yoakum


Mark graduated from Denver Automotive and Diesel College in 1977. He then started his career at a major Mercedes-Benz dealer in Denver where he became a Mercedes-Benz Master Technician and received the Star Technician Award in 1985. He advanced from Mercedes-Benz line technician to shop foreman and then to service manager for the entire multi-line dealership, all in 10-years. Having met his professional and personal goals at the dealer level, he set out to achieve his highest aspiration -- to own and operate his own Mercedes-Benz repair facility. In 1987 Mark began his employment at German Motors. Three years later he took control of the business. Using his extensive Mercedes-Benz dealership knowledge and experience, he transformed German Motors into a modern service and repair facility specializing solely in Mercedes-Benz. He acquired all the latest and most advanced Mercedes-Benz-approved diagnostic equipment, built a comprehensive data library, and hired and trained service technicians to his exacting professional standards. Under his direction, the shop has become known for its technical expertise and customer service.
