tkg-logo-large-1Specialized training for technicians and enthusiasts who have a desire to learn more about European vehicles and engines

The Knowledge Gruppe LLC offers specialized training for technicians and enthusiasts who have a desire to learn more about European vehicles, and engines. Classes are based from both online and classroom environments. Online classes provide initial information to enrollees, and provide the necessary groundwork for the enrollee to progress to the classroom & Lab environments, where hands on instruction is carried out. This unique method of progressing through the learning experience helps build confidence, while providing a more evenly trained group of hands- on class attendees. Progressive training in this manner ensures that hands- on classes flow well, increasing the amount of content the attendee can absorb during the class. Some enrollees will choose to only attend the online classes, while others will wish to carry out the procedures in the hands- on comfort of our Advanced Training Facility. The Knowledge Gruppe LLC is comprised of a group of instructors that have extensive experience in their field, and are often experts, inventors, and developers. These instructors all share the common trait of “learning things the hard way” through years of hands- on experience in their field of specialty. These instructors are not just trainers, each spends the majority of their time researching and developing problems in their own shops, and once every few weeks they take the time to share these as instructors for Knowledge Gruppe LLC classes. Put simply, our instructors are real shop owners and technicians/ mechanics that get dirty on a daily basis, and then instruct others the smarter, easier way of getting the job done. IMG_0117_1024
