The absolute highest level of accomplishment for a Toyota Technician is Master Diagnostic Technician (MDT). Think of the MDT as the "Professor" of the vehicle service and repair world. These are the guys who can find the problem and fix it when no one else can.Ā  They are the true geniuses of modern auto repair.

At Bob Johnson Toyota we have four Toyota Master Diagnostic Technicians (MDTs).

To put this in perspective, if a Toyota dealership has one Master Diagnostic Technician, it is big news.

At Bob Johnson Toyota, we have four!
