certifications on:

Adrian moved into the valley in 1992 to attend UTI (Universal Technical Institute) in Phoenix, AZ​.  After finishing school, Adrian worked for many of the valley's dealerships, like CAT, Cummins, Peterbilt, Freightliner, and Kenworth; where he received a tremendous amount of training which came with certifications on electrical, fuel, and the newest emissions systems.

With over 20 years of experience, Adrian decided to start his own business to be able to provide dealership quality work, at a price that would be affordable for smaller fleets, and owner operators. 
Adrian's main goals are to help his community by creating jobs, and to offer many benefits to his employees, like health, and life insurance, paid leave, vacation time, and scholarships for them and their families.
