You will never see
us arriving
at a job sight
loaded with
5 gallon buckets
of rusty tools
attempting to
"wing it"

If we can’t diagnose your problem – it’s on us.


logosWe are a complete  heavy duty equipment and truck repair shop on wheels. We offer specialized services that can’t be found in any one shop – mobile or not.

As you navigate through our web site you will start to notice, when Mobile Diesel Medic comes out we realize if there is a breakdown most likely a lot of contractual obligations and livelihoods are being strained and the equipment has to get running quick but also repaired once and correctly. We get it. Trust me WE GET IT!!

Essentially if the book shows a three hour repair time you are charged three hours. Here is the kicker!! Flat rate shops reward the mechanics for beating book time. If a mechanic can stuff three hours of labor into one than the mechanic wins the lottery because he made three hours of wages in one hour. Hence in a flat rate shop there is an overwhelming amount of pressure to cut corners and speed up the repair. Almost all dealerships are flat rate shops. Mobile Diesel Medic’s business model does not base salary of mechanics on cutting corners. We are not a flat rate shop, but bill actual hours. That is why we can normally cut $1000 dollars off most diesel truck repairs vs. the dealerships.




Customer satisfaction #1

Customer satisfaction is our number one goal. We set the highest standards possible and we believe in honesty and integrity and in doing the job right – the first time around. We are the mechanic you can trust.


Mobile Diesel Medic

Mobile Diesel Medic is covering the entire San Francisco Bay Area, including: San Francisco, Santa Rosa, Richmond, Petaluma, San Rafael, San Leandro, Oakland, Alameda, Walnut Creek, Daly City, San Mateo as well as Sonoma, Contra Costa and San Mateo Counties.



Do not drive an unsafe truck, RV, Bus or piece of heavy machinery – We come to you!


At Mobile Diesel Medic we believe the speed and efficiency we can carry out a field repair is directly proportional to our sheer capital invested in inventory, tooling, education, software, and our diagnostic support services. We continually reinvest back into our company. Our business model is quite the opposite of the current trend. Instead of carrying less and less on our shelves, we are continually adding more and more. THE STRATEGY BEING, through the high quantity of quality parts we carry on our trucks we get your job done in half the time of a regular mobile repair service. Hopefully, from our capabilities to adapt to any adverse conditions your breakdown throws at us, combined with our stubborn tenacity not to just “band-aid” a repair, plus our arsenal of software, tooling, inventory and of course our highly educated technicians, we will hopefully win you over as a new customer.

**Heads up!! I realize the above paragraph can easily be cut and pasted onto any Mobile Repair Service website. I imagine MDM’s talk will be cut and pasted on our competitors web sites soon enough. But our walk will never be copied. How do you, the customer, know we are the real deal and not just digital manicured web fluff? When you start exploring our website please take a close look at our photos. The background on most of them will be the same white plastic covered work table smudged with grease. One of my employees, for a month straight, was paid to pull all our equipment, our fastener bins, our repair kits, our inventory, all of it piece by piece as my wife painstakingly photographed each item on the same white plastic covered workbench. Mobile Diesel Medic’s arsenal of equipment and inventory we claim to carry exists in our building and in our trucks. It is not quickly ordered via a third party after we collect your credit card #. I couldn’t be more proud to say “we are old school around here.”

We service all domestic and international brands including:

 International | CAT | Cummins | Detroit Diesel | Hino | Freightliner | Ford | Mitsubishi Motors | Kenworth | Isuzu Trucks | Peterbilt | GMC Truck | UD Trucks
