JM Auto Service started in June of 1993. The owner, Jefferson Miller, has many diplomas and recognition letters for his quality work.

Prior to this, he started out in the automotive business in 1986 as a body shop manager, then later moved on to become a service/parts manager for a motorcycle dealership.  Shortly after, Jefferson gained quality knowledge as a service manager at a large repair shop where he was taught how to do exceptional car repair.  Jefferson later began his own business, called JM  Auto Service. 

JM Auto Service offers  complete car care and is ASE Certified.  From inspections (cars and motorcycles), to alignments, painting, shocks, struts, brakes, and engine rebuilding.  We do it all. 

We are a  full service body shop ready to handle any type of collision repairs. Customizing hot rods, street rods, bikes, and even guitars. We also restore antiques, classics, and muscle cars.
