Devil Mountain Diesel - About Us

Devil Mountain Diesel was founded by owners, Mark Fuenzalida and Jason Loeliger.

Mark and Jason both grew up in the bay area and have been in the automotive industry as long as they can remember. They both have decades of factory training experience to provide first hand knowledge to both their employees and their customers. Mark and Jason have built the shop from a “two man show” into what it is today with several technicians and an office manager to complete the team.

Not only can Devil Mountain Diesel keep your truck on the road but we can aid in styling or upgrading your vehicle to your liking as we offer lift kit services, wheels & tires, vehicle wraps, window tinting and more! With close access to many major freeways, Devil Mountain has a perfect location for those located all over Northern CA and the entire Bay Area

If you can see Mount Diablo from where you are, then you should be taking your diesel truck to Devil Mountain Diesel!
