A Few Satisfied Customers:

DeerPark Diesel did an outstanding job on my Ford Truck. They are reliable, skilled and get the work done to completion. I would recommend them to anyone for great service.

Clearly a family friendly business. I’ve never had such satisfactory service taking a vehicle to be worked on. Each step of the way additional time and parts was explained to me, the guys here even put on kids shows for my older kiddos that had to wait with me. We will definitely be returning for any other work we need done.

I'm a new customer and found the perfect place to work on my truck. I invested a lot in my truck and am very particular about who I trust to service it. The staff at Deer Park Diesel have been friendly as well as professional and straightforward on their products. Great service, wonderful people to do business with. 👏

Every interaction I've had at Deer Park Diesel has been a positive one! Easy to schedule appointments around my work, the digital vehicle inventory they provide is very detailed, and the guys at the front are friendly & helpful. I'm happy to bring my truck here from now on.

Outstanding, Friendly and Professional service. They dedicate time to explain in great understandable detail of any problem found. They instill confidence that their maintenance performance is quality and at a fair cost. QUALITY should be in their name. NO 5 stars, they deserve 10 stars.
