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.

Deer Park Diesel was originally opened in 2000 as Schuler's Auto & Truck Repair by Jake Schuler. After over 30 years of experience working in heavy equipment repair, Jake was laid off due to an injury in 1999. After recovering from his injury, he and his wife Terri decided to open a general automotive repair facility in their hometown of Deer Park, WA.

It's rare to find an honest and professional mechanic. I took my poor starting and low power running RV to Greg expecting to the worst. After diagnosing and cleaning my mass air flow sensor my RV runs like new. I was excited to learn the fix was simple but was still expecting to pay for several hours of labor which can be hundreds of dollars.

I have found a great group of guys to service/maintain my 2011 F350 DRW King Ranch. My first visit made me quickly realize I was with a group of Pros that know there way around a diesel pickup. They quickly diagnosed my coolant issue and ordered the parts required to get me back on the road. They have earned my business and respect.

These guys are probably some of the coolest most professional folks I've met in the business. From the East coast to the West. Guys there are definitely enthusiasts not just trying to burn your wallet. There automated update system allows you to take a look at what the mechanic working on your truck is doing (showing anything coming up in inspections or whatever there doing) Honestly one of the coolest things I've seen as far as giving the customer a peak and live update of what's going on. HIGHLY HIGHLY recommend anyone checking out these folks for any of your trucks needs. THANK YOU DEER PARK

Add a check engine light on my Dodge Which was code P 0 2 36 Which was the map sensor replaced it 4 times. And still had the same problem check it over there they put their scanner on it and ask a few questions And told me to replace it againIs through a different parts store I did and it worked great. The girlfriend also needed some work done on hers. Total what was wrong roughly what it would cost to fix everything which didn't seem unreasonable is trouble we are talking about diesel trucks. Everybody I doubt what there is nice courteous friendly helpful straight to the point no BS

If you're looking for an honest Diesel shop, look no further. I left a large sum of money in my truck. Yes I know, dumb. They secured it for me. Their service was exceptional, very knowledgeable. Check them out, you won't be disappointed.

I drove my RV to Deer Park Diesel for some preventative work. We live in Spokane but after contacting several shops to inquire about the work I wanted done and being put off for as much as a month, I reached out to Greg. I should have thought about their shop 1st! They completed the work in one day and my RV was finished on time. I trust their workmanship, they are professional and their prices are competitive. I will certainly drive again to Deer Park Diesel for any other work I need to have done to my RV. Great work Greg!!

I was excited to learn the fix was simple but was still expecting to pay for several hours of labor which can be hundreds of dollars. I was shocked when Greg said he had less than an hour of work into the job and said there would be no charge! THANK YOU!

I feel very fortunate to have found deer park diesel from the get go.
The place is well kept, the staff very helpful and friendly. The work done in my vehicle feels to notch.
They inform me of special needs for my rig that I would not have known of otherwise.
I highly recommend all diesel owners to give them a try.

Friendly staff! Competitive prices. I came in for an oil change and they were very clear. We always do an inspection. And they found several things that were in need of repair. They also took pictures of those issues. I love that they were able to show me what was wrong instead of just saying something was broken.
