On 10/25/2024 Ashton Podlin had this to say:
Diamond diesel is one of my favorite places to go. They always do amazing work. I will never go to a different company!

On 10/14/2024 Jeff M. had this to say:
Busy, busy, busy little shop which provides PHENOMENAL service at a respectable price point..... Limped a F-350 DRW Diesel in with a brake issue MULTIPLE other shops tried fixing..... Took DIAMOND DIESEL all of five minutes to FINALLY find the problem and determine what needed to be repaired/replaced. (Getting two new parts in is taking a LONG time....). Thankfully as the other shops just guessed and replaced parts with abandon I will have an entire new brake system when the two new lines are installed WHICH also allowed me to get DIAMOND to spend some time getting my dual ly ready for this winter... Phenomenal work.... Great prices.... Fixed right the first time is WHY you have to wait for an appointment and well worth every second...

Zach got my truck in for maintenance really quick. He got the alignment perfect and balanced the wheels which gave me a much smoother ride. Super nice to deal with.
