I'm from out of state and Andrew his team took amazing care of me. Got me back on the road and taken care of at a great price. I wish I could use him as my full-time mechanic. If you are local, I wouldn't let anyone else touch your truck.

Unbelievably GREAT! Wish there were six stars. I called 7 other marine diesel services and only Andrew Welsh could step up and deliver. Forget Greg Poole and the big shops! Thanks Andrew!

Had a Heater Core hose bust on us in the middle of a project we started early this morning and barely made it to Welsh Diesel before it was necessary to tow. Thankfully Andrew and the crew jumped right onto repairing the truck as the local O’Riley’s had the part in stock. I’m grateful to have such a professional and capable facility so close to home as they have always made us feel like a priority. Nothing but great things to say about Welsh Diesel and the family here to support us. What a blessing, truly!!!!

"This diesel shop is beyond great. Excellent service and great workers! Andrew is always friendly and very knowledgeable. I've had some minor issues with my vehicle and he was quick to help me out saving me money and time. I recommend him and his team very highly. I've had shops take me for a ride in the past but this shop is honest and professional in all they do!"

"They guys at Welsh are amazing. They were helping me diagnose my truck over the phone before i even brought the truck in. After i was in over my head they fixed it right up. Did their own diagnosis gave me my options and got me squared away within a week. These guys will have my business for any diesel issues i come across."

"My mother in law was in town and her check engine light came and her Audi was having issues starting. We were referred here from someone very reputable so we went. Andrew went well above and beyond to work on her car, scan codes even kept it overnight and made sure everything was OK with her car as she lives 7 hours from here. I can't thank you enough for helping her in time of need and you have gained my service as well. Thanks"

"Wife and I were coming to town, we were in need of some work while truck was down. We made one call only and Andrew responded. He was understanding willing and solved our issue. It's rare on the road you find anyone that isn't just out to bleed you dry at any opportunity. You can tell that is not what they are about!! Fully recommend this shop."
