They work well coordinating with the insurance company and give a guarantee to their work. Thanks Andrew for all help! (He even helped me move my car seats from one vehicle to another)

After a minor incident, our Cadillac Escalade needed an alignment. We took it to a body shop first. When we picked it up, it was driving terribly and felt almost uncontrollable. They realigned it, same issue.

Next stop was Cadillac. We explained everything to the service manager, they aligned it again and told us it was back in spec. I picked it up… and it still drove awful.

I bumped into Michael Sullivan and we talked about what was going on. So we brought it to Sullivan’s Truck, Auto & Collision Repair.

From start to finish, the experience was completely different. Great customer service. Clear communication. They test drove the vehicle themselves and confirmed what we were feeling. When we picked it up, they walked through the alignment printout with us in detail — something no one else had done.

The Escalade now drives exactly like it should. They even had it cleaned and ready to go.

Can’t say enough good things about the team at Sullivan’s. Professional, honest, and they actually fix the problem. Highly recommend.
Response from the owner:Hey Jacob --This means a lot to us and our team, thank you for your kind words! We know how frustrating it is to be told everything is “fine” when your vehicle clearly doesn’t feel fine. We’re so happy we could test drive it to feel what you were feeling and walk you through everything, so you felt confident getting back on the road safely. If you ever need anything at all, we’re here for ya!

Unfortunately, I was in an accident and my car was towed to Sullivan’s. I’ve lived in Kingwood for over fifteen years and have driven past their shop hundreds of times. It always looked busy, and I remember thinking, they must be doing something right.

From the moment I walked into the lobby, I was greeted with genuine smiles. The person I had the pleasure of working with was Pat. He was respectful of my time, listened carefully to my questions and concerns, and went the extra mile to make sure everything was handled correctly.

Even though my car was totaled, Pat was a perfect example of excellence and professionalism. If you ever need to take your vehicle to Sullivan’s Auto Body Shop, you’ll be in great hands with Pat and the rest of the team.

Wow! Had some minor work I needed done so I went to Sullivan's.. I had gotten a part online so I wasn't sure of my reception... William Scott could not have been more accommodating and helpful and than didn't even charge for the work done!! Will definitely return for maintenance and repairs on my two vehicles in the future!!
