I went there for a repair, I was well looked after. I would recommend this place to anyone. Great people.

If your truck is broken down, you can get a ride to the hotel. Big break area and plenty of options for delivery.

— Lewis O.

Fast friendly service and a company that realizes trucks don't stop at 5pm.

I can not express enough, how thankful I am that the team at TLG - Great Lakes, conducts business the way that they do. They have become my regular shop for maintenance (scheduled or not!). They are fast and efficient. I also never feel taken advantage of when I look at the labor portion of the bill and the quality of work is above and beyond any other shop I have had experience with. Many thanks to the entire team

Awesome people and great customer service.
