5 Gas Analysis class was one of the best I've ever taken, I highly recommended it for anyone wanting to improve their diagnostic skills.

A great class like always, I've been coming to as many as I can for the last few years. Wally is an outstanding teacher. I am looking towards many more classes down the road. Thanks again.

It was very good information, completely top notch and relative to repairing most modern vehicles. - Chris K (5 star review found on Facebook)

Really enjoyed learning from their instructor named Wally in Raleigh NC. Took the two night 6.7 diesel class. - Nathan J (5 star review found on Facebook)

Absolutely the best source for local training. The books you receive from class are priceless. My goal is to own every book and take every class available to me from this point on. (I just took the 6.7 class last week and I don’t even work on diesels) The office staff is amazing as well. Go above and beyond to help get you the info you need. - Jason M (5 star review found on Facebook)
