Dallas College

Student Experience: David McNabb

“I’ve been an Automotive Technology instructor with Dallas College for seven years, and there are times we run into welding needs specific to automobiles. I wanted to have that skill set, so I came here with the idea of taking one basic welding course, but now I want to take more. 

“The quality of instruction is excellent, and Dewayne Roy is a very knowledgeable instructor. One thing I really like about the class is the teaching demos; every morning I’ve walked into the lab, Dewayne is set up and ready to go with another demo. 

“Dewayne has a huge tolerance for the learning curve — he’s very elastic when it comes to interaction with students. He may have to repeat the same thing several times a day or week, and he does it patiently every time.

“After taking one welding class, I'm not an expert, but I do have a great foundation. I’m confident that I could do a good-quality weld in most situations I’m likely to run into.” 

David McNabb earned an associate degree in Automotive Technology and a Bachelor of Business Administration degree from Texas Tech University. Before becoming an Automotive Technology instructor, he worked in several GM dealerships and as a field service engineer for GM.

“I was eager to learn, and the Diesel program really excited me. The more I learned, the more I realize it’s not so hard. All of my instructors have been knowledgeable; any questions I had for them, they were pretty much able to answer everything. These are great courses if you want to work on diesel engines.”

“It’s great to have intelligent capabilities, but if you don’t have the skillsets to back them up, what’s the point of going out into the real world? If you have a practical skill, you can always put bread on the table.”

“People look at a car and open the hood and see all the hoses and connections, and maybe think, ‘I am never going to figure this out.' Then you learn the basic concepts, and it’s more simplistic than you would think.”

“The students here are also attentive and helpful — I found out right away that there’s a group of them who have been here a while and who will chip in to help you do anything you don’t understand or help hold something you’re working on. I think that attitude is a reflection of the teaching here as well.”
