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.

“You should never stop learning in today’s world. If you do, you get left behind like the dinosaurs. Once you have knowledge, though, no one can take it away from you. The most important thing I learned is how to have the tools you need in today’s workforce.”
