"You become a mentor, an advocate and role model to the students," Gregory said. "The job of an instructor is never done."

Hometown: West Memphis

Age: 21

Where I Trained: Arkansas State University-Mid-South

What I Earned: Associate degree in Applied Science–General Technology

Job Title: Diesel Technology Instructor

Employer: ASU-Mid-South

Gregory grew up around cars and trucks, so it felt natural to pursue a career in the transportation industry. And Gregory always knew he wanted to make a difference in the world. 

His late grandfather encouraged him, saying, “If you want to make a difference, be the difference.” Teaching runs in his family, so Gregory decided to become an instructor. 

During high school, Gregory did dual enrollment. This allowed him to complete college classes while getting his high school diploma, and he found this route to be quick and affordable. After earning his associate degree at ASU-Mid-South, Gregory accepted a position at the school as a diesel technology instructor. Now, he teaches the next generation of diesel technicians and makes an impact on their lives—as his teachers did for him.

Gregory teaches high school and adult students how to work on vehicles, use shop equipment safely and to work alone or on a team.

“You are not just an instructor,” Gregory said. “ become a mentor, an advocate and a role model to the students. I have to make sure each and every one of my students develop employability skills...," Gregory said. “[They are prepared] to enter the workforce immediately after they finish the program and excel in their profession.”
