"School is not my forte. I learn by doing, not reading. Although I did consider other colleges, TSTC stood out because of its hands-on learning. Because of TSTC, I now have the dream of opening up my own diesel mechanics shop. With what I learned at TSTC and the experience I’m gaining at Ag-Pro, I know that it can become a reality.”
