Izaac Mireles always knew he wanted to make money, live comfortably and enjoy his hobbies without worrying about anything else outside of his work. A set future career was not always on his mind as a kid, but he knew that he was interested in following his father’s path in the oil field. His original plan was to go to work for six months out of the year and make a ton of money to buy his parents whatever they wanted and live a luxurious life! When he realized living far from home to work in the oil field would keep him from his family, missing family events, holidays and other important milestones in his loved ones’ lives, he decided to pivot.
“Knowing that I would be gone for all that made me realize that the money would be wonderful to have and make everything more fun, but being with family and friends [while] enjoying the people I have around me was worth more than the money could ever be,” Izaac said.
During high school, he took three levels of automotive technology off-campus from Birdville High School.
“What I loved about this course was all the friends, memories and connections that were made, and the opportunities that were earned and given to help myself along with other students to have more success in that career and in life,” Izaac said.
While taking these courses, his teacher introduced him to an internship with RDO Equipment Co., and he decided to apply. With no work experience before applying, this internship set him up for success and taught him a lot about working in the field. After graduation, he accepted a job with the company and has been there ever since.
“I would have to say that working in this career keeps you on your toes,” Izaac said. “There’s always a machine or truck that is going to come in and really make you think, and with that, the feeling it gives you when you finish a job, that feeling of accomplishment to me is much greater working on these pieces of equipment compared to a normal car.”
