Student Experience: David Guadiz, RT(R)

“I just really wanted a career change after working as an electrical engineer for 15 years and being stuck in a cubicle for 12 hours a day. I wanted a stable job with more flexible hours, something hands-on and with more interaction with people. 

“The best thing about the Radiologic Sciences program was the combination of both textbook and hands-on education. It really got me prepared for being a tech — in my graduating class, we all did well in clinicals and passed the registry.

“All of the students developed close relationships with each other and our faculty. The personal attention and pride that faculty members Christi Carter and Valerie Martin took in us was incredible; they really wanted us to succeed. 

“I use the skills I learned in this program every day on the job, as far as X-ray technology goes — although I did have to learn CT on the job. I would recommend this program to anyone looking for a career in the medical field — it’s a stable job that pays well, and the days go by really fast because you do such a variety of things. There are so many different career paths you can take in this field.” 

David Guadiz works weekdays at Lake Pointe Imaging Center in Rowlett and weekends at Baylor Medical Center-Frisco, doing CT scans of all parts of the body as well as X-ray and bone density tests.

An electrical engineer before changing careers, he had earned a bachelor’s degree in electrical engineering from Iowa State University before earning an associate degree in Radiologic Sciences in December 2005.

“I chose El Centro one, it was closer to home. It was a little more affordable than going to somewhere out of state or somewhere else. Just those two things were, were the main thing, the reason why I chose to go to El Centro. I think El Centro did an excellent job of preparing me for going into the workforce.”
