Student Experience: Jewelressa Dunbar, B.A.A.S., MA

“I took a couple of classes at Mountain View and became interested in doing something in a medical field. My advisor there pointed me to the allied health professions at El Centro, and I went there to interview for the Medical Assisting program. 

“The best part of my education was my professors — I’d like to particularly thank adjunct faculty member Diana Drury. 

“I use everything I learned in my education on a daily basis. I like helping people and feeling that I’m an asset to the community. When you work in the health field, you always have a job, and you can really make a difference. Every position may not be for everyone — but it’s a good, flexible field where you can move into the areas that you like the best, whether it’s the front or back of the office, or working with patients. 

“The most important thing I learned is to be open to learning new things. There’s no one right way to do everything.” 

Jewelressa Dunbar earned her Medical Assisting certificate from El Centro and also earned a Bachelor of Arts and Sciences degree from the University of North Texas. In her current position, she has worked both in the front office, in reception and filing, and in the back office, handling medical records and processing patient checkout and insurance payments. She also conducts hands-on procedures such as giving injections, checking vital signs, prepping patients for tests such as EKGs and authorizing tests and medications. First asked to work with one physician, she has worked in all areas across the facility for a total of 30 doctors. Her current duties primarily include taking vital signs, giving injections, scheduling tests, calling in medications, triaging calls and performing any other common procedures done in the office.

“I think I'd recommend El Centro to anybody, and I always do. If someone wants to go into respiratory or wants to learn more about respiratory, I point them in that direction.”

Respiratory Care Practitioner Baylor University Medical Center
“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.”

“There’s not a thing I don’t use from the information I learned in the Medical Front Office program. The classes did a very good job of teaching skills that we’d really need. We were always learning from people who have worked in the field, not just learned information in a classroom.”
