Student Experience: Jacqueline W. Cooksey, RRT, RDCS

“I had a great experience at El Centro when I earned my associate degree in Respiratory Care, which is why I went back when I decided to earn a certificate in Cardiac Sonography. It’s such an excellent school with an excellent reputation. Any time you mention it to people in the medical profession in Dallas, they know that you have gotten a good, solid education and that you can do the job they hire you to do. 

“I was a respiratory therapist at St. Paul Hospital on the heart transplant team. I became so fascinated with the heart that I wanted to find out more. The doctors I was working with suggested I go down to the cardiology department and really see if I was interested — and I just loved it. 

“I love echocardiology because every heart is different. I love interacting with the patients. Cardiac patients are usually nervous, and I try to put them at ease. I can always find something to get their mind off of what I’m doing. This field is also great because I get to see the outcome — what happens to the patients. Most of the time, if they do what the doctors say with their diet and exercise, things can really turn around. 

“At El Centro, I learned to always put myself in my patients’ positions. Nothing is guaranteed, and anything can change in a heartbeat. You treat every patient on the table like they were a family member or your best friend. Everything that Cathy Carolan said is true: If you go over and above what you need to do, your work will speak for you. You always aim for 100%. You may fall short, but you’re still going to produce good-quality work.”

“My training and education at El Centro provided me with the knowledge and skills required to perform my job very well as an invasive cardiovascular specialist. The best part of my job is the satisfaction I gain at the end of each day, due to the fact that I’ve made a difference in my patients’ and their families’ lives by being a part of the lifesaving medical team.”

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.”
