Inspired by mother’s heart journey to study Sonography

For Vanessa Colunga, higher education represents more than a personal milestone, it is a promise to her family and a pathway to healing others. The 18-year-old Donna High School graduate is beginning her journey at South Texas College (STC) with plans to enter its highly-competitive Diagnostic Medical Sonography program and specialize in cardiac imaging. 

As the first of five siblings and the first child to an immigrant mother, to pursue an associate degree, Colunga is determined to turn her inspiration into impact, combining academic excellence with heartfelt commitment to patient care. 

“I chose STC as my college of choice because of their vast options of medical programs, as well as their many student support aids,” she said.  

Admission into the course required taking the Health Education Systems Incorporated (HESI) exam and submitting scores within a strict timeframe. 

“I was lucky enough to get the last class section available out of four,” she said. “It was competitive since a lot of other students who want to enter this program also applied.” 

Her drive to pursue cardiac sonography is deeply personal.  

“My mother inspired me to pursue sonography,” she said. “She has heart failure and because of that I want to pursue cardiac sonography in order to find early signs of heart disease in others, that could then help them take the next steps into improving their health.” 

A defining moment reaffirmed her calling during a routine heart checkup of her own. 

“The sonographer that was examining my heart made an experience that's usually unnerving and uncomfortable, one that was free of these negative emotions and atmospheres,” she said. “This experience made me realize I chose the right career because that was the exact impact I want to have on the people I encounter.” 

 Earning competitive grades has been one of the most demanding aspects of preparing for the program. While a minimum grade above a C is required, Colunga understands that earing straight A’s places applicants at the top of the selection list.  

“So far I’ve achieved those requirements, but it can take a toll with the studying and time that is needed,” she said. 

The academic rigor has transformed her personally. Once accustomed to completing tasks at the last minute, she has developed stronger time management and organizational skills. Much of her week is dedicated to studying for quizzes and exams, often sacrificing social activities to stay focused on her long-term goals.  

“One of the biggest and most noticeable sacrifices I’ve made in order to stay committed has been using my time wisely,” she said. “I always try to put my studies first.” 

Throughout her journey, her family has remained her greatest support system. 

My siblings have helped me numerous times to study for exams through flash cards and fact checks,” she said. “My mother has been there for me when I feel discouraged about certain topics I have trouble understanding. My family has without fail cheered me on for every good grade I have earned.” 

Colunga believes sonography plays a vital role in health care, particularly in monitoring new life and detecting health concerns early. 

“It has allowed us to view health of every new generation,” she said. “Being able to see development through sonography helps not only the medical staff, but the family, and to limit surprises that may come.” 

Colunga plans to continue her education even after completing her associate degree. After learning that STC offers bachelor’s degree options, she hopes to eventually return to pursue a Bachelor of Applied Science in Medical and Health Service Management. 

“The impact I hope to have on those I serve would be one that changes the usual setting that sonography appointments are put under -uncomfortable and nerve-wracking,” she said. “I hope to bring my patients peace, reassurance and validation.” 

Her advice to future students considering the Sonography program or any academic path is rooted in perseverance. 

“Never let yourself get discouraged enough to quit,” she said. “Keep going forward, work and study hard, see everything as an opportunity to grow and everything you do will be worth it.” 

For Colunga, her journey towards cardiac sonography is fueled by family, resilience and a passion to make patients feel safe and supported one scan at a time.
