“Doctors Need Heroes too.” Meet our Medical Assistant Instructor, Liliana Pettis.

Before Liliana was an SCI medical assistant instructor, or MA, she was a young mama and an SCI student herself. Here she tells her story.*

You see, I have been in many of my students’ place. I was blessed to have my family and friends to help me with my son and encourage me to go to school as a medical assistant where I could “do something meaningful” with my life. I remember walking into the school building at SCI and signing up for the medical assistant program knowing that I had made a decision that would change my life.

What I could not have known about then were all the lives of others that I would later impact as a medical assistant instructor at Southern Careers Institute. When I walked through those doors 15 years ago, I did not know that I would be leading, teaching, and showing others what I was once taught. It didn’t cross my mind as I trained on-the-job that I would soon be training future medical assistants in the local and surrounding areas of Corpus Christi.

It is a rewarding job to help place, inspire, motivate, and work with those that will soon be doing what I have done. When I see a smile spread across my students’ faces as I share some of my most memorable stories in the field, that’s exciting to me. I enjoy giving them something to look forward to, knowing that they too will feel as rewarded as I was in a career that makes a difference as medical assistants.

What I also could not have anticipated, was working alongside someone else who also is a medical assistant instructor and SCI graduate, my coworker, Guadalupe Hernandez. She finished school in 2005 and now years later, she, too, is preparing, leading, and teaching others to be wonderful medical personnel within our community. When I am asked “Why be a Medical Assistant?” I simply respond with “Because doctors need heroes too.” To be a part of molding, shaping and creating a diamond-in-the-rough is beyond pleasing. To have a student return from externship with a “thank you” only reminds me that I am helping–one smile at a time.


Lilana–far right in the navy–celebrates with her students.

Liliana is a graduate from Southern Careers Institute where she received certification 15 years ago. After graduation, Liliana launched her career working for Almouie Pediatrics and later became a member of Driscoll Children’s Hospital where she was a prominent part of the Craniofacial and Reconstructive Team under Dr. Kevin Hopkins for over 7 years. Liliana is now a full-time medical assistant instructor at SCI Corpus Christi.

What SCI Students Are Saying

“I made a complete career change when I started my training at Southern Careers Institute. I needed a stable career to continue providing for my growing family. SCI provided me with the medical terminology and know how that I needed to understand and acquire a career in the medical field. SCI taught me that it doesn’t matter where you are in life right now; you always have room to advance and learn.”


Denise S.
Medical Assistant

“I am extremely grateful for the assistance I received from SCI’s Career Services team. I enjoy where I work and what I do. SCI has helped me succeed in life by getting me the necessary education and by making me a stronger and more confident person.”


Raquel S.

“Once I graduated from SCI, I had a sense of accomplishment that helped me through the job search process. SCI provided me with the opportunity to brush up on my skills, extend my accounting knowledge, and they boosted my self-confidence. I went to work two days after my last day of school.”


Annette D.
Business Accounting

“When my youngest child graduated from high school, I told my husband that it was my time. I went back to school to change careers after spending 37 years in the business field. At SCI, the instructors are professional, and they care about what they are teaching you, as well as expect you to give 100% in return. I had problems understanding how to draw in syringes and give injections. I requested extra help from a knowledgeable instructor, and I was able to receive one-on-one training. Today, I draw injections for approximately 100 patients each week. I am very confident in what I’ve learned. SCI has given me the chance to do what I always wanted to do. Thank you for my education. I am doing wonderful.”


Bonnie M

“I am now a certified Lab Tech. SCI helped me get an externship, and I came out with a job. After my little sister had cancer, I knew I wanted a career in the medical field that allowed me to help others. I am happy about what I do.”

Olga C.

“Southern Careers Institute totally surpassed my expectations. Once I finished school, the Career Services team helped me find a job. I would tell anyone thinking about starting career training that you have nothing to lose and a lot to gain. I wish I would have started my training sooner.”


Valerie D.

“I am very happy with where I am and where I’m going. Through high school, I struggled with math. When I came to SCI, I enrolled in the Business Accounting Specialist program to see if I could do it. SCI provided me with the accounting skills I needed to help me find a career. Now, I have an amazing career and room to grow in the company.”
