“I became interested in the Medical Laboratory Technology program because I had always enjoyed the laboratory components of my science classes, and I wanted a career in the medical field.  “Once I was accepted into the program, I found the instructors to be personable and knowledgeable, and they made me feel well prepared for my clinical rotations. Lisa Lock and Denise Griffin always make sure that everyone understands the material and really want their students to succeed. 

“I believe that my education from El Centro will enable me to easily find employment in a laboratory when I finish the program. There are so many areas and options in the laboratory field, and I personally hope to work in microbiology. 

“I have applied to the distance learning program at the University of Texas Medical Branch to earn a Bachelor of Science degree in clinical laboratory sciences. I feel confident that the Medical Laboratory Technology program at El Centro prepared me for higher education in the laboratory sciences.” 

Loni McElhinney received her associate degree in Medical Laboratory Technology in June 2008 from El Centro and was named the program’s 2008 Outstanding Student. Immediately after graduation, she was hired as an MLT by the blood bank at Medical Center of Plano, where she types patients’ blood and tests it for antibodies to ensure that they don’t have a negative transfusion reaction when receiving donor blood.

“My first experience at community college was taking ESL classes at Richland and Brookhaven, which were close to where I lived. Then when I started exploring what kind of program I wanted to take for a career change, I saw Medical Laboratory Technology and transferred to El Centro ... I always tell people who are thinking about community college to think about Medical Laboratory Technology, and I tell them about my personal experience with the program. It’s a stable job, in a quiet environment with a lot less stress than many other medically related fields, and the people are very friendly and professional. I really love my job.”
