Melissa Metzger, RT(R)(ARRT)

“As a radiologic technologist, the patient always comes first. As an instructor, the student always comes first. I believe it is very important to train future professionals in the importance of ethical patient care and health care delivery.

“After hours and hours of clinical work in the hospitals, the Radiologic Sciences program taught me how to be familiar with taking so many different types of X-rays and sometimes having to think outside the box. I still work for Children’s Medical Center and have had nine years of experience here. 

“All students coming out of this program will be able to position each patient for every type of X-ray, no matter the difficulty of the exam. Some patients may be super tough to hold still or to calm down. You have to use special techniques to help them. Always try to put yourself in each patient’s shoes. They are probably having a harder day than you are.

“I love patient care. Each patient is so different and I love being able to take care of each of them.”  Melissa Metzger earned an associate degree in Radiologic Sciences in May 2007 and started her job at Children’s Medical Center immediately after graduating. She began teaching full-time in the Radiologic Sciences program in the fall of 2016.

Medical Laboratory Technician Methodist Medical Center of Dallas
“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.”
