Q&A With Dr. Dominguez

Question: Why Did You Get Into Healthcare?

Dr. Dominguez: I realized I had a calling to help those who are sick. When I was young, my grandfather started feeling sick and was later diagnosed with gastric cancer. I was eager to help him in any way I could. I would accompany him to his doctor’s appointments so I could explain to my family what the doctors had said. When he finally passed away, I knew I wanted to become a doctor so I could take care of people like my grandfather and make an impact in their life and their family.

Question: What Drew You To Gastroenterology?

Dr. Dominguez: During my third year of medical school, I had the opportunity to rotate through a 2-week gastroenterology elective. One day I went to the ER to see a patient who was having GI bleeding. The patient needed an emergent upper endoscopy where we found him to have a bleeding stomach ulcer. I was amazed at how the GI attending handled scope and how quickly he “put out the fire” as he swiftly stopped the bleeding stomach ulcer to save the man’s life. From that moment on, I knew I wanted to become a gastroenterologist.
