About Matthew J. Oman, MD

“When I entered medical school, many of my classmates knew the specialty they wanted to work in; however, I had an open mind and was excited to be exposed to the various specialties of medicine. When the time came to decide, I had noticed that I was most interested and happy when encountering patients with gastroenterology and hepatology health issues. While I am fascinated with the pathophysiology and medical side of this specialty, it was the technical, hands-on, endoscopic aspect that solidified my decision. I was amazed as a medical student the first time I saw a bleeding gastric ulcer treated endoscopically. While training in fellowship, I could see how endoscopy is much more and can relieve a variety of issues and symptoms for patients, from removing a gallstone lodged in the bile duct, opening a stricture in the esophagus so a patient can swallow again or draining a cyst through endoscopic ultrasound.

“I was taught by a mentor that one of the main goals for a physician is to relieve suffering. Now, in many situations we get to see patients when they wake up from a procedure and their pain or symptom has resolved. It is a privilege to take care of patients and be a part of this challenging and incredible specialty.”
