He holds special interest in colorectal cancer screening and hepatobiliary disorders, and received specialized training in Endoscopic Retrograde Cholangiopancreatography (ERCP), during his medical training.

Prior to joining MedStar Health, Dr. Parungao worked as a staff gastroenterologist at United Medical Center in Washington D.C. In addition to his clinical practice, he has devoted time to medical research in his field, publishing articles in numerous industry publications and presenting abstracts at several national conferences, with focus on the progression and continued advancement of care for patients with gastrointestinal diseases and disorders.
