Brent Hiramoto

Dr. Brent Hiramoto is a gastroenterologist specializing in the treatment of esophageal reflux and motility disorders, eosinophilic esophagitis, anorectal disorders such as fecal incontinence and chronic constipation, and other diverse disorders of gastrointestinal motility and gut-brain interaction. His clinical research interests focus on obesity epidemiology and the effect of obesity on the spectrum of foregut and hindgut motility disorders. He has published in several peer-reviewed journals including Gastroenterology, Clinical Gastroenterology and Hepatology, The American Journal of Gastroenterology, and Alimentary Pharmacology & Therapeutics.

He is a graduate of Northwestern University Feinberg School of Medicine where he obtained his MD. He then completed his residency training at the University of Southern California/Los Angeles General Medical Center. After residency he pursued his fellowship training in gastroenterology as a National Institute of Health (NIH) T32 fellow at the Brigham and Women’s Hospital, a teaching hospital of Harvard Medical School. He completed his MPH at the Harvard T.H. Chan School of Public Health during his fellowship training. He is excited to return to Los Angeles where he plans to pursue his interests in research, teaching, and patient-centered care.
