Dr. Omar Viramontes is a compassionate and highly trained physician specializing in
Gastroenterology, Hepatology, and Internal Medicine. He completed his undergraduate
studies at the University of California, San Diego (UCSD), earning a Bachelor of
Science in Human Biology. He went on to receive his medical degree from the David

Dr. Viramontes completed his Internal Medicine residency at the University of California,
San Francisco (UCSF), and his fellowship in Gastroenterology & Hepatology at UC
Davis Medical Center in Sacramento. His clinical training includes expertise in

His clinical interests include esophageal disorders, reflux disease management, chronic
abdominal pain, constipation, hemorrhoid banding, colorectal cancer screening, and
integrating holistic approaches into gastrointestinal care. Dr. Viramontes is deeply
committed to providing evidence-based, patient-centered care tailored to each
individual’s needs.
Born in Zacatecas, Mexico, Dr. Viramontes was raised in California’s San Joaquin
Valley alongside his three brothers. The son of farmworkers, he was awarded the
Gates Millennium Scholarship, which fully funded his undergraduate education at
UCSD. His academic excellence earned him multiple accolades, including induction into
Phi Beta Kappa.
Throughout his medical training, Dr. Viramontes led and participated in numerous
research projects across cardiology, public health, gastroenterology, and liver disease.
He completed a research internship at Brigham and Women’s Hospital (a Harvard
teaching hospital) and has authored several first-author publications. He has presented
at national conferences such as the American College of Gastroenterology (ACG) and
Digestive Disease Week (DDW), earning recognition as a clinician who delivers
high-quality, evidence-based care.
Before joining his current practice, Dr. Viramontes traveled extensively throughout
Europe and Latin America—including Mexico, Guatemala, Costa Rica, Ecuador,
Colombia, Argentina, and Brazil. His global experiences have deepened his
understanding of the human condition and reinforced his belief that patients everywhere
value a doctor who combines the best of Western medicine with a thoughtful, holistic
approach.
Outside of medicine, Dr. Viramontes enjoys an active lifestyle with his wife, Natalia, and
their young son, Maximiliano. Together, they enjoy beach walks, dancing, and spending
quality time outdoors. He hopes to share his love for soccer and tennis with his son. In
his free time, Dr. Viramontes can often be found running, hiking, or listening to
podcasts.
Dr. Viramontes believes deeply in the universal desire for connection and well-being.
From rural farmworkers to urban professionals, from the underserved to the privileged,
his philosophy remains the same: every individual deserves compassionate, respectful,
and excellent care.
