Biography

Dr. Justin Marasigan is a Board-Certified Gastroenterologist who was raised in the Los Angeles area. He earned his undergraduate degree from the University of Southern California and his medical degree from Kirksville College of Osteopathic Medicine in Missouri. Dr. Marasigan went on to complete his Internal Medicine Residency in the Detroit area and his Gastroenterology specialty training in Erie, Pennsylvania. He applied a variety of experiences from rural offices to large academic centers throughout Western Pennsylvania and Eastern Ohio. Prior to joining the team in Ventura County, Dr. Marasigan was practicing Gastroenterology for 7 years in Washington State.

When he is not at work, Dr. Marasigan enjoys spending time with his wife, twin son and daughter, and dog Sadie.

    My philosophy in medicine is taking a partnership-approach to each individual’s health and needs. I don’t like to tell patients what to do, but instead discuss the options, benefits and risks, and come to a decision with the patient. I was trained to treat each patient like you would a beloved family member, and I strive to do so with each visit.
