Overview
As a gastroenterologist, I treat a full range of digestive conditions—from routine colon cancer screenings and esophageal evaluations to advanced care for complex gastrointestinal diseases. I specialize in inflammatory bowel disease (IBD), including Crohn’s disease and ulcerative colitis, using the latest biologic agents and immune-modulating therapies. I also manage autoimmune liver disease, viral hepatitis, and perform advanced endoscopic procedures such as polyp removal. While I am trained in cutting-edge treatments, I strongly emphasize prevention, nutrition, and lifestyle changes as foundations of long-term care. I believe in listening closely to patients, exploring all options, and developing personalized care plans that align with their goals. Having practiced across three continents, I bring a culturally sensitive, patient-centered approach. Outside of work, I enjoy traveling, hiking , taekwondo, and spending time with my family.
