New & Established Patients Call

My philosophy of patient care is centered on compassion, respect, and evidence-based medicine. Every patient deserves to be treated with dignity and to have their voice heard in the decision-making process. Just as in teaching, where I aim to empower learners with knowledge and skills, in patient care my goal is to empower individuals and their families with clear information, education, and support so they can actively participate in their treatment journey. I approach each patient holistically, recognizing not only the disease but also the person behind it—their values, fears, and expectations. By combining scientific rigor with empathy, I strive to provide the highest quality care while tailoring treatment plans to each patient’s context. Communication is central to my philosophy; I emphasize open dialogue, shared decision-making, and continuity of care. As a gastroenterologist and hepatologist, I am committed to advancing care through innovation, collaboration, and global best practices, while maintaining humility in learning from patients themselves. My philosophy is guided by service—serving patients, families, and communities with integrity and compassion, while continuously striving for excellence in outcomes and quality of life.
