At UCI Health in Orange, California, our physicians and researchers apply the most advanced medical knowledge—for cancer, cardiovascular disease, neurological disorders, digestive diseases, women’s health and more.
And they work across the University of California system to exchange knowledge with clinicians at our other academic health centers. That level of collaboration and innovation leads to better diagnosis and better treatment—for all patients across our hospitals.
Through research, teaching and healing, UCI Health has pioneered new therapies and techniques that have been adopted by institutions across the nation. It gives us the expertise to diagnose and treat rare conditions and diseases, with the least invasive methods possible.
Most important, it means that you and your family have access to the highest quality, knowledge-driven care. That is the UCI Health commitment: to bring personalized, leading-edge care to you and our community.
