She completed her medical training in 1993 as a fellow in ocular oncology, plastics and orbital surgery at the University of California, San Francisco. Following the completion of her medical training, Dr. O’Brien served UC San Francisco as a clinical instructor, assistant professor, associate professor, Pearl and Samuel Kimura Professor of Ophthalmology and full professor in the Departments of Pediatrics and Ophthalmology until departing in 2009.
