ANNIE NGUYEN, MD, a native Southern Californian, graduated Summa Cum Laude from the University Honors Program at California State University Fullerton. Opportunities presented themselves on the East Coast where she broadened her horizons as she seized opportunities to obtain her medical degree from Harvard University and ophthalmology residency training at New York Eye and Ear Infirmary. She returned home to California to complete fellowship training in cornea, external disease, and refractive surgery at USC Roski Eye Institute.

The foundation for her approach to health care has been firmly laid to rely upon effective communication, endless quest for knowledge, constant skill refinement, and unwavering patient advocacy as she strives to provide exceptional patient care, contribute to the education of medical students, residents, and fellows, and further knowledge through clinical research.

Outside of work, Dr. Nguyen enjoys traveling, spending time with friends and family, cooking and baking, playing sports, arts and crafts, and playing with her dog.
