Learn more about Dr. Omondi Nyong’o, a dedicated pediatric ophthalmologist at Crescendo MD, and discover personalized care focused on enhancing vision for all ages. Concierge Pediatric Ophthalmology and Adult Strabismus Dr. Nyong’o, MD, FAAO knows first-hand that vision goes beyond the self; it bonds a family. Dr. Nyong’o’s daughter electrified him when she smiled for the first time, as he held her on his last day of paternity leave. Dr. Nyong’o earned an Sc.B. in Neuroscience Cum Laude from Brown University and his M.D. from the University of California San Francisco. He is a Adjunct Professor at Stanford University in the Department of Ophthalmology and at Lucile Packard Children’s Hospital. Dr. Nyong’o diagnoses and treats conditions that affect the faculty of eyesight, the dominant sense organ in babies and young children. His personalized approach to medicine and surgery for each child and each adult with strabismus is designed to maximize the development and restoration of one’s innate vision potential. All children maintain a unique capacity to grow and flower. Yet, up to 4% of children will suffer attenuation of this potential due to ocular disorders that blur and fade their impression of the world. The good news is that doctors can aid parents in identifying, clarifying, and overcoming these sight disorders. Since 2006, Dr. Nyong’o has supported several thousand families by collaborating with primary and specialty care doctors in Silicon Valley, the United States, and internationally. Dr. Nyong’o served as the inaugural Chair of the Department of Ophthalmology at the Palo Alto Medical Foundation (PAMF) where during his 15-year tenure he also led philanthropy and research. Among his innovative contributions, Dr. Nyong’o generated best practices for early, safe detection of sight disorders via large-scale preschool vision screenings. His work for Bay Area families is ongoing. Dr. Nyong’o brings this encompassing experience to the benefit of each family in his practice at Crescendo MD. Much like the eyes themselves must adjust their view - from receiving the wide panorama of a picturesque landscape, all the way down to focusing on the small print of this page - the full benefits of eye care unite the enjoyment of best practices for broad populations, with singular contemplation of how to meet the need of an affected individual. Referring doctors, parents and patients trust Dr. Nyong'o for his acumen, accessibility, gentle manner, and commitment to converge the immediate and long-term needs of his patients so that they may enjoy durable and brilliant vision.
