Bio
I am a comprehensive ophthalmologist in solo practice in San Jose since 1997. I consider myself fortunate to be an ophthalmologist. This was my aspiration since I was young, but I was unable to achieve it as I had anticipated. I started my career as a primary care internist (board certified 1992-2002) after unsuccessful attempts of obtaining a residency position in ophthalmology after completing medical school. After practicing internal medicine for 4 years I was able to obtain an ophthalmology residency in 1994.
I love what I do. I focus on comprehensive adult ophthalmology with an emphasis on cataract surgery serving a mostly Latino population in San Jose as the only Hispanic ophthalmologist in San Jose. My staff and I do our utmost to provide everyone we are privileged to care for with the best medical care we can provide.
