Who We Are
In Redwood City and the Peninsula
Home / About us
A personal practice where you see real doctors who know your eyes and your history, the entire time.
The Definition of Personalized Care
Four generations of ophthalmologists, one mission: to deliver the best eye care in the most ethical, efficient and effective manner imaginable.
Dr. Wixom Sibley opens the practice in Redwood City.
Dr. Edward A. Novak III joins and later takes over.
Dr. L. Scott Feiler joins the practice.
Longtime local ophthalmologist Dr. Thomas C. Stevenson practices here.
Dr. Philip Ngai joins as Dr. Feiler retires.
Doctors decide your care
No administrators or outside pressure dictate how we practice. Your care is decided by eye doctors, the way we were trained.
A real doctor, the entire time
A friendly welcome, state-of-the-art testing, and an eye doctor who personally performs every part of your exam. No intermediaries.
Old school where it matters
Time to listen and explain every step. We have even made house calls on occasion.

The Doctor’s Doctor
Physicians trust us with their own eyes. Our team has cared for and performed eye surgery on many fellow physicians and surgeons, and colleagues know us as the “Doctor’s Doctor.”
Every patient receives that same level of care: careful, personal and unhurried.
“As a doctor and anesthesiologist I have had ample exposure to all sorts of docs. We used to have the term for the best surgeons as ‘Doctor’s Doctors.’ He is at the very top of the list. Wouldn’t go anywhere else.”
