About

After her experience throughout residency of caring for the Orange County population, she strives to continue providing excellent care for patients of all backgrounds and socioeconomic statuses. 

“As a general Internist, I find the most satisfaction in educating my patients on their complex medical conditions and using evidence-based medicine to help patients make informed decisions about their health.”

Excellent bedside manner with clear communication. Generally an easy person to talk to. Dr. Ngo is knowledgeable and thorough. She took the time to get to know me as a new patient and explained things in my prior lab reports that were a point of concern and I really appreciated that.

I was grateful that Dr. Ngo, DO was insightful & kind with her words & attitude. She was very helpful in explaining my medical stuff in acommon way, if you will, to where I could actually understand. She didn't rush our appointment, she listened to my reasons for having a visit, and provided helpful information. I am very relieved to have finally found a doctor I feel comfortable around.

From parking to checking in was easy; the ladies at the front desk were helpful and kind. Dr. Whitney Ngo, DO was warm and friendly, she made me feel comfortable and was realistic which I like. Along with being able to explain medical issue in a common, easy understanding way. She didn't make me feel rushed out or not listened to. Which made me feel relieved I found a doctor like her.
