Dr. Ernesto Ong is a very caring and knowledgable doctor who takes the time to listen to parents'concerns and knows his patient well to offer good treatment plan. IRS very nice of him to call a few days later to check on how my son is doing, if he's getting better.

Very caring, great with follow-up and very encouraging of questions and concerns. Didn't seem like he was just rushed to move onto the next patient.

The provider has been very nice and explained things in details.
March 12, 2018
Excellent doctor!
March 02, 2018
We waited over 1 hour before we saw the provider. We know it's the flu season and the weather change with a lot of sick children. Perhaps not to schedule so many back to back appointment for the provider. So the provider has sufficient time to see each of his patients. Especially these are children.

Dr. Ong is the best! Very professional, knowledgeable and patient. We’ve been seeing him for 14 years. We had to change doctors for a few years because we moved. Now we are back in the area. First thing to do was to change the kids’ primary physician to Dr. Ong again.
December 14, 2017
Doctor Ong is honest and straight forward. We appreciate the direct communication regarding our girls. His approach to our daughters health care is right on!

Dr Ong is a caring pediatrician and takes the time to listen to your concerns. He doesn’t rush like many other doctors do and he always asks you if you have any further questions. I’d recommend him to others. The wait time sometimes could be 30 minutes though depending on how busy they are, even though you arrive before your appointment time, so I feel that could be improved on.
