excellent experiences
June 26, 2026
When I call the building customer service, the details are very bad and impolite and it's not helpful and everything is not good. Please adjust their customer service.

Dr. Ong shows a lot of compassion and caring for the children that he sees. He doesn't play around or hesitate to make a decision. He uses his knowledge as a doctor to give an explanation and also to give any possible solutions and alternatives for the child's care. Like many other doctors on PIH, Dr. Ong is an excellent pediatrician.

Dr. Ong and his staff are the best. My one have been seeing him since my oldest (now 17) was born. The care and attention they give are amazing!

The staff at PIH are wonderful! I love how they care for my daughter and show her love. Please continue to be awesome. My daughter loves the little gifts you give her. Thank you Dr. Ong/(name removed)/ and staff!

Dr. Ong entered the room and said hello to us but didn't make eye contact with either my husband or myself. He walked straight to the computer as he was talking. This was our first visit with Dr. Ong, but whether this was our first or 100th visit, acknowledging the patient and the family with eye contact and a small smile is so important. It helps the visit start on the right track and helps build trust.

Dr. Ong is a great, very attentive pediatrician. He does not give the round around. He does not wate time in the kids health and gives a quick solution.

Thank you to Dr ONG, and his staff. They were very friendly and professional and even though their system wasn't working they made our first visit very good. We had been looking for a good Dr for a few months now and the boys really liked Dr ONG. Also their office is very clean!

Dr. Ong has been my son's pediatrician for several years, and I truly can't imagine what we would do without him. He is an exceptional doctor-kind, attentive, and incredibly knowledgeable. We are so grateful for the care and dedication he has shown our family. We appreciate everything about him.

Dr. Ong is amazing. He's been my pediatrician since my 16-year-old was born. So he has been in our lives for a very long time. So there's absolutely nothing but wonderful things to say about him as a pediatrician.

Dr Ong was great
February 12, 2026
Everybody's super friendly, but your automated system to talk to someone inside the office is a nightmare. I can't get to somebody in the office. I can't get an extension to call back directly, and I hate that. It is the only complaint I have about you guys. You need to be able to give the receptionist or the nurses an extension where I can call them back directly without having to go through the automated system and having to explain my problem to strangers every time because nobody's available.

Dr. Ong is caring and knowledgeable. He makes for a great pediatrician.

There was a language barrier since the receptionist as well as with the nurse and the doctor. I felt I did not fully understand what they were telling me.
