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.

Suggestion: The staff member who handled my phone booking seemed unprofessional and very slow-the call took nearly 20 minutes. She also could not explain why my child's annual physical cannot be scheduled shortly after his 7/15 birthday. She was told that because last year's physical check was in August, this year it must be on/after 8/11, and next year would have to be even later than that. Please clarify this policy and allow scheduling any time after the birthday if possible.

The staff members were incredibly rude. Retaliate against us when I disagree with their treatment of us. After being to this office for over 19 years, this office's services, quality of both staff members and physicians have declined significantly. The doctor was insensitive to the teenager and gave responses before a question was completed. Answer was illogical and insensitive. We will be changing doctor office after this experience after close to 20 years.

Lobby secretary and Doctor was great, kind, helpful and respectable. Nurse was not very friendly and was put off a sour mood.

Dr. Ong has been by far the most consistent and best Pediatrician we've encountered and both of my children have remained under his care through the years. He's thorough in his examinations and very attentive to any concerns we have.

The very first nurse (I believe she is new?) who asked questions about vital was not too friendly especially considering it's a pediatric Drs office

The doctor's office, the doctor and everybody working there was amazing. They are great. However, this survey is longer than it should be.

Dr. Ong is very professional, you can see how much he loves his profession and his patients. We love DR. O g & his entire staff, they are always so helpful, kind, welcoming and caring. They make our children feel comfortable and not scared of coming in to see them or the doctor. I highly recommend Dr. Ong and his office to everyone: friends and especially to all my family members.

Dr. Ong has been my son's pediatrician for the past 13 years and has received excellent care. Dr. Ong always takes time to talk to my son and myself about any concerns and spends time listening to us. The staff is just as professional, kind, and courteous. I've never had an issue and aways recommend Dr. Ong and his staff on Facebook to any parent searching for a pediatrician.
