Dr. Ong and the office staff care about the families they work with. It's always a nice experience to go in. They listen to my concerns, answer my questions, and offer advice. Dr. Ong has been with us since my daughter has been born. The front desk ladies are always smiling. They know me when I call. Which is special. The medical stuff is friendly and makes my daughter feel comfortable.
