Meet Our Doctors

Dr. Andriani Ongkorahardjo

Dr. Andriani has been dealing with the oral hygiene needs of children for over twenty years. After graduating from USC School of Dentistry, receiving her CAGS in Pediatric Dentistry from Boston University, and receiving her Fellowship in Pediatric Dentistry from the University of Illinois at Chicago, she has been dedicating her career to providing the highest quality standards and the most modern techniques in Pediatric Dentistry. Her experience, knowledge, and dedication are only surpassed by her heartfelt desire to personally provide the highest quality of service in a fun, caring, friendly, and educational manner for each individual child.
Dr. Andriani comes from a family with a strong history in the medical field. Her father is a surgeon and her brother is an urologist. Despite the gentle coaxing from her family to enter the medical field, Dr. Andriani pursued dentistry with an emphasis in pediatrics. She has a deep desire to improve on the way children are care for and treated.

Dr. Wu is focused on achieving perfection and finds immense joy in sculpting beautiful smiles and simultaneously improving the quality of life of his patients.
