About me
I am glad to have this opportunity to introduce myself and tell you about my practice. I am a board-certified physician in developmental-behavioral pediatrics, which focuses on children with developmental disorders or delays. My specific area of expertise is in autism and related disorders. At Kaiser Permanente, I feel privileged to be working with our health care teams to attend to the developmental care of our patients.
Biography
I was born and raised in Singapore, a country known for its cultural diversity. I came to the United States for my undergraduate studies at Johns Hopkins University, followed by medical school at the University of Chicago. I completed my pediatric residency at Washington University in St. Louis and later pursued fellowship training in developmental-behavioral pediatrics at UCLA. Early in my career, I served as medical director for the UCLA Intervention Program for Children with Disabilities. Since 2011, I’ve been proud to provide care at Kaiser Permanente, where I focus on children with developmental and behavioral challenges. I stay actively involved in research, teaching, and multidisciplinary care.
About my practice
My practice focuses on developmental-behavioral pediatrics, with a special interest in autism spectrum disorders, attention deficit, speech/language impairments, intellectual disabilities, and the impact of prematurity on development. I work closely with families and healthcare providers to evaluate each child’s strengths and needs, and to create collaborative, personalized care plans. In complex cases, we use a team-based, diagnostic approach to provide comprehensive support. Our practice is known for its warmth, inclusivity, and commitment to care based on evidence and current research, and we remain dedicated to lifelong learning and mentoring in this field.
How I thrive
Spending time with my family brings me joy and balance. We love being outdoors, sharing meals, and supporting one another’s passions. I try to stay healthy through regular exercise and sports. I enjoy cultural activities, trying new cuisines, and learning new skills. Staying connected and practicing gratitude help me show up as my best self — for both my family and my patients.
