Dr. Ester Kwok is an internal medicine physician who works with adults ages 21 and older.

She empowers her patients by giving them the knowledge and tools they need to take control of their health. Dr. Kwok is inspired by the opportunity to prevent illness or make timely diagnoses that can change the trajectory of not only a patient's life, but the lives of everyone interconnected with the patient.

"I believe that I am here to serve others with love. I use my faith to renew me so that I have the empathy needed to care for others," Dr. Kwok explains. While empathy is important in the patient-doctor relationship, she believes honesty is equally important. She's willing to have difficult conversations with patients who may not be participating in their care as needed to help them improve their health.

To get the most out of your visit, Dr. Kwok recommends coming in prepared. Be ready to discuss your most pressing questions and concerns. Think about what has made your issues improve or worsen. If you've been to a specialist or have had testing done, let us know before your appointment, so we can gather the information or results ahead of time.

Dr. Kwok is proud to be affiliated with El Camino Health, which has been recognized among the top 15% of U.S. hospitals for outstanding patient experience. She enjoys collaborating with colleagues to contribute to the strength of the organization because that ultimately results in better patient care.

Outside her practice, Dr. Kwok enjoys taking walks with her family, gardening and keeping up with current events. She likes to start each morning with quiet time to get ready for whatever the day may bring.
