Where I practice
About me
I was born in the Philippines and soon moved to New York City, where I grew up in Spanish Harlem. My mother was a physician, exposing me to the field of medicine at an early age. Even then, I knew I wanted to pursue a career in medicine. My passion lies in providing comprehensive women's health care and serving my community. I attended undergraduate and medical school at Georgetown University, in Washington, D.C. After completing my training in obstetrics and gynecology at the University of Hawaii, I joined the faculty there as an attending physician and assistant professor. I'm excited to continue my practice with Kaiser Permanente, supported by my loving husband, my beautiful young daughter, and our curious cat, Molly.
About my practice
My professional philosophy is to treat every patient individually—recognizing that each person's abilities, struggles, and goals deserve my respect and attention. I strive to provide comprehensive health care to women in the areas of prenatal care, gynecological procedures, and surgeries, as well as obstetric services. Even if a problem falls outside the scope of my specialty, I know that it is my responsibility to help my patients receive the care they need to lead healthy lives.
How I thrive
My years in Hawaii taught me the importance of mindfulness, balance, and generosity. I consider myself a life-long learner and believe that increasing my knowledge of the world impacts my professional practice. Therefore, I enjoy traveling, being in nature, exploring cities, trying new foods, and discovering how others live and thrive. These experiences allow me to more mindful of the richness in the diverse backgrounds from which my patients come, while also allowing me to learn about how my own background affects who I am as a physician and global citizen. Balance means exercising the body as well as the soul. Hiking and running help me energize my day, while cooking and baking allow me to unleash my creativity. Generosity and kindness help center all aspects of my life around a single purpose: To serve others.
