About me

I was born and raised in Los Angeles. As an undergraduate, I studied literature and natural sciences, then completed my medical education and training at the University of Southern California in Los Angeles. While at L.A. County Medical Center I chose to pursue a career in women's health and, specifically, training in women's cancer care. I am dedicated to providing top-of-the-line care to my patients, and I believe Kaiser Permanente is the institution that allows me to do so best.

About my practice

Gynecologic oncology is unique in that one doctor provides both the surgical and medical therapy for a patient with cancer. I treat all gynecologic cancers including, but not limited to, those of the uterus, ovaries, and cervix. I specialize in complex pelvic surgery and perform minimally invasive surgery whenever possible. In particular, I am interested in precancerous lesions of the female genital tract, including the cervix and uterus, and have published research on this topic. I am also interested in surgery to address genetic abnormalities such as BRCA 1 and 2 and Lynch syndrome. Ultimately, I strive to provide comprehensive and innovative care to my patients. I practice individualized patient care to ensure that all of my patients receive the best treatment options available and that they feel cared for in the process.

How I thrive

When I’m not working, I enjoy spending time with my husband, 2 daughters, and my extended family. I take great pleasure in watching my children learn and grow. I continue to be an avid reader of both medical and non-medical texts and love listening to live music with friends.
