About Me

I had actually gone to medical school with the intention of becoming an Obstetrician-Gynecologist. Being a native of the Pacific island of Saipan, I grew up witnessing firsthand the effects of geographic isolation and dearth of providers on women's health. From an early age, I knew what I wanted to be. Clinical experiences in medical school reaffirmed my decision, and delighted me with the diversity of care OB/Gyn has to offer. I am a strong advocate for reproductive rights, patient autonomy, underserved access to care, culturally competent and evidence-based medicine and inclusive OB/Gyn care for individuals who fall anywhere along the gender identity spectrum.

It is these very passions that led me to train at UCSF! Beyond being leaders in the field in both the clinical and research realms, UCSF has demonstrated a commitment to tackling the social issues surrounding reproductive healthcare. I feel that UCSF will not only support, but encourage me in my efforts to be as well-trained, socially aware, and civically engaged a provider as I can be. Additionally, they share my vision for greater diversity in healthcare as a whole. The Bay Area itself is a real cultural treasure all its own.

In my spare time, I read and write, knit and cook--and spend as much time with my dogs (and people!) as possible.
