About me
I grew up in Fresno, California, where the hot weather mixed perfectly with my love of swimming. I ventured to Auburn University for my undergraduate education and to pursue my passion for swimming at the college level. After completing my bachelor's in biomedical science, I moved back to California to attend medical school at the University of California, Los Angeles. During medical school, my husband and I welcomed 2 amazing girls who teach us new lessons every day. We moved to Santa Clara, California, where I completed my residency with Kaiser Permanente in obstetrics-gynecology. We chose to lay down roots in Portland due to our love of the outdoors and friendly atmosphere.
About my practice
As an obstetrician-gynecologist, I have a passion for helping women stay healthy. It is truly a privilege to help guide women through deeply personal and pivotal moments in their lives such as delivering a baby or undergoing surgery. I strive to provide empathetic and high-quality care to every person I see. After being introduced to the Kaiser Permanente health system in residency, I believe that it is a great model to deliver integrated health care for all members. I am honored to be part of this team.
How I thrive
I have always felt at home in the swimming pool and love being part of adult club teams. When a pool isn't available, my family and I enjoy exploring the beauty of the Pacific Northwest through hiking. My husband and I also enjoy cooking, baking, and tackling home improvement projects.
