About
Bio
After an undergraduate business degree at UC Berkeley, I attended Yale University Medical School and then served in residency at Cedars-Sinai in Los Angeles receiving a great diversity of experience and opportunity. After seven years in Los Angeles, co-founding and operating a laborist program at two major southern California hospitals, I moved to northern California to the charming Napa Valley.
In Napa, my medical partner and I began a minimally invasive center for gynecologic surgery starting in 2002-2003. Since late 2003, we have been utilizing the robotic surgical platform known as the Da Vinci system from Intuitive Surgical. In many ways it had transformed our practice. It was here that I completed the first robotic hysterectomy in California and learned of the impressive benefits of this technology for our patients.
Now having helped several hundred patients, and taught multiple colleagues the technologic advances of Robotic surgery throughout the United States, the opportunity to follow my heart back home to southern California came as a blessing.
