Julia Tasi, Coordinator

Julia moved here from the beautiful island of Oahu, Hawaii and joined team SFGYN in 2014. Her first inspiration to pursue a medical career came from her mother who works in healthcare and an audacious science teacher who encouraged her to pursue a career in science. She was so eager to get going in her chosen field that she started in high school. By day she attended high school and by night she studied hard to obtain her certification as a Certified Medical Assistant and Licensed Phlebotomist. In Hawaii, she worked for a large University based outpatient clinic. Julia states “I'm ecstatic to be a part of the team at San Francisco Gynecology-I love people and being in the medical field”.
