Meet The Team

Dr. Perlita Perez-Marcia

Born and raised in Oakland, California, I consider both the Bay Area and Southern California as my homes. I knew that I wanted to become a doctor when I was in high school, so I set my eyes on University of California San Diego for undergrad, where I majored in Biochemistry & Cell Biology. I had the opportunity to return to the Bay area to attend both medical school and Family Medicine residency at University of California, San Francisco. Learning the art of being a physician while at San Francisco General Hospital gave me the tools and experience to help underserved patients and the communities that they are a part of. I worked at La Clinica de La Raza in Oakland after residency for a year where I maintained my skills in Labor and Delivery and lead the Spanish Diabetes group.

I moved to Los Angeles so that my husband could attend medical school and I have been working at Martin Luther King Community Hospital Outpatient Center (MLK) for the last three years. In addition to providing primary care in the Patient Centered Medical Home, I also lead a Chronic Pain Group for patients. We practice using non-medication methods for pain management. I have enjoyed becoming part of the MLK community and I continue to learn how to manage the struggles of one of the most underserved populations in the city.I have been on the Charles R. Drew University of Medicine and Science faculty for two years and enjoy precepting 1st and 2nd year students for their longitudinal clerkships.

Outside of practicing medicine, I love going to museums, exploring Los Angeles and spending time with loved ones.
