Rebecca DiMundo, MD, FAAP

Dr. DiMundo is board certified in Pediatrics and licensed in the state of California.  She is also a member of the American Academy of Pediatrics and the Los Angeles Pediatrics Society.  As the owner of the practice, she shapes the care of each child into a conscious, creative, and family-focused plan that leads children and their parents from infancy through adolescence.

Dr. DiMundo was born and raised in West LA, where she attended local schools (Walgrove Elementary, Mark Twain Junior High, and Venice High School).  After high school, she spent a year living with a family and studying Spanish in Ecuador through the AFS exchange program.  She then attended the University of California, Davis where she obtained degrees in Spanish, Human Development, and Biological Sciences.  Medical School followed at the Keck School of Medicine at the University of Southern California, then an internship and residency at Women's and Children's Hospital of Los Angeles County - USC, downtown.  The hands-on, academic, and public health focus of her training led to a scholarship with the National Health Service Corps.  Spending almost five years bringing care to underserved communities in first Texas, then Central California, was thrilling and humbling, but ultimately her desire to be back in Los Angeles and closer to family, brought her home.
