Unit Directors and Staff
Dr. Javier Rodriguez, Chief Medical Officer, heads up a highly qualified team of physicians and staff that represent the cultures and the community they support. La Maestra's 40+ physicians and staff collectively speak 19 languages and are selected to work at La Maestra based on their cultural expertise as well as their medical training. Many of the staff are recruited from the local community and are immigrants themselves. This policy benefits the diverse community in many ways: La Maestra is able to provide culturally competent care for our patients, and provide community residents with professional development opportunities.
Physician "medical residents" are recruited from partnerships with Children's Hospital and Health Center, University of California San Diego, Scripps Health and Sharp HealthCare, and other hospitals throughout the country. La Maestra has expanded into a main Center in the nation for professionals to receive culturally competent professional training. It is hoped that these healthcare providers will apply their new knowledge and experience to other diverse communities.
