Audrey Simons

Audrey Simons, CEO

Audrey Simons, MSHA, has served as CEO of San Fernando Community Health Center (SFCHC) since 2013. She has spearheaded the organization's transition from a community hospital to a state-of-the-art Federally Qualified Health Center (FQHC) that provides a full complement of medical, dental, behavioral health and education services for the entire community, with an emphasis on the most vulnerable and chronically underserved.

Under Simons’ leadership, SFCHC has experienced unprecedented growth – with a 284 percent growth factor from 2016-2019 – as it continues to remain true to its nearly century-long legacy as a treasured health resource by enhancing community access to high-quality primary care services. Major projects completed in the last several years include building out the SFCHC Primary Care Center, expanding the Dental Clinic and opening a satellite clinic in Mission Hills.

Prior to joining SFCHC, Simons served as Administrator of Community Benefits/Grants for the San Fernando Campus of Mission Community Hospital for 10 years. In that position, she was responsible for all community benefits programs and oversight of capital projects, plus wrote and administered grants.

Simons is actively involved in several community/civic organizations, including serving on the Board of Directors for the Valley Cares Community Consortium. She holds a Bachelor of Science degree in dental hygiene from Loma Linda University and a Master of Science degree in health administration from California State University, Northridge. Simons practiced as a registered dental hygienist in the San Fernando Valley for nearly 30 years.
