She currently serves as the program director of the Emergency Medical Services (EMS) and Disaster Medicine Fellowship, the EMS Base Hospital Medical Director at ZSFG, the Medical Director of Alameda City Fire Department EMS. Additionally, since early 2020 Dr. Mercer has served in various roles for the SFDPH Covid-19 Response, including early coordination of scarce resources, medical surge preparedness and response across San Francisco hospitals, clinics and EMS system and later as the Covid-19 Vaccine Section Chief, leading the city-wide vaccine distribution strategy.

    Dr. Mercer’s experience lays at the intersection of EMS, public health and quality improvement.

She is also the Co-Principal Investigator for Project FRIEND (First Responder Increased Education and Naloxone), California’s first prehospital naloxone distribution program, now replicated in multiple counties across the state and supported by a grant from the Substance Abuse and Mental Health Services Agency (SAMHSA). In addition to exploring systems’ change and improvement efforts in emergency medicine clinical care, Dr Mercer has national experience in relationship-centered communication education and coaching, lecturing and leading interdisciplinary team workshops on communication and conflict resolution as a facilitator for the Academy of Communication in Healthcare. Additionally, Dr. Mercer evaluates national workforce and patient-centered efforts towards diversity, equity and inclusion in prehospital care and serves as the Chair of the Women in EMS Committee of the National Association of EMS Physicians.
