About MCEMSA

The Mountain Counties Emergency Medical Services Agency (MCEMSA) is the local EMS agency for Alpine, Amador, Calaveras, and Mariposa counties. We are a Joint Powers Authority formed by our four member counties and authorized under California's EMS statute (Health and Safety Code, Division 2.5) to plan, coordinate, and regulate the emergency medical services system within our region. Every ambulance response, every paramedic, and every EMS training program in these four counties operates within the system this Agency oversees.

What We Do

Most residents never interact with MCEMSA directly, and that is by design. Our work happens behind the 911 call, setting and maintaining the standards that determine what happens when an ambulance arrives.

• Medical direction and treatment protocols. Our Medical Director establishes the treatment protocols that EMTs and paramedics follow in the field, so a patient receives the same standard of care anywhere in the region.
• Certification and accreditation. We certify Emergency Medical Responders and EMTs, accredit paramedics, and authorize Mobile Intensive Care Nurses practicing within the system. Certification processing is handled online through this website.
• Training program approval. We review and approve the EMR, EMT, paramedic, and continuing education programs that train the region's EMS workforce.
• System evaluation and quality improvement. We continuously review system performance and field care, identify problems, and work with providers to correct them.
• Disaster medical preparedness. We coordinate the medical and health components of disaster planning and response for the region, working with county health and emergency management partners.
• Public information and education. We support community programs that improve outcomes before help arrives, from AED placement to CPR awareness.

The Region We Serve

Our four counties cover a large and demanding piece of California, from the Central Sierra foothills to the high country along the Nevada line, including gateway communities to Yosemite National Park. The permanent population is small and widely scattered, but visitor traffic multiplies demand seasonally, and mountain terrain, winter weather, and long transport distances shape how EMS must operate here. Delivering the same quality of pre-hospital care in this environment that a patient would expect in an urban system is the central challenge of this Agency, and the reason a coordinated regional system matters.

How We Are Governed

MCEMSA is governed by a Board of Directors made up of a member of the Board of Supervisors from each member county, appointed annually. The Board sets policy, approves the budget, and adopts the standards, protocols, and procedures under which the system operates. Day-to-day administration rests with the Executive Director, who is appointed by and answers to the Board. The Medical Director, a licensed physician, is responsible for the medical control of the system. Advisory committees of providers, hospitals, and county representatives study specific issues and bring recommendations to the Board.

Working With Our Partners

EMS is delivered by people who do not work for us: fire departments, ambulance providers, hospitals, flight programs, dispatchers, and county agencies. Our job is to make those pieces function as one system. We write the framework, verify the qualifications, measure the results, and coordinate the planning, so that the crews in the field can concentrate on the patient.
