 Critical Care Paramedics monitor a blood transfusion during an inter-facility transfer.


Great Falls Emergency Services was founded in 1994 Since that time, the company has grown to realize its long-range vision of paramedic ambulance service for the City of Great Falls and throughout Cascade County. Today, GFES continues to demonstrate an unwavering commitment to on-time paramedic ambulance response.

In 2007 and 2008 Great Falls Emergency Services participated in a municipal EMS ordinance process that resulted in a formal contract for providing 9-1-1 ambulance services in the City of Great Falls. Today, GFES continues to provide 9-1-1 ambulance service throughout Cascade County.

In addition to providing 9-1-1 emergency paramedic response, and paramedic non-emergency transport, Great Falls Emergency Service also provides Critical Care Transport, Disaster Response, Special Event Medical Standby  Basic Life Support service for long distance ambulance transport, and mobile Integrated Healthcare Services.
