The story
The company was founded in 1992 when several regional ambulance providers consolidated into a single company. It was subsequently acquired by Laidlaw, and sold to Onex in 2004. With this acquisition, Onex formed Emergency Medical Services Corporation (EMSC) by merging AMR with EmCare. In 2011, EMSC was acquired by Clayton, Dubilier & Rice.
On June 12, 2013, EMSC changed its name to Envision Healthcare.
In October 2015, Envision completed its acquisition of Rural/Metro Corporation through AMR.
On August 8, 2017, Envision Healthcare announced that AMR would be sold to Kohlberg Kravis Roberts in a deal worth US$2.4 billion.
In March 2018, AMR merged with Air Medical Group Holdings under the new holding company Global Medical Response. Also in 2018, AMR was the main campaign contributor in support of California Proposition 11 (2018), a bill that modified California labor law to allow for EMS workers to be on-call during breaks.
In 2022, AMR was awarded a five-year, US$1.2 billion contract with FEMA to provide medical transport and support for national disasters and emergencies. The contract began on May 1, 2022 and runs through April 30, 2027.
