First Call Ambulance Service has purchased Eaton, Ohio-based EMT, Inc., the companies announced today.

Terms of the deal were not disclosed.

The acquisition — the first major expansion for Nashville-based First Call outside Tennessee and Mississippi since the company started in 2004 — boosts the First Call fleet by more than 100 vehicles and increases the company’s employee headcount to approximately 1,000.

The combined company will service more than 250,000 patient transports annually and operate nearly 250 vehicles in 17 locations across Tennessee, Ohio, and Mississippi.

The EMT acquisition is the latest in a series of recent growth moves for First Call. Last October, First Call purchased Allied EMS, a private ambulance provider located in Newport and Morristown, Tenn., and landed an agreement with Cocke County, Tenn. to provide 9-1-1 services. In addition, First Call acquired the assets of Magnum EMS in September and Medic Ambulance Company in February, operating primarily in the Newport and Memphis markets, respectively.

“EMT is a great fit for our organization because our company cultures are both focused on patient safety and quality care, and exceptional customer service,” Mike Ross, First Call chief executive officer, said in a release.
