Greenwood Emergency Vehicles was incorporated in Massachusetts in 1979 as a dealer for Emergency One, Inc., which is one of the largest manufacturers of fire apparatus in the United States and is a true innovator in the field of fire apparatus construction. Back in 1974 E-One built the first aluminum fire truck and literally revolutionized the industry. Today, aluminum is recognized as the material of choice in the construction of apparatus and it’s non-corrosive properties have added years to the life expectancy of these vehicles. Greenwood serves as the exclusive dealer for E-One in Massachusetts, Connecticut, Rhode Island, Maine, and Southern New Hampshire.
