Marcellus Ambulance Volunteer Emergency Services was incorporated under the Village of Marcellus in 1996. The organization has since become independent, holding its first independent elections in 2004. 

MAVES is made up of a combination of paid and volunteer staff consisting of 2 fulltime paramedics, 10 part-time paramedics and 32 volunteers. 

The ambulances provide Marcellus with both basic and advanced life support and transportation. The Medicar provides advanced life support. 

In addition to serving the Town and Village of Marcellus, MAVES provides mutual aid service to Howlett Hill, Navarino, Amber, Otisco, South Onondaga, Shepard Settlement, and Skaneateles.
