Orthodox Jews, many volunteers see each other daily during prayers, and especially on Shabbat. This allows them to remain organized, despite the lack of an extensive formal hierarchy. The coordinators are responsible for recruitment, interaction with municipal agency operations (police, fire, and EMS), first-line discipline, and day-to-day operations. The coordinators often are responsible, directly or via delegation, for arranging maintenance crews, who are often called service members or service units, and for purchasing supplies, ambulances, and other equipment. There is also an administrative function, often separate from the coordinator function. The chief administrator is often called a director or executive director, and this is sometimes a paid position. All other positions in Hatzalah, including coordinators, are held by unpaid volunteers. Most of the New York State branches have some centralized administration and dispatch functions, known as "Central Hatzalah", or, simply, "Central". The neighborhood organizations under Central are nevertheless independent. Most Hatzalah organizations pattern themselves after the Williamsburg and Central models (see operational descriptions below). Formally, the New York City-area "Central Hatzalah" is called Chevra Hatzalah of New York. It combines dispatch and some other functions for over a dozen neighborhood organizations, including Williamsburg, Flatbush, Borough Park, Canarsie, Crown Heights, Lower East Side, Upper West Side, Midtown, Washington Heights, Queens, Rockaways & Nassau County, Seagate, Catskills, Staten Island, Riverdale, and others. As each of these areas is otherwise independent, each has its own fund-raising, management, garages, ambulances, and assigned members. Rockland County, NY and Kiryas Joel (Town of Palm Tree) branches have a centralized dispatch system as well, but their central organization is separate from the other New York State centralized functions, and they have a looser relationship with their New York State brethren, though there is a great deal of co-operation among them. Together, the combined New York State branches have grown to become the largest all-volunteer ambulance system in the United States. In 2019, it was announced that NYC Hatzoloh, one of the largest volunteer ambulance corps in the country, would receive funding from the city council. Within Israel, the largest local organization is Magen David Adom. Outside of New York and Israel, there are many smaller Hatzalah organizations. Each of these operates as a self-contained unit as members of a single association, but with no centralized coordination. However, where there are other Hatzalahs nearby, there is often a great deal of co-operation. In Baltimore, Hatzalah's response area straddles
