All of our members are volunteers. There are approximately 32 active riding Adult members in the corps, 12 high school and 13 college students.  We also have non-riding life members and associates who remain active in the corps' business.


We respond to calls twenty-four hours a day seven days a week.  


We are dispatched by the  Ardsley Police Department. via pagers, text messages and fire horn. Upon receiving a 911 call, the Police Department dispatches a patrol car and sounds our pagers and the fire horn. All available members respond to our station to ensure that we have a sufficient crew.  Each time the ambulance leaves the station on a call it carries a driver and at least one New York State certified EMT (Emergency Medical Technician).  We usually respond with a crew of four from 6:00 AM to midnight.  From midnight to 6:00 AM  we have assigned crews responding to calls.  A specific crew will be on call for three consecutive nights every eighteen days.  When the pager goes off on a crews' assigned night, only those four volunteers respond.

We can also be dispatched by 60 control, which is a division of the Westchester County Department of Emergency Services.  ASVAC is part of the quad village/county mutual aid plan. If Dobbs Ferry, Hastings or any other community is out of service, unable to respond or needs additional resources, 60 control will request we be dispatched on a mutual aid call.

Advanced Life Support (ALS) is provided by the Greenburgh Police Department who meets our ambulance on the scene via their fly car.  If necessary, a Greenburgh Paramedic will accompany the patient to the hospital onboard our ambulance in order to provide ALS level care.

We transport our patients to the nearest appropriate hospital which might include St. John's Riverside Hospital Dobbs Ferry Pavilion, White Plains Hospital or Westchester Medical Center.
