In the case of an emergency ALWAYS DIAL 9-1-1.

PRO provides emergency medical services (EMS) to the City of Cambridge in conjunction with the Cambridge Fire, Police and Emergency Communications Departments. Additionally, we provide EMS to Harvard University and the Massachusetts Institute of Technology. PRO also responds to requests from neighboring jurisdictions for mutual aid.

Most 911 EMS calls enter the system via the Cambridge Emergency Communications Center (ECC). The ECC utilizes Emergency Medical Dispatch (EMD) to triage calls and dispatch resources based on the nature of the call. In an effort to cut response times PRO, along with Zoll Data Systems, has created a CAD to CAD interface with the ECC allowing the dispatch of an ambulance during the time when the caller may still be on the phone with an emergency dispatcher. PRO dispatchers use GPS and AVL to ensure the closest appropriate ambulance responds.

911 EMS calls that are the most serious in nature receive a response from a Cambridge Fire Department engine company, Paramedic Squad and a PRO ALS ambulance. Calls of a less serious or unknown nature receive a response from a neighborhood engine company and a PRO unit. All PRO units operate on the CFD radio frequency and are in constant communication with the ECC and responding CFD apparatus.

PRO also receives and responds to EMS calls directly from Harvard University, Massachusetts Institute of Technology, and other facilities in Cambridge and neighboring towns. All PRO dispatchers are EMD certified EMTs or Paramedics.
