EMS Response Team Physicians

Not all physicians can provide effective medical care in the prehospital environment. The physicians on the Response Team have significant experience and training in out-of-hospital medicine. Many members of the team have obtained fellowship training in EMS.  All team members have advanced training and experience in EMS and the specialized capability to provide field medical and surgical procedures. Only physicians with these advanced skills and operational experience have been selected to serve in this capacity.
