Pro does, but only in one location(Emerson hospital catchment area).
None of the rest of the list runs a real non transport program. Supervisors can function as such, but thats not the same. Armstrong(which operates in the North Shore area), runs true non transporting ALS with a number of BLS transporting fire depts in that area. Two hospital systems in the general Boston area, Lowell and Lawrence General Hospitals run true non transport services for the surrounding communities; but calling them "boston area" is really stretching the definition.
Non transport isn't nearly as big a thing around here as it should be. It sure used to be. Back in the day, paramedics ran out of several hospitals in the area, covering most of region. Most of these programs were top notch; but were phased out when more and more Fire departments decided to stop leaving money on the table and take over the ambulance. Personally, I think we were better served in times past, but that's subjective.
