Thing is,
@gonefishing hit the nail on the head. I started in 2002 when AMR had the whole kit and kaboodle in that particular EOA. I had seen it go from AMR to CARE overnight (sound familiar?)
When CARE sucked up this rather large area--and just to be clear, this is was what literally got their foot in the LA County door--they went through the same growing pains, probably more. They in-housed a multitude of OC folks with AMR-turned-CARE folks (these guys and gals were overnight employees with jobs in hand because of such leverage) to help them get familiar with a county this company largely had zero experience with. This is probably how and why the AMR Irwindale and Schaefer folks thought they would have jobs immediately. They had in many years past going back far enough into even the Goodhew, Adams, and Crippen Ambulance days.
If Sergio Montoya still works there ask him yourself about his company being taken over by AMR and how they drove AMR ambulances in their company uniforms until it was all sorted out.
All of these ex-AMR employees were co-workers at my division (many still work for CARE) who knew they would not, or could not ever leave Los Angeles County. They hounded many of us to switch over because life was "better". I can distinctly remember an AMR-supervisor-turned-CARE-supervisor overnight hanging out at the entrance to our station to try and recruit us; they would eventually be escorted off of the property, lol.
My partner and a couple other good buddies and I stuck it out til the end of our division, then we all went our separate ways. I eventually applied for CARE after turning down another AMR division transfer. When I did my interview and test it was halfway like being interviewed by your long-time colleagues and a few other administrators they had working there at the time. It was standard stuff: a written test, skills station, etc. nothing really dazzling or different than any other private EMS company on the planet.
So yeah, I have just a smidge of experience with the company and it's history within this county you are inquiring about. Also, some friendly advice
@Abbey- if you're flying off of the handle this easily over some post by a total stranger you hardly even know, you have a long road ahead of you. This industry is incredibly small in all sorts of ways.
