Yeah, for the most part. Not all on a first name basis (20 hospitals and a FD of 1800 people), but I know a good chunk at least by face. Pretty small works we work in.
When I started out I didn't know anyone. The more you work the more people you get to know. I know most of the nurses and doctors at our trauma center and a couple of nurses at our other hospitals.
I'm slowly learning the various firefighters and police officers in the area.
In the rural area I work in, we have a 40 member department and half of them run fire with the township we are located in. That department is only about 35 people so yes, I know every single one of them! We further provide EMS for 3 other townships and those departments have about 20 people each I think? I don't know them that well since these are tiny towns of just a couple of hundred each and I don't go on runs out that way personally more than 4-5 times a year. But we're getting to know them. Over time, I know most of the ER nurses and techs and docs in the area.
Yeah I know most of the providers in the area. We live in a very rural county and it seems like most of our emts work 2 or more jobs and its usually a different fire dept or ems squad in the same county. When we see each other its like "oh hey.....who are you with today?"
I feel like I know the majority of the firefighters from the area, as well as a good number of the police officers (helps that a few of them used to be medics...). Know A LOT of the nurses, docs, and techs from the ED as well. As far as facilities outside of the hospital, I recognize several of those staff members, but seems like they go through people like hipsters go through weed.
I know almost all of the career BLS people, all of the ED docs and the majority of ED nurses. We have a large area, but only three hospitals we routinely transport to. Also, our paid BLS folks frequently work at several fire departments, so you see them all frequently.
