Ha, another Medics on the Ball, thought I was the only one. But pretty sure OP is brand new and they've only been hiring 2+ years experience lately.
To answer your question, a small dialysis company won't look bad, and any experience is valuable when you're starting out.
But don't get comfortable there. Don't stop looking for a better job because you've got a steady paycheck now. IFT companies, especially the shady ones, will always pay better than 911 because that's the only way to get and keep employees. If you got into this for the money, you sir made a minor error in calculations.
But take what you can get, get your feet wet, just keep making linear progress.
I'll keep pushing it because we really need people, but Liberty Ambulance in Ridgecrest is a great place to get experience and we're currently hiring EMTs.
