I only live in AZ, I don't work in AZ but here in Prescott theres Life Line Ambulance (AMR). I've seen them obviously in Prescott, but also Prescott Valley, Chino Valley, and Dewy-Humboldt. Flagstaff has Guardian ambulance. Show Low has Show Low EMS, I'm not sure who runs in Payson but I'd guess it's AMR. Snowflake/ Taylor I'm pretty sure the FD transports there. I would tag someone in this post, but I can't think anyone that works in the AZ mountains.
