Helloooo! I am just south of Fort Worth. In Johnson County. There are several services. A few of the bigger ones are Careflite, Medstar, AMR. All three are good services. Everyone has their falls, bet definitely fast paced because their in the city. More rural areas are Somervell, Hood Co, and Bosque county. Just depends on what he's looking for. The larger systems are a bit harder to get. There is also Everman EMS (South of FW).. Mansfield is East of Johnson Co. Only one I would advise.. Stay away from is Lake Whitney... my that is just my own personal opinion. Good Luck! Anything else just ask.
