Radio Comms and public safety., I am a public safety/emergency services chaplain. I work mostly with EMS due to their high incidence of PTSD and traumatic stress. My degree is Christian Counseling and Psychology. I am an ordained minister but not a "preacher". You would not like me as a parish pries, I am too blunt in many cases. Sometimes that is required to get through the emergency services mind. I have been a medic for 53 years so I know the problems EMS faces because I have been them and probably experienced most of what they have.
