ya, I did. I have been a paramedic with this service for 5 years and really wanted one from the medical director-felt it might look better. However, because of the nature of his job and my schedule we never really got to know each other. Instead I asked my direct supervisor whom I may have only worked the streets a handful of times with, we were in very close contact. I felt he could better speak to my motivation, compassion, aptitude, despite our not being on the same truck very often.
I think when it comes down to it, this is what adcoms want to hear about-not how well you can backboard someone, or how proficient you are at applying oxygen or any of that garbage. I think they want to hear more about you as a person, and I have a feeling if you have been at your service a while, then your sup can speak to this.
