Benton,

and what sort of stuff you want to assist your wife with (be specific)? I know she is a physician but are you are going to be making injections for her, draw blood, assist during surgery, dispense meds? Maybe than it would be better to go for you LPN licence and than take a wilderness first aid course.

Read EMT job description and realize that there is not as much healing there but packaging the patient and transporting them.
