pa's who work A LOT in a specialty can make 200k. one of my partners does but he works 24-26 days/mo., I work 17-18.
docs hire pa's to do the work they don't want to do at the times and places they don't want to do it so they can be home with their families at night and on holidays, spring break, etc.
docs in my group work around 100-110 hrs/mo. for >350k/yr
most pa's in my group work 160-180 hrs/mo for 135-150k or so depending on production.
