for undergrad i started as being a nursing major while completing the pre-med requirements (they really go hand-in hand). there was drama in the nursing department my junior year and i changed majors second semester to health science focusing on health promotion and wellness and dropped the premed. i went to grad school for healthcare management and hospital admistration.
first i was teaching medical assisting and medical office management at a vocational school for low-income single parents. after my contract was up there, i got a job with the medical society administering the county's federal grant-funded program that provided basic medical and support care to people with HIV/AIDS until the feds cut NYS health department by millions of dollars. then they got some poor slob college intern to answer the phones and "redistributed" my workload over a bunch of people that were already overworked.
fastforward through being unemployed then working a factory job so that i didn't have to file for bankruptcy, i'm working for an orthodontist as a dental assistant. NYS changed it's law this year and i'm currently back in "school" for a new certification, even though i could teach these classes. they're really the same thing as medical assisting, just more focused on teeth than the body as a whole.
