If you want to work in that field, have you considered taking a course - at a community college or even a Junior College - that would qualify you to be a medical secretary. There are specific courses one needs for these positions - knowledge of medical terms for example and of course word processing software skills and so forth. Many schools also place students for a work term and you can cite that as experience and get to know what kind of medical work you would like to do. Medical transcription is another similar field. There are even online programs, for ex: http://www.active-online-courses.com...secretary.html
My own secretary has a Bachelor's degree in Business - which she completed while she was working. She had a diploma as a medical secretary when I hired her and had worked at a hospital as an administrative assistant.
You could also volunteer at a hospital and offer to help with archiving records or helping out in the many offices. Or you could find a job not in that field and take courses in what you ultimtaley want to do at the same time. The shorter route though is some kind of course. There are too many people with degrees and experience of some form or another at a hospital. There are also certifications provided by Hospital Associations that you can take once you are working at a hospital - say you start as a clerk and then move up. You could say work in an Admissions Department and obtain experience, taking courses at the same time. Or, work in a billing or Records management office and take the relevant courses.
I have to admit I would NOT hire someone without the requisite education, experience and backgound - but I would certainly give serious consideration to someone who had volunteered at a hospital and thus understood the medical system and had taken some courses at the same time. A colleague of mine has his wife working for him and even though she has a degree in social work, she is taking anatomy and phsyiology this term so she can better help him. You have to take into account that doctors just do not have the time to train someone to do the job. We really need someone who is a critical thinker, works well as a team member, comprehends the medical system and its terminlogy - since s/he has to handle correspondence and other documents and has excellent computer skills -especially in word processing. My secretary continues to take courses all the time and now is studying HTML but also has almost completed her certification as a Certified Health Executive. (which many hospital administrative assistants also take to move up into hospital admin).You could also start out as a receptionist at a hospital or medical/dental clinic and move up from there.
I hope this is helpful. Good luck!!
