As far as critiquing your individual resume, here'* what I think in no particular order of importance:
I would bullet your computer skills list
Make sure everything is evenly spaced (last lines of a few of your jobs have an extra space in between lines)
2nd line of the diabetic foot management center should read "Assist patients into rooms"
I would put when you recieved your Associate degree (month/year should be fine)
Arrange jobs in chronological order starting with most recent on top. (this I think is important)
Just saw this thread. Darcy literally took the words right out of my mouth. Attention to detail is VERY, VERY important, IMO when it comes to resumes. Think of your resume as your first crack at selling. Selling yourself.
Congrats on the interview. However, you should still make the revisions.
I have been thinking of a term that one of my english teachers told us, but couldn't remember it until now. Parallel structure. Make sure all your info is laid out in the same style/format throughout the resume. Keep everything in the same tense (past/present), use the same bulleting style from one section to another, etc.
