I was generalizing a bit in my post and obviously, your mileage may vary and different schools may value tech/nurse credentials more than others. But the unfortunate truth is, most M.D. schools still are not entirely non-trad friendly, choosing instead to fill 80-90% of their entering class with 22 year old biology majors without a day's worth of *paid* medical experience.
Now I fully agree that in a better world, you should be far more desireable a candidate than said 22-year-old, given your years of relevant experience. But, we don't live in that world...
Not to be nitpickey, but I wish you would not say "tech/nurse." A nurse is a licensed healthcare professional, not a "tech". Where I work most of the nurses have bachelor's degrees in nursing, what we do requires light years more skill, knowledge, and stress tolerance than volunteering as a patient care tech or nurses assistant, or whatever you mean by "tech".
Ok that's all back to discussion.
