Non-Trad Success stories?

For context I'm a 25 y.o. 3.5 GPA Finance degree graduate from a small university.
Been working family business in construction basically my entire life. Have been wrestling with the idea of taking my pre-reqs and MCAT for practically a few years now.

I really believe I can score highly on the MCAT and in my science courses. I signed up for the volunteer EMS in my area and have an interview coming up, also been applying to medical assistant jobs at local hospitals, theres lots of volunteer opportunities in my area so that shouldn't be too much of a problem in the next 2-3 years

I would really like to hear some of your stories or if any of you know Non-Trads who got in with lower GPAs and what their stats looked like. Also is MD completely out of the question?
