imo, your profile is pretty interesting and that will work to your advantage. you have a pretty solid undergrad degree and your GMAT score is on the low range of acceptable at some of your more competitive schools, so you're in the mix. you also have an impressive set of ECs which stands out (most candds have an EC focus on tutoring, which is great, but doesn't stand out as much as the things you've done).
there are 2 challenges you'll need to address:
1) while i'm sure the org you work for is excellent, many hospital systems are regional in nature and do not a strong brand. you'll need to weave into your essays why your org is so competitive and how your leadership there is a big deal. you don't want it to come across as though you've made all this career progress at a small business. it's not like you did these things at GE which everyone knows and respects. you'll have an educational component to your application to present.
2) your career goal of management consultant feels reasonable, but it also feels like a cop out. get more crisp on why you want that, how long you'll do it for, where you want to do it, how you'll get a job doing it, etc. if you select this as your career goal, just make sure the position it strongly. there are so many candds who will state this as their career goal, and it all starts to blur together to a point (if you're on the adcom) where it just feels generic and non-special. don't be that guy.
as long as you get all the other pieces out there, i think you have a compelling story.
hope that's helpful,
