Okay, let's start digging into this. First, you say you took the MCAT and got a 514. How many attempts did you have and if you took it more than once, how long ago were other scores attained, relative to when you got your high score? All too often, applicants get a score after a number of attempts and think that is it, when their entire testing history suggests that they may not be that person. If you take tests within a close window, they may be averaged with prior scores.
Second, there is no such thing as a non-traditional applicant anymore. In fact, what we used to consider as a non-traditional applicant is, by the numbers, the traditional route.
You say you had a 3.85 post-bac. Does that mean (as it should) that those are undergraduate-level courses? Post-bac classes from an admissions perspective implies undergrad classes taken after getting an undergrad degree. Graduate-level work, though often called post-bac is not post-bac work. So, clarify if necessary. I will assume you are using the proper terms for my discussion below.
Your undergraduate cumulative GPA at 3.3 is a problem. Particularly since your BCPM metric is likely to be lower than that. You may need to consider a graduate-level certificate or degree that is majority science-based to offset that. You would need to finish that course of study and do well in it with a 3.5 GPA or higher to start offsetting your deficiency.
You are great on research and clinical exposure -- move onto fixing things that matter now.
Your service, though a lot of hours, may not come off as the best sounding activity....coaching. A lot will depend on how you described it. You said yourself that you listed it as leadership; that can be a big problem. This brings up a big issue for a lot of applicants; descriptions are CRITICAL. Admissions reviewers only know what you tell them. When you are sloppy, less than forthcoming, evasive, and/or ambiguous with how you describe things that is reason alone to hammer an application upon review. This is especially true when applicants already have some clear deficiencies.
That is what I see right off the bat. You can clarify as you wish.
