Thats pretty cool, I was always wanted to train on a collegiate level, but I got started a little late in the game.
I recieved my degree in Marketing, and started out working for Red Bull doing marketing events, and area coordination. Then went on to work for a marketing firm setting up advertising campaigns. Lost my job a year and half ago when the economy tanked, and immediately got ACE and AFPA certified for personal training. I quickly realized I wish I would have been doing this all along!!
Ironically, I was contacted 2 weeks ago by a beer distributor I use to do some work in regards to a sales job that I accepted...so now, I get to sell Miller Lite, and personal train!! Somewhat of a conflict of interest, but ya gotta do what ya gotta do.
I have an uncle, in KY actually, that is in health care admin, he's actually in charge of about 30 or 40 hospitals I think.
Sounds like your a "handson" type person, I would look into PA (have another uncle that is a PA and loves it). He played D1 football and also does a lot of athletic events as well. Or, I would look into physical therapy. Good luck with whatever you decide!!
