professional societies - newwb question

Hey everybody -

So, like most of y’all I’m not your conventional born on mission to be a doctor to be a premed. But, here I am 30 years later, busting my chops to get it:). That being said anyone know of any post-college professional societies to join (preferably free)? Any advice would be greatly appreciated. Thanks!

What are you looking to gain from a professional society?
