Looking for Mentor

Hi everyone! 

I'm currently in the midst of applying for entry level master's programs and was wondering how I could find a mentor in the event that I do not get accepted this first round of nursing applications.

I've definitely narrowed my scope as far as my specialty for when I do get into a program. I am interested in Pediatrics in the Neuro-Med population. 

Are there sites out there that can help me find one? 

I'd love to utilize as many resources as I can to better my chances for the next round. 

Thanks for all the suggestions in advance!
