Shelby Ohstrom

Social Media Researcher/Marketer

Shelby is a social media editor here at fourmangos. While she is new to the game, she strives to make sure the fourmangos brand comes across loud and clear on all social media platforms and is done so in a professional and efficient manner.  


Shelby attended Nazareth College for undergrad and received her B.A. in Legal Studies and minored in Communications and Media. Currently, she is attending Michigan State University College of Law and is working toward getting a Juris Doctor and becoming an attorney. While working with the social media of fourmangos, she also manages the social media for a local business in New York where she has continued to build upon her foundation of knowledge. In that position, she has used her skills as an amateur photographer to create social content as well for that company’s training program.  


Social media increasingly grows as a form of communication in society today and it is important to understand how to use it correctly to provide your business with a marketing edge, no matter the market they are in. Shelby works with fourmangos to do just that.
