Bio

I am currently in my senior year at the University of Arizona, majoring in journalism with a minor in sports management. I've been running a fantasy football account on Instagram since 2015 (@Fantasy.footballexpert) that currently has over 70,000 supporters. I've also been with the sports desk of my school newspaper (Daily Wildcat) since my freshman year where I'm currently the assistant sports editor. I've covered football, basketball, baseball and a little bit of tennis over the last couple of years.
