About Me

I'm a freshman at SMU studying Sport Management with a minor in Business. I'm interested in player personnel, roster management, and front office operations, with a long-term goal of working in a professional sports front office.

Outside of school, I independently buy and sell sports cards and memorabilia through eBay and in person, generating over $100,000 in cumulative sales. Through this experience, I have developed skills in market research, pricing, inventory management, sales, and customer service.

I also support e-commerce and web operations for ManCave Memorabilia, a sports and entertainment memorabilia business with more than $1,000,000 in eBay sales. My work includes creating listings, handling order fulfillment and shipping, and helping build and manage the company's website.
