Sean Presley brings nearly 25 years of retail and operations expertise to his role as 8th & Walton’s Senior Supply Chain Advisor, beginning his career at Walmart in 2001 while still in high school. During his 16-year tenure at Walmart and Sam’s Club, he advanced through various roles, including replenishment, store layout, and leadership, overseeing major categories such as fresh foods and optical.

Sean later expanded his leadership experience at Big Time Products, Great Neck Tools, and as VP of Operations for one of the nation’s largest seafood importers. 

Sean joined 8th & Walton in July of 2025. We asked him how he liked working for us so far. Here is what he had to say:  

“ I truly believe everything that I’ve done now has set me up for success in this role. Many suppliers, if they’ve been doing business with Walmart, know how to perform steps A, B, and C, but they often lack the expertise to optimize the business, establish effective processes, and streamline operations.

My background sets me up to have those conversations, and what I love most is that everything I’ve done is all about the people. Being able to just touch base and interact with so many different folks, I just love that part of my role.

We are a good company: We’re a B Corp. Everything we stand for and everything we do is just incredible.”
