Wilson Castillo began his career at a local mall at the age of 15, and was introduced to the Auntie Anne’s franchise in 1999 at age 26. He worked for Dan Margolis, a local franchisee operating 3 stores, and helped grow the company to 20+ locations through a combination of acquisitions, new store developments, and strategic sales. When Dan retired and sold the business, Wilson co-founded Fresh Dining Concepts (FDC), which was backed by a private equity firm, where Wilson assumed the role of COO.
