[1] Milio's was started in 1989 as a sandwich shop on West Johnson Street.

In 2004, the company began franchising and changed its name from Big Mike's Super Subs to Milio's Sandwiches.

In October 2020, close friends Brian Bergen, Timm Heller, Todd Mancusi, Tony Mancusi, and Chris Gentilli became owners of Milio's Sandwiches.

The company has been recognized for its community involvement program that was founded in 2021 and gives back to local nonprofits.

The menu also features seasonal soup offerings, cookies, chips, rotating specialty sandwiches, and more.
