In popular culture, the specter of midlife crisis often looms large at 40. But not for Marco’s Pizza. The chain, which turns 40 this year, is on the fast track to restaurant franchise superstardom. In 2016, the Toledo-based pizza chain had 17.1 percent growth. In 2017, it had locations in 35 states as well as India, Puerto Rico, and the Bahamas. In April of this year, it opened its 900th store in Puerto Rico, and at present it is on target to have 1,500 locations open by 2020.

A new Marco’s store opens every three days. As the company rings in 40, there is plenty of cause for celebration. On Tuesday, it did with a party at the Toledo Museum of Art Glass Pavilion recognizing Marco’s Pizza’s long history and bright future.
