This is the latest installment in a series that highlights major executive changes at top fast casual, QSR and casual dining chains over the past week.

Brands undergoing turnarounds, namely Red Robin and Subway, have been particularly active in finding and hiring new executives this year. Subway hired four new executives in various positions, namely Carrie Walsh as chief marketing officer, this week, just months after it named a new CIO, chief brand and innovation officer, director of convenience innovation and senior corporate executive chef.  Red Robin named a new board chair two months after it appointed three new, independent board members and a month after it hired a new CEO. New executives could be key to bringing back positive same-store growth for both of these brands.
