Suzy Cook

Hospitality Director 

Hello! My name is Suzy Cook and I recently moved to Arizona from Florida to be near my daughter. As a Florida native the Arizona sun looked inviting! My sister is a Chick-fil-A Owner/Operator in Brandon Florida, so my love for Chick-fil-a is a family affair! Being "cut from Chick-fil-A cloth", hospitality is the name of my game. I look forward to welcoming you soon at our Chick-fil-A!
