Christy Gillenwater is resigning as president and CEO of the Southwest Indiana Chamber to become president and CEO of the Greater Chattanooga Chamber of Commerce.

In June, Gillenwater was named Chamber Executive of the Year at the annual conference of the Indiana Chamber Executives Association. In 2015 she led the Southwest Indiana Chamber to be named Indiana Chamber of the Year by ICEA. She also led the Chamber to be named the 2016 National Chamber of the Year by the Association of Chamber of Commerce Executives.

Gillenwater earned a Bachelor of Science in Public Affairs from Indiana University and a Master of Business Administration from Ball State University. Her planned start date for her new role is December 1. Tim Hayden, chief communications and engagement officer for the Chamber, has been named interim president and CEO and will be working closely with Gillenwater on transition in the coming weeks, until a national search can be completed and a permanent replacement is named.
