This event is free to attend if you are an active member of the Cobb Chamber or any of the Cobb County business associations. Although it is usually a stand alone event, the 5th Annual Summer J.A.M. was held in conjunction with the Cobb Chamber Expo due to renovations at the Cobb Civic Center. The 2016 Summer J.A.M. will again be combined with the Cobb Chamber Expo. The 6th Annual Summer J.A.M. and Cobb Chamber Expo will take place on Thursday May 19, 2016 from 3:00PM - 7:00PM at The Cobb Galleria Centre.
