About the Deputy County Manager

James (Jimmy) Gisi was named as Cobb County's Deputy County Manager in November of 2020.  Gisi has served as the director of Cobb’s PARKS department since December 2016. He previously held the P.A.R.K.S. director position for 10 years before serving as the executive director of the Georgia Recreation and Park Association.

“Jimmy has worked for the county in various capacities and always stands ready and willing to help anytime we need his assistance,” said McMorris. “His experience working in parks and recreation, as well as government services and legislation, is going to be a great asset to help move the county forward for generations to come.”
“It is truly an honor to be selected as Cobb County’s next deputy county manager. I appreciate the confidence and trust the county manager has placed in me and I look forward to joining her management team,” Gisi said. “Cobb County is truly a great place to live, work, play, and raise a family. Our employees are the best at what they do and we should always strive to maintain our high standards while also seeking to raise the bar of service delivery.”
A longtime resident of Cobb County, Gisi resides in Powder Springs with Angela, his wife of 36 years. He is an ardent college football fan, avid hunter and spoils his three (soon to be four) grandsons anyway he can.

Cobb County's Mission:

To make Cobb County the best place to live and work through an efficient, effective and responsive government that delivers quality services.

We were both honored and challenged when an Atlanta Journal-Constitution poll of metro business and government leaders found that Cobb County was "best in delivering government services."

After all, this is a growing county, already Georgia's third-largest. This means the Cobb management team must continually fine-tune methods and raise standards to preserve the high service level our taxpayers expect and deserve.

So, in keeping with this philosophy, we're pleased to present the Cobb County Government Web site. It's our hope it will serve as a convenient and useful resource of information about this showcase community.

For example, Cobb's water department is considered the best in the nation, our roads program is a regional model, our financial strength ranks Cobb among the nation's top one percent of all counties...and the list goes on.

Certainly, these are points of pride. But they're also challenges we're working hard to meet.
