James (Jimmy) Gisi has a Bachelor’s Degree in Recreation and Leisure Studies from the University of Georgia and a Master’s Degree in Public Administration from Valdosta State University.  He has over 30 years of government management experience in Alma-Bacon County, Camden County and his most recent stint as the Director of Cobb PARKS.  Gisi also served as the Executive Director of the non-profit Georgia Recreation and Park Association for 9 years.

 Gisi has been a frequent instructor for the Carl Vinson Institute of Government at both the Georgia Municipal Association and Association of County Commissioners of Georgia conferences on a range of topics involving recreation management.  He has also taught classes at state, regional and national conferences on various topics.

“Jimmy has worked for the county in various capacities and always stands ready and willing to help anytime we need his assistance,” said County Manager Dr. Jackie 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.”

As Deputy County Manager, Gisi works in support of the County Manager’s office supporting select departments and initiatives.  He has oversight of the county’s SPLOST programs and serves as the county’s official state lobbyist.

A longtime resident of Cobb County, Gisi resides in Powder Springs with his wife, Angela. His two married daughters also live local along with his four grandsons.  Any and all spare time is spent spoiling them any way possible.

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.
