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.
