The Centennial Group of the Georgia Chapter of the Sierra Club was organized in 1992, the one hundredth anniversary of the Sierra Club. Our members from Cobb, Cherokee, and North Fulton counties volunteer to educate, help, and encourage our fellow citizens to protect Georgia?? "!s environment for our children, grandchildren, and beyond.

We meet on the first Thursday of each month at Life University. We host a variety of programs relating to our goals or simply about Georgia's natural beauties. We also hold free outings for members and nonmembers.
