No matter where you live, there’s a Sierra Club chapter or group near you. There are chapters in every state. All chapters have groups, which are organized geographically around local issues.

For example, the Arizona Chapter comprises five groups—the Plateau Group (Flagstaff), the Sedona/Verde Valley Group, the Yavapai Group (Prescott), the Palo Verde Group (Phoenix) and the Rincon Group (Tucson).

Most U.S. chapters generally cover a state, though Washington D.C. has a chapter, and California has 13. Three chapters cover more than one state: the Rio Grande Chapter includes all of New Mexico and a small part of Texas around El Paso, the Northern Rockies Chapter includes all of Idaho and a slice of eastern Washington, and the Toiyabe Chapter includes the eastern Sierra Nevada in California and Nevada.

The Sierra Club has been active in Canada since 1969 and has four chapters there. Sierra Club Canada is a separate legal entity.

Each chapter and group is guided by an executive committee elected by the members. Approximately 5,000 volunteers nationwide are elected or appointed to leadership positions, such as chapter chair, chapter treasurer, committee chair, and outings leader. The Club structure allows us to work on multiple levels to solve problems. Nationwide membership gives the Sierra Club clout with Congress and the White House, while local groups and chapters help us influence city council members, county commissioners, and state officials. The local groups also put pressure on their members of Congress—remember what former House Speaker Tip O’Neill said: “All politics is local.” This one-two punch is a powerful combination.
