ANNA serves its members through a national structure of close to 100 local chapters. Chapters serve as the foundation of ANNA, making Association services locally available to members. By joining one of ANNA's expanding networks of chapters, members can promote their professional growth, advance nephrology nursing practice, and positively influence patient outcomes.

Chapters provide ANNA members with readily accessible educational programs as well as an effective means for membership to provide input into national issues. Chapters circulate important news and views of their members to the National Office, provide ANNA with essential information to effectively plan programming and influence the decision making of the Association, and enhance ANNA's reputation by communicating and collaborating with other nephrology organizations through workshops and special programs.

Chapters offer ANNA members the opportunity to assume leadership roles at the local level. ANNA supports chapter leaders in their leadership development by hosting the annual Volunteer Leaders Workshop and many online resources available in the Chapter Officers Only section.
