«Open» meetings allow attendance by anyone interested in learning about Al-Anon Family Groups. People who may come to open meetings occasionally include students and professionals who work with alcoholics and their families.

«Closed» meetings are for members and prospective members whose lives have been affected by someone else’s drinking. Groups that register a meeting as «closed» may decide to hold an occasional «open» meeting in order to reach out to professionals and others interested in Al-Anon.
