Accountability Trees, or Phone Trees; are groups of three alcoholics who commit to visiting with each other by telephone, or meeting face-to-face at least once a week, outside the meeting.  The trees are rotated every three months from the list of voluntary members, and newcomers are always mixed in with experienced sober members.  This expanding out-reach among group members has been remarkable since we established our Accountability Trees.  "One alcoholic talking to another" is the foundation and very cornerstone of the entire AA fellowship, and has worked to strengthen the fellowship of our group and help keep each other accountable in our need to "grow in understanding and effectiveness".
