Membership in the Society is both national and local. The Society's more than 3,100 members are assigned to one of 21 local chapters throughout the United States and Canada. The chapters provide members with an opportunity to get together in smaller groups on a regular basis to discuss matters of common interest. The Society's chapters have their own officers, local meetings, programs and conferences. Chapter meetings, which typically feature speakers and discussion at luncheons, dinners or receptions, afford members an important regular means of contact with and participation in the affairs of the Society. They also are an integral part of the overall networking opportunity the Society offers to its members.
