Regional Chapters have come to play an important role in Company activities. Chapters are organized and administered by local members and host meetings several times a year. Regional chapters do not collect chapter dues, but they usually ask for a small administrative fee to cover mailings, etc. Members of the chapters must be members of the national organization. If you are a Company member and would like to organize a chapter in your area, please e-mail Company Headquarters.
