The Club Secretary maintains all club records, manages club files, handles club correspondence, and takes the minutes at each club and Club Executive Committee meeting. They are also in charge of updating and distributing a roster of the current paid membership and keeping the club officer list current for Toastmasters International.
Though some clubs combine the Club Secretary role with the Club Treasurer, it is best to have a dedicated Club Secretary who can help reduce the workload of the Club Treasurer, occasionally assist the Vice President Education, and order supplies for the club as needed.
