My responsibility to the local chapter has been as  an individual who advises board members and presiding officers on parliamentary procedures to include, (i.e., preparing for meetings, counting  ballots, tracking of those wishing to speak, amendments, motions, handling  procedural questions, maintaining order, etc.). Moreover, during my tenure  I’ve been able to serve as an impartial adviser.
