Board of Directors and Committees
How the Board Works
With the help of Business Association expert Arte Maren, the Board of Directors reorganized in 2015. The goal was to expedite association business and for each member to clearly understand their role. The following guidelines were established. The Board generate ideas for the association and vote to pursue those considered viable. The appropriate committee chair is selected to develop these ideas. Committee Chairs solicit input from their committees and create a plan (CSW). This is brought to the president for approval, upon which it is put into action. The Executive Director may be called on to assist committee chairs with any part of the process.
