Our Organization

The Arboretum is led by its Board of Directors, whose members are elected at the Annual Meeting held in May of each year for three-year terms.  The Board meets at least three times per year.  It also conducts business through committees formed by the Board from time to time.  There is an Executive Committee that is empowered to act between regular meetings of the Board, a Finance Committee, a Nominating Committee, a Membership Development Committee and a Horticulture Committee. Committee members can include persons who are not members of the Board.
