The Executive Board, is SEAGO's Board of Directors, which is responsible for formulation of policy for the Organization, adoption of a budget, establishment of fees and/or assessments, approving, rejecting or deferring action on any SEAGO business, and the employment and dismissal of an Executive Director. The Executive Board is comprised of one elected official from each of the 19 local government entities: Cochise County, Benson, Bisbee, Douglas, Huachuca City, Sierra Vista, Tombstone, Willcox, Graham County, Pima, Safford,Thatcher, Greenlee County, Clifton, Duncan, Santa Cruz County, Nogales, Patagonia, and the San Carlos Apache Tribe. The Board also contains five private sector representatives. There is one private sector representative from Graham, Greenlee and Santa Cruz Counties, but because the population of Cochise County exceeds 100,000 it is allowed two private sector representatives on the Executive Board. 

The Administrative Council is comprised of one appointed official from each of the 19 local government entities listed above. Each entity's representative on the Administrative Council is the city, town or county manager, city or town clerk, or their delegate. The Administrative Council meets two weeks before each regular meeting of the Executive Board and makes recommendations on all business to be considered by the Board.

The Administrative Committee (comprised of the officers of the Administrative Council) and the Executive Committee (comprised of the officers of the Executive Board), are empowered under the current SEAGO Bylaws to conduct program related, time sensitive business that must be accomplished in between regular meetings of the full Administrative Council and Executive Board. The Administrative Council and Executive Board meet only four times per year. Calling special meetings of the entire Administrative Council (with 19 members) and Executive Board (with 24 members) to conduct business in between regular meetings is extremely difficult, even when several months' notice is provided. As a result, the Bylaws were amended to form the Committees in order to reduce quorum requirements so that business that could not wait until the next regular meeting could be conducted. The Administrative and Executive Committees typically hold four meetings over each calendar year.

The Advisory Council on Aging (ACOA) serves as a forum to allow the elderly of Planning District VI to identify the principal problems confronting them and to determine practical solutions to such problems. Every Area Agency on Aging is required by the Older Americans Act, as amended, to have an advisory council. The members of the ACOA are appointed by the SEAGO Executive Board.
